Visionblue



trypan blue

Dosage Form: injection, solution

Description


Visionblue™ (trypan blue ophthalmic solution) 0.06% is a sterile solution of trypan blue (an acid di-azo group dye). Visionblue™ is a selective tissue staining agent for use as a medical aid in ophthalmic surgery.


Each mL of Visionblue™ 0.06% contains: 0.6 mg trypan blue; 1.9 mg sodium mono-hydrogen orthophosphate (Na2HPO4.2H2O); 0.3 mg sodium di-hydrogen orthophosphate (NaH2PO4.2H2O); 8.2 mg sodium chloride (NaCl); and water for injection. The pH is 7.3 - 7.6. The osmolality is 257-314 mOsm/kg.


The drug substance trypan blue has the chemical name 3,3’-[(3,3’-dimethyl-4,4’-biphenylylene) bis (azo)] bis(5-amino-4-hydroxy-2,7-naphthalenedisulfonic acid) tetra sodium salt, a molecular weight of 960.8, a molecular formula of C34H24N6Na4O14S4, and has the following chemical structure:




Clinical Pharmacology


Visionblue™ selectively stains connective tissue structures in the human eye such as the anterior lens capsule of the human crystalline lens.


Visionblue™ is intended to be applied directly on the anterior lens capsule, staining any portion of the capsule which comes in contact with the dye. Excess dye is washed out of the anterior chamber. The dye does not penetrate the capsule, permitting visualization of the anterior capsule in contrast to the non‑stained lens cortex and inner lens material.



Indications and Usage


Visionblue™ is indicated for use as an aid in ophthalmic surgery by staining the anterior capsule of the lens.


Contraindications


Visionblue™ is contraindicated when a non-hydrated (dry state), hydrophilic acrylic intraocular lens (IOL) is planned to be inserted into the eye because the dye may be absorbed by the IOL and stain the IOL.



Precautions




General


It is recommended that after injection all excess Visionblue™ be immediately removed from the eye by thorough irrigation of the anterior chamber.



Carcinogenesis, mutagenesis, impairment of fertility


Trypan blue is carcinogenic in rats. Wister/Lewis rats developed lymphomas after receiving subcutaneous injections of 1% trypan blue dosed at 50 mg/kg every other week for 52 weeks (total dose approximately 1,250,000-fold the maximum recommended human dose of 0.06 mg per injection in a 60 kg person, assuming total absorption).


Trypan blue was mutagenic in the Ames test and caused DNA strand breaks in vitro.



Pregnancy


Teratogenic Effects: Pregnancy Category C.

Trypan blue is teratogenic in rats, mice, rabbits, hamsters, dogs, guinea pigs, pigs, and chickens. The majority of teratogenicity studies performed involve intravenous, intraperitoneal, or subcutaneous administration in the rat. The teratogenic dose is 50 mg/kg as a single dose or 25 mg/kg/day during embryogenesis in the rat. These doses are approximately 50,000- and 25,000-fold the maximum recommended human dose of 0.06 mg per injection based in a 60 kg person, assuming that the whole dose is completely absorbed. Characteristic anomalies included neural tube, cardiovascular, vertebral, tail, and eye defects. Trypan blue also caused an increase in post-implantation mortality, and decreased fetal weight. In the monkey, trypan blue caused abortions with single or two daily doses of 50 mg/kg between 20th to 25th days of pregnancy, but no apparent increase in birth defects (approximately 50,000-fold maximum recommended human dose of 0.06 mg per injection, assuming total absorption). There are no adequate and well-controlled studies in pregnant women. Trypan blue should be given to a pregnant woman only if the potential benefit justifies the potential risk to the fetus.



Nursing mothers


It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when trypan blue is administered to a nursing woman.



Pediatric use


The safety and effectiveness of trypan blue have been established in pediatric patients. Use of trypan blue is supported by evidence from an adequate and well-controlled study in pediatric patients.



Geriatric use


No overall differences in safety and effectiveness have been observed between elderly and younger patients.



Adverse Reactions


Adverse reactions reported following use of Visionblue™ include discoloration of high water content hydrogen intraocular lenses (see Contraindications) and inadvertent staining of the posterior lens capsule and vitreous face.  Staining of the posterior lens capsule or staining of the vitreous face is generally self limited, lasting up to one week.



Dosage and Administration


Cataract surgery

Visionblue™ is packaged in a 2.25 mL syringe to which a blunt cannula has to be attached.


After opening the eye, an air bubble is injected into the anterior chamber of the eye in order to minimize dilution of Visionblue™ by the aqueous. Visionblue™ is carefully applied onto the anterior lens capsule using a blunt cannula. Sufficient staining is achieved as soon as the dye has contacted the capsule. The anterior chamber is then irrigated with balanced salt solution to remove all excess dye. An anterior capsulotomy can then be performed.



How Supplied


Visionblue™ 0.06% is supplied as follows:


0.5 mL of Visionblue™ in a sterile single-use Luer Lok, 2.25 mL glass syringe, grey rubber plunger stopper and tip cap with polypropylene plunger rod in a peel pouch. 



Storage and Handling


Visionblue™ is stored at 15-25ºC (59-77ºF). Protect from direct sunlight.

Q. What Is In Adcortyl Intra-Articular / Intradermal (Ia/Id) Injection?



A. Adcortyl IA/ID Injection belongs to a group of medicines called steroids. Their full name is corticosteroids. These corticosteroids occur naturally in the body, and help to maintain health and well-being. Boosting your body with extra corticosteroid (such as Adcortyl IA/ID Injection) is an effective way to treat various illnesses involving inflammation in the body. Adcortyl IA/ID Injection reduces this inflammation, which could otherwise go on making your condition worse. You must take this medicine regularly to get maximum benefit from it.



The injection contains triamcinolone acetonide 10mg/ml and is supplied in packs of 5 x 1.0ml glass ampoules or a single 5ml glass vial. The other ingredients are benzyl alcohol, polysorbate 80, carmellose, sodium chloride and water for injection.

Q. What Is This Medicine For?



A. Adcortyl IA/ID Injection is for the treatment of joint pain, swelling and stiffness in inflammatory disorders such as rheumatoid arthritis. It is also used to treat various forms of allergic dermatitis, skin overgrowths such as
thickened scar tissue, and patchy baldness, which is usually reversible.





Before Receiving Your Medicine




Q. Should I be receiving Adcortyl IA/ID injection?



A. You should not receive this medicine if you have ever had an allergic reaction to similar medicines or to any of the ingredients in Adcortyl IA/ID injection. You should not receive this medicine if you are suffering from an infection
unless your doctor has also prescribed a treatment for the infection.





Q. Is there anything else I should discuss with my doctor before receiving Adcortyl IA/ID injection?



A. Check with your doctor before receiving Adcortyl IA/ID injection if you have had any recent infection, tuberculosis (TB), bowel disorders, an ulcer, blood clots, cancer, thin (brittle) bones, high blood pressure or heart failure, mental disorders, epilepsy, myasthenia gravis or glaucoma (increased pressure in your eyes).



Check with your doctor first:



  • If you have ever had severe depression or manic-depression (bipolar disorder). This includes having had depression before while taking steroid medicines like Adcortyl IA/ID Injection.


  • If any of your close family has had these illnesses.

If either of these applies to you, talk to a doctor before taking Adcortyl IA/ID Injection.





Q. What if I have been in contact with someone who has an infectious disease such as Chickenpox, Shingles or Measles?



A. Steroid medicines suppress your body's natural immune response. Therefore, if you come into contact with anyone who has an infectious disease such as chickenpox, shingles or measles, consult your doctor promptly, especially if you have not had the disease before. You should take particular care to avoid these diseases.





Q. Can I be immunised (vaccinated)?



A. While you are being treated with this medicine (or if you have recently stopped a course of treatment) do not have any immunisation without consulting your doctor.





Q. What if I am pregnant or think I may be pregnant? What if I am planning to become pregnant? What if I am breast-feeding?



A. You should make sure you discuss this with your doctor as soon as possible before receiving Adcortyl IA/ID injection.





Q. What if I have had problems with my kidneys, liver or thyroid?



A. Remind your doctor as the dose of Adcortyl may need to be adjusted.





Q. Can I take other medicines?



A. Corticosteroids can increase the chance of bleeding from the gut caused by aspirin, ibuprofen or other non-steroidal anti-inflammatory drugs (NSAIDs). If you have hypothrombinaemia (a tendency to bleed), your doctor will be
more careful about giving you Adcortyl IA/ID injection if you are taking ibuprofen or another NSAID. Always tell your doctor about all other medicines you are taking, even those you have bought at a pharmacy or other places, e.g. supermarket. Some medicines used to treat epilepsy, tuberculosis or breast cancer can reduce the effectiveness of Adcortyl. On the other hand, Adcortyl can affect the action of some medicines used to treat diabetes, high blood pressure or to thin the blood.



Always tell your doctor if you are taking oral contraceptives, hormone replacement therapy (HRT), growth hormone, thyroid drugs, cyclosporin, or medicines for treating fungal infections, or if you are to be vaccinated or to be given an anaesthetic.





Q. Is it all right to take exercise?



A. You must take care not to over-use a joint which feels better after you receive Adcortyl IA/ID injection as the joint will still need to recover from the inflammation which caused your symptoms.





Q. Is it all right to drive?



A. This medicine does not usually affect your ability to drive but it can affect your eyesight. Tell your doctor immediately if you have any pain in the eyes or visual disturbances.





Q. Is it all right to drink alcohol?



A. There is no known interaction between Adcortyl and alcohol.





Q. What if I am diabetic?



A. Remind your doctor as your insulin dose may need to be changed.





Q. Who should I tell that I have received this injection?



A. Your doctor or pharmacist will have given you a Steroid Treatment Card with your prescription or medicine. YOU SHOULD ALWAYS CARRY THIS CARD WITH YOU as it must be shown to any of the following persons:



  • Doctor or Nurse - before having any surgery or emergency treatment or if any new treatment is prescribed.


  • Dentist - before having any dental surgery


  • Pharmacist - before buying any medicine


  • Optician - it is advisable to have regular eye tests




Q. Is there any important information about the ingredients of Adcortyl that I need to know?



A. Adcortyl IA/ID Injection contains 15mg/ml benzyl alcohol which may cause harmful or allergic reactions in infants and children. Adcortyl IA/ID injection must not be given to premature or newly born babies.






Administraton Of Your Medicine




Q. How will Adcortyl IA/ID injection be given and how often?



A. The effect of the injection will vary from patient to patient and further injections may be given when symptoms return and not at regular intervals.



Use in inflammatory joint disorders:



The dose of injection to be given into a joint or into a tendon sheath depends upon the size of the joint to be treated and the severity of the condition. Doses of 2.5 - 5mg (0.25-0.5ml) for smaller joints and 5-15mg (0.5-1.5ml) for larger joints usually give relief of symptoms. This medicine should not be used for injection into the Achilles tendon.



Use in allergic dermatitis:



The dose is usually 2-3mg (0.2-0.3ml) depending on the size of the problem area of the skin but no more than 5mg (0.5ml) should be injected at any one site. If several sites are injected the total dose given should not exceed 30mg (3ml). Further doses may be given if necessary at one or two week intervals.



Children: Adcortyl IA/ID is not recommended for children under 6 years of age. It may be given to older children but the dose is adjusted according to their size and weight and is always kept as low as possible for the shortest possible time.



During times of illness or stress, patients on long-term treatment may require the addition of oral steroid tablets or, if they have recently finished a course of Adcortyl IA/ID injections, may need to start taking oral steroid tablets for
a while.





Q. How long should I continue receiving Adcortyl IA/ID injection?



A. Your doctor will advise you whether it is wise for you to have further injections.



Treatment with steroids is usually kept as short as possible and must not be stopped abruptly. Joints may become permanently damaged by repeated injections over a long period of time.



When the treatment is stopped you may notice flu-like symptoms, runny nose or itchy eyes or skin.



Mental problems while taking Adcortyl IA/ID injection



Mental health problems can happen while taking steroids like Adcortyl IA/ID Injection (see also section 4 Possible Side Effects).



  • These illnesses can be serious.


  • Usually they start within a few days or weeks of starting the medicine.


  • They are more likely to happen at high doses.


  • Most of these problems go away if the dose is lowered or the medicine is stopped. However, if problems do happen they might need treatment.

Talk to a doctor if you (or someone taking this medicine), shows any signs of mental problems. This is particularly important if you are depressed, or might be thinking about suicide. In a few cases, mental problems have happened when doses are being lowered or stopped.






Undesirable Effects




Q. Are there any unwanted effects of Adcortyl IA/ID injection?



A. All medicines may cause some unwanted or “side” effects. Some which can occur with steroid treatment are as follows. Tell your doctor immediately if you get ulcer pains in your stomach or severe pain in your abdomen, facial swelling or an unexpected rash. Patients have reported increased appetite, weight gain, indigestion, sickness, feeling tired or weak. Steroid treatment may cause increased risk of infection, thinning of bones or tendons causing fractures or torn muscles, water retention, irregular heart beat, high blood pressure or blood clots. Skin disorders or eye problems, including glaucoma and cataracts, may occur and wounds or broken bones may be slow to heal. Treatment with steroids can stop the body from producing some hormones and may slow or stop children’s growth rate. If you are female, your periods may become irregular. Elevation or depression of mood, sleeplessness and severe headaches have been reported. Very rare instances of blindness have been reported following injection to the face.



In particular, when Adcortyl IA/ID is injected into a joint you may notice some indentation appearing after a while in the surrounding area. There may also be some temporary worsening of the pain and discomfort after the injection. Similarly, injections given under the skin may cause slight changes in skin colour around the site of injection. These changes should disappear in time.



Serious effects: tell a doctor straight away



Steroids including Adcortyl IA/ID injection can cause serious mental health problems. These are common in both adults and children. They can affect about 5 in every 100 people taking medicines like Adcortyl IA/ID injection.



  • Feeling depressed, including thinking about suicide.


  • Feeling high (mania) or moods that go up and down.


  • Feeling anxious, having problems sleeping, difficulty in thinking or being confused and losing your memory.


  • Feeling, seeing or hearing things which do not exist. Having strange and frightening thoughts, changing how you act or having feelings of being alone.

If you notice any of these problems talk to a doctor straight away.



Tell your doctor or pharmacist if you notice any other troublesome side effects.






Looking After Your Medicine



Adcortyl IA/ID injection will be kept in the pharmacy until it is given to you by your doctor or nurse. It should be stored upright, at a temperature not exceeding 25°C and should not be allowed to freeze. After first opening, the
5ml multidose vial may be stored for 28 days below 25°C. It should not be used after the expiry date shown on the outer packaging. Keep out of reach and sight of children.

Active or history of recurrent peptic ulcer/haemorrhage (two or more distinct episodes of proven ulceration or bleeding).



History of gastrointestinal bleeding or perforation, related to previous NSAIDs therapy.



Severe heart failure, renal failure or hepatic failure (see section 4.4)



Last trimester of pregnancy (see section 4.6).



4.4 Special Warnings And Precautions For Use



Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms (see GI and cardiovascular risks below).



The elderly have an increased frequency of adverse reactions to NSAIDs especially gastrointestinal bleeding and perforation which may be fatal.



Respiratory:



Bronchospasm may be precipitated in patients suffering from, or with a previous history of bronchial asthma or allergic disease.



Other NSAIDs:



The use of Ibuprofen with concomitant NSAIDs including cyclooxygenase-2 selective inhibitors should be avoided (see section 4.5).



SLE and mixed connective tissue disease:



Systemic lupus erythematosus and mixed connective tissue disease – increased risk of aseptic meningitis (See section 4.8).



Renal:



Renal impairment as renal function may further deteriorate (see sections 4.3 and 4.8).



Hepatic:



Hepatic dysfunction (see sections 4.3 and 4.8)



Cardiovascular and cerebrovascular effects:



Caution (discussion with doctor or pharmacist) is required prior to starting treatment in patients with a history of hypertension and/or heart failure as fluid retention, hypertension and oedema have been reported in association with NSAID therapy.



Clinical trial and epidemiological data suggest that use of ibuprofen, particularly at high doses (2400mg daily) and in long-term treatment may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke). Overall, epidemiological studies do not suggest that low dose ibuprofen (e.g.



Impaired female fertility:



There is limited evidence that drugs which inhibit cyclo-oxygenase/prostaglandin synthesis may cause impairment of female fertility by an effect on ovulation. This is reversible upon withdrawal of treatment.



Gastrointestinal:



NSAIDs should be given with care to patients with a history of gastrointestinal disease (ulcerative colitis, Crohn's disease) as these conditions may be exacerbated (see section 4.8).



GI bleeding, ulceration or perforation, which can be fatal has been reported with all NSAIDs at anytime during treatment, with or without warning symptoms or a previous history of GI events.



The risk of GI bleeding, ulceration or perforation is higher with increasing NSAID doses, in patients with a history of ulcer, particularly if complicated with haemorrhage or perforation (see section 4.3), and in the elderly. These patients should commence treatment on the lowest dose available.



Patients with a history of GI toxicity, particularly the elderly, should report any unusual abdominal symptoms (especially GI bleeding) particularly in the initial stages of treatment.



Caution should be advised in patients receiving concomitant medications which could increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective serotonin-reuptake inhibitors or anti-platelet agents such as aspirin (see section 4.5).



When GI bleeding or ulceration occurs in patients receiving ibuprofen, the treatment should be withdrawn.



Dermatological:



Serious skin reactions, some of them fatal, including exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis, have been reported very rarely in association with the use of NSAIDs (see section 4.8). Patients appear to be at highest risk for these reactions early in the course of therapy: the onset of the reaction occurring in the majority of cases within the first month of treatment. Ibuprofen should be discontinued at the first appearance of skin rash, mucosal lesions, or any other sign of hypersensitivity.

• Are pregnant



If symptoms persist or worsen, consult your doctor or pharmacist.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



The following drug interactions have been identified for ibuprofen acid:



Ibuprofen (like other NSAIDs) should be avoided in combination with:



Aspirin: unless low-dose aspirin (not above 75mg daily) has been advised by a doctor as this may increase the risk of adverse reactions (see Section 4.4).



Experimental data suggest that ibuprofen may inhibit the effect of low dose aspirin on platelet aggregation when they are dosed concomitantly. However, the limitations of these data and the uncertainties regarding extrapolation of ex vivo data to the clinical situation imply that no firm conclusions can be made for regular ibuprofen use, and no clinically relevant effect is considered to be likely for occasional ibuprofen use (see section 5.1).



Other NSAIDs including cyclooxygenase-2 selective inhibitors: Avoid concomitant use of two or more NSAIDs as this may increase the risk of adverse effects (see section 4.4)



Ibuprofen should be used with caution in combination with:



Corticosteroids: as these may increase the risk of gastrointestinal ulceration or bleeding (see Section 4.4)



Antihypertensives and diuretics: since NSAIDs may diminish the effects of these drugs. Diuretics can increase the risk of nephrotoxicity of NSAIDs.



Anticoagulants. NSAIDs may enhance the effects of anti-coagulants, such as warfarin (See section 4.4).



Anti-platelet agents and selective serotonin reuptake inhibitors (SSRIs): increased risk of gastrointestinal bleeding (see section 4.4).



Cardiac glycosides: NSAIDs may exacerbate cardiac failure, reduce GFR and increase plasma glycoside levels.



Lithium: There is evidence for potential increase in plasma levels of lithium.



Methotrexate: There is evidence for the potential increase in plasma levels of methotrexate.



Ciclosporin: Increased risk of nephrotoxicity.



Mifepristone: NSAIDs should not be used for 8-12 days after mifepristone administration as NSAIDs can reduce the effect of mifepristone.



Tacrolimus: Possible increased risk of nephrotoxicity when NSAIDs are given with tacrolimus.



Zidovudine: Increased risk of haematological toxicity when NSAIDs are given with zidovudine. There is evidence of an increased risk haemarthroses and haematoma in HIV (+) haemophiliacs receiving concurrent treatment with zidovudine and ibuprofen.



Quinolone antibiotics:Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone antibiotics. Patients taking NSAIDs and quinolones may have an increased risk of developing convulsions.



4.6 Pregnancy And Lactation



No specific studies have been conducted with ibuprofen lysine.



Whilst no teratogenic effects have been demonstrated in animal experiments, the use of Nurofen Migraine Pain should, if possible, be avoided during the first 6 months of pregnancy.



During the 3rd trimester, ibuprofen is contraindicated as there is a risk of premature closure of the foetal ductus arteriosus with possible persistent pulmonary hypertension. The onset of labour may be delayed and the duration increased with an increased bleeding tendency in both mother and child. (See section 4.3 Contraindications).



In limited studies, ibuprofen appears in the breast milk in very low concentration and is unlikely to affect the breast-fed infant adversely.



See section 4.4 regarding female fertility.



4.7 Effects On Ability To Drive And Use Machines



None expected at recommended doses and duration of therapy.



4.8 Undesirable Effects



Possible side effects are those experienced with ibuprofen acid. These may include:



Hypersensitivity reactions have been reported following treatment with ibuprofen. These may consist of (a) non-specific allergic reaction and anaphylaxis, (b) respiratory tract activity comprising asthma, aggravated asthma, bronchospasm or dyspnoea, or (c) assorted skin disorders, including rashes of various types, pruritis, urticaria, purpura, angioedema and, more rarely, bullous dermatoses (including epidermal necrolysis and erythema multiforme).



The list of the following adverse effects relates to those experienced with NSAIDS at doses available over the counter for short-term use. In the treatment of chronic conditions, under long-term treatment, additional adverse effects may occur.



Hypersensitivity reactions:



Uncommon: Hypersensitivity reactions with urticaria and pruritis



Very rare: severe hypersensitivity reactions. Symptoms could be facial, tongue and laryngeal swelling, dysponoea, tachycardia, hypotension, (anaphylaxis, angioedema or severe shock).



Exacerbation of asthma and bronchospasm.



Gastrointestinal:



The most commonly observed adverse events are gastrointestinal in nature.



Uncommon: abdominal pain, nausea, dyspepsia



Rare: Diarrhoea, flatulence, constipation and vomiting



Very rare: peptic ulcer, perforation or gastrointestinal haemorrhage, melaena, haematemesis, sometimes fatal, particularly in the elderly. Ulcerative stomatitis, gastritis.



Exacerbation of colitis and Crohn's disease (section 4.4).



Nervous System:



Uncommon: Headache



Very rare: Aseptic meningitis – single cases have been reported very rarely.



Renal:



Very rare: Acute renal failure, papillary necrosis, especially in long-term use, associated with increased serum and oedema.



Hepatic:



Very rare: liver disorders.



Haematological:



Very rare: Haematopoietic disorders (anaemia, leucopenia, thrombocytopenia, pancytopenia, agranulocytosis). First signs are fever, sore throat, superficial mouth ulcers, flu-like symptoms, severe exhaustion, unexplained bleeding and bruising.



Dermatological:



Uncommon: Various skin rashes



Very rare: Severe forms of skin reactions such as bullous reactions including Stevens-Johnson syndrome, erythema multiforme and toxic epidermal necrolysis can occur.



Immune System:



In patients with existing auto-immune disorders (such as systemic lupus erythematosus, mixed connective tissue disease) during treatment with ibuprofen, single cases of symptoms of aseptic meningitis, such as stiff neck, headache, nausea, vomiting, fever or disorientation have been observed (see section 4.4).



Cardiovascular and Cerebrovascular



Oedema, hypertension and cardiac failure, have been reported in association with NSAID treatment.



Clinical trial and epidemiological data suggest that the use of NSAIDS (particularly at high doses 2400 mg daily) and in long-term treatment may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke) (see section 4.4).



4.9 Overdose



In children ingestion of more than 400 mg/kg may cause symptoms. In adults the dose response effect is less clear cut. The half-life in overdose is 1.5-3 hours.



Symptoms



Most patients who have ingested clinically important amounts of NSAIDs will develop no more than nausea, vomiting, epigastric pain, or more rarely diarrhoea. Tinnitus, headache and gastrointestinal bleeding are also possible. In more serious poisoning, toxicity is seen in the central nervous system, manifesting as drowsiness, occasionally excitation and disorientation or coma. Occasionally patients develop convulsions. In serious poisoning metabolic acidosis may occur and the prothrombin time/ INR may be prolonged, probably due to interference with the actions of circulating clotting factors. Acute renal failure and liver damage may occur. Exacerbation of asthma is possible in asthmatics.



Management



Management should be symptomatic and supportive and include the maintenance of a clear airway and monitoring of cardiac and vital signs until stable. Consider oral administration of activated charcoal if the patient presents within 1 hour of ingestion of a potentially toxic amount. If frequent or prolonged, convulsions should be treated with intravenous diazepam or lorazepam. Give bronchodilators for asthma.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Ibuprofen lysine is the lysine salt of ibuprofen, a propionic acid derivative, having analgesic, anti-inflammatory and antipyretic activity. The therapeutic effects of ibuprofen lysine as a non steroidal anti-inflammatory drug are thought to result from inhibitory activity on prostaglandin synthesis.



Following oral administration, ibuprofen lysine dissociates to ibuprofen acid and lysine. Lysine has no recognised pharmacological activity. The pharmacological properties of ibuprofen lysine, therefore, are the same as those of ibuprofen acid.



Experimental data suggest that ibuprofen may inhibit the effect of low dose aspirin on platelet aggregation when they are dosed concomitantly. In one study, when a single dose of ibuprofen 400mg was taken within 8 h before or within 30 min after immediate release aspirin dosing (81mg), a decreased effect of ASA on the formation of thromboxane or platelet aggregation occurred. However, the limitations of these data and the uncertainties regarding extrapolation of ex vivo data to the clinical situation imply that no firm conclusions can be made for regular ibuprofen use, and no relevant effect is considered to be likely for occasional ibuprofen use.



5.2 Pharmacokinetic Properties



Most pharmacokinetic data obtained following the administration of ibuprofen acid also apply to ibuprofen lysine.



Peak plasma concentrations occur 1-2 hours after administrations of ibuprofen acid. However, ibuprofen is more rapidly absorbed from the gastrointestinal tract following the administration of Nurofen Migraine Pain tablets/Nurofen Tension headache, with peak plasma concentrations occurring approximately 35 minutes after administration in the fasting state.



The elimination half-life of ibuprofen acid is approximately 2 hours.



The drug is extensively bound to plasma proteins.



Ibuprofen is metabolised in the liver to two inactive metabolites and these, together with unchanged ibuprofen, are excreted by the kidney either as such or as conjugates. Excretion by the kidney is both rapid and complete.



No specific difference in pharmacokinetic profile is observed in the elderly.



5.3 Preclinical Safety Data



No relevant information additional to that contained elsewhere within the SmPC.

Novarel



chorionic gonadotropin

Dosage Form: for Injection, USP

Novarel Description


Human chorionic gonadotropin (HCG), a polypeptide hormone produced by the human placenta, is composed of an alpha and a beta sub-unit. The alpha sub-unit is essentially identical to the alpha sub-units of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha sub-unit of human thyroid-stimulating hormone (TSH). The beta sub-units of these hormones differ in amino acid sequence.


Chorionic Gonadotropin is a water soluble glycoprotein derived from human pregnancy urine. The sterile lyophilized powder is stable. When reconstituted with Bacteriostatic Water for Injection preserved with benzyl alcohol 0.9%, the solution should be refrigerated and used within 30 days.


Each vial contains:


Chorionic Gonadotropin 10,000 USP Units, Mannitol 100 mg, Dibasic Sodium Phosphate 16 mg, and Monobasic Sodium Phosphate 4 mg.



Novarel - Clinical Pharmacology


The action of HCG is virtually identical to that of pituitary LH, although HCG appears to have a small degree of FSH activity as well. It stimulates production of gonadal steroid hormones by stimulating the interstitial cells (Leydig cells) of the testis to produce androgens and the corpus luteum of the ovary to produce progesterone. Androgen stimulation in the male leads to the development of secondary sex characteristics and may stimulate testicular descent when no anatomical impediment to descent is present. This descent is usually reversible when HCG is discontinued. During the normal menstrual cycle, LH participates with FSH in the development and maturation of the normal ovarian follicle, and the mid-cycle LH surge triggers ovulation. HCG can substitute for LH in this function.


During a normal pregnancy, HCG secreted by the placenta maintains the corpus luteum after LH secretion decreases, supporting continued secretion of estrogen and progesterone, and preventing menstruation. HCG HAS NO KNOWN EFFECT ON FAT MOBILIZATION, APPETITE OR SENSE OF HUNGER, OR BODY FAT DISTRIBUTION.



Indications and Usage for Novarel


HCG HAS NOT BEEN DEMONSTRATED TO BE EFFECTIVE ADJUNCTIVE THERAPY IN THE TREATMENT OF OBESITY. THERE IS NO SUBSTANTIAL EVIDENCE THAT IT INCREASES WEIGHT LOSS BEYOND THAT RESULTING FROM CALORIC RESTRICTION, THAT IT CAUSES A MORE ATTRACTIVE OR “NORMAL” DISTRIBUTION OF FAT, OR THAT IT DECREASES THE HUNGER AND DISCOMFORT ASSOCIATED WITH CALORIE-RESTRICTED DIETS.



  1. Prepubertal cryptorchidism not due to anatomic obstruction. In general, HCG is thought to induce testicular descent in situations when descent would have occurred at puberty. HCG thus may help to predict whether or not orchiopexy will be needed in the future. Although, in some cases, descent following HCG administration is permanent, in most cases the response is temporary. Therapy is usually instituted between the ages of 4 and 9.




  2. Selected cases of hypogonadotropic hypogonadism (hypogonadism secondary to a pituitary deficiency) in males.




  3. Induction of ovulation and pregnancy in the anovulatory, infertile woman in whom the cause of anovulation is secondary and not due to primary ovarian failure, and who has been appropriately pretreated with human menotropins.




Contraindications


Precocious puberty, prostatic carcinoma or other androgen-dependent neoplasm, prior allergic reaction to HCG. HCG may cause fetal harm when administered to a pregnant woman. Combined HCG/PMS (pregnant mare’s serum) therapy has been noted to induce high incidences of external congenital anomalies in the offspring of mice, in a dose-dependent manner. The potential extrapolation to humans has not been determined.



Warnings


HCG should be used in conjunction with human menopausal gonadotropins only by physicians experienced with infertility problems who are familiar with the criteria for patient selection, contraindications, warnings, precautions, and adverse reactions described in the package insert for menotropins. The principal serious adverse reactions during this use are: (1) Ovarian hyperstimulation, a syndrome of sudden ovarian enlargement, ascites with or without pain, and/or pleural effusion; (2) Enlargement of preexisting ovarian cysts or rupture of ovarian cysts with resultant hemoperitoneum; (3) Multiple births, and (4) Arterial thromboembolism.


The recommended diluent for reconstitution is Bacteriostatic Water for Injection preserved with benzyl alcohol 0.9%. Benzyl alcohol has been reported to be associated with a fatal “Gasping Syndrome” in premature infants.



Precautions



General



  1. Induction of androgen secretion by HCG may induce precocious puberty in patients treated for cryptorchidism. Therapy should be discontinued if signs of precocious puberty occur.




  2. Since androgens may cause fluid retention, HCG should be used with caution in patients with cardiac or renal disease, epilepsy, migraine, or asthma.




Drug/Laboratory test


HCG can crossreact in the radioimmunoassay of gonadotropins, especially luteinizing hormone. Each individual laboratory should establish the degree of crossreactivity with their gonadotropin assay. Physicians should make the laboratory aware of patients on HCG if gonadotropin levels are requested.



Carcinogenesis, Mutagenesis, Impairment of Fertility


There have been sporadic reports of testicular tumors in otherwise healthy young men receiving HCG for secondary infertility. A causative relationship between HCG and tumor development in these men has not been established. Defects of forelimbs and of the central nervous system, as well as alterations in sex ratio, have been reported in mice on combined gonadotropin and HCG regimens. The dose of gonadotropin used was intended to induce superovulation. No mutagenic effect has been clearly established in humans. Fertility—see “Indications and Usage.”



Pregnancy


Teratogenic Effects

Category X: See “Contraindications” section. Combined HCG/PMS (pregnant mare’s serum) therapy has been noted to induce high incidences of external congenital anomalies in the offspring of mice, in a dose-dependent manner. The potential extrapolation to humans has not been determined.



Nursing Mothers


It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when HCG is administered to a nursing woman.



Pediatric Use


Safety and effectiveness in children below the age of 4 have not been established.



Adverse Reactions


(See WARNINGS) Headache, irritability, restlessness, depression, fatigue, edema, precocious puberty, gynecomastia, pain at the site of injection. Hypersensitivity reactions both localized and systemic in nature, including erythema, urticaria, rash, angioedema, dyspnea and shortness of breath, have been reported. The relationship of these allergic-like events to the polypeptide hormone or the diluent containing benzyl alcohol is not clear.



Novarel Dosage and Administration


(Intramuscular Use Only): The dosage regimen employed in any particular case will depend upon the indication for use, the age and weight of the patient, and the physician’s preference. The following regimens have been advocated by various authorities.


Prepubertal cryptorchidism not due to anatomical obstruction:


(1) 4,000 USP Units three times weekly for three weeks.


(2) 5,000 USP Units every second day for four injections.


(3) 15 injections of 500 to 1,000 USP Units over a period of six weeks.


(4) 500 USP Units three times weekly for four to six weeks. If this course of treatment is not successful, another is begun one month later, giving 1,000 USP Units per injection.


Selected cases of hypogonadotropic hypogonadism in males:


(1) 500 to 1,000 USP Units three times a week for three weeks, followed by the same dose twice a week for three weeks.


(2) 4,000 USP Units three times weekly for six to nine months, following which the dosage may be reduced to 2,000 USP Units three times weekly for an additional three months.


Induction of ovulation and pregnancy in the anovulatory, infertile woman in whom the cause of anovulation is secondary and not due to primary ovarian failure and who has been appropriately pre-treated with human menotropins (See prescribing information for menotropins for dosage and administration for that drug product).


5,000 to 10,000 USP Units one day following the last dose of menotropins. (A dosage of 10,000 USP Units is recommended in the labeling for menotropins).


Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Fluconazole




Fluconazole

Fluconazole Tablets

Fluconazole Injection - for intravenous infusion only

Fluconazole for Oral Suspension

Fluconazole Description


Fluconazole, the first of a new subclass of synthetic triazole antifungal agents, is available as tablets for oral administration, as a powder for oral suspension, and as a sterile solution for intravenous use in Viaflex® Plus plastic containers.


Fluconazole is designated chemically as 2,4-difluoro-α,α1-bis(1H-1,2,4-triazol-1-ylmethyl) benzyl alcohol with an empirical formula of C13H12F2N6O and molecular weight of 306.3. The structural formula is:



Fluconazole is a white crystalline solid which is slightly soluble in water and saline.


Fluconazole Tablets contain 50, 100, 150, or 200 mg of Fluconazole and the following inactive ingredients: microcrystalline cellulose, dibasic calcium phosphate anhydrous, povidone, croscarmellose sodium, FD&C Red No. 40 aluminum lake dye, and magnesium stearate.


Fluconazole for Oral Suspension contains 350 mg or 1400 mg of Fluconazole and the following inactive ingredients: sucrose, sodium citrate dihydrate, citric acid anhydrous, sodium benzoate, titanium dioxide, colloidal silicon dioxide, xanthan gum, and natural orange flavor. After reconstitution with 24 mL of distilled water or Purified Water (USP), each mL of reconstituted suspension contains 10 mg or 40 mg of Fluconazole.


Fluconazole Injection is an iso-osmotic, sterile, nonpyrogenic solution of Fluconazole in a sodium chloride or dextrose diluent. Each mL contains 2 mg of Fluconazole and 9 mg of sodium chloride or 56 mg of dextrose, hydrous. The pH ranges from 4.0 to 8.0 in the sodium chloride diluent and from 3.5 to 6.5 in the dextrose diluent. Injection volumes of 100 mL and 200 mL are packaged in Viaflex® Plus plastic containers.


The Viaflex® Plus plastic container is fabricated from a specially formulated polyvinyl chloride (PL 146® Plastic) (Viaflex and PL 146 are registered trademarks of Baxter International, Inc.). The amount of water that can permeate from inside the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g., di-2-ethylhexylphthalate (DEHP), up to 5 parts per million. However, the suitability of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by tissue culture toxicity studies.



Fluconazole - Clinical Pharmacology



Pharmacokinetics and Metabolism


The pharmacokinetic properties of Fluconazole are similar following administration by the intravenous or oral routes. In normal volunteers, the bioavailability of orally administered Fluconazole is over 90% compared with intravenous administration. Bioequivalence was established between the 100 mg tablet and both suspension strengths when administered as a single 200 mg dose.


Peak plasma concentrations (Cmax) in fasted normal volunteers occur between 1 and 2 hours with a terminal plasma elimination half-life of approximately 30 hours (range: 20–50 hours) after oral administration.


In fasted normal volunteers, administration of a single oral 400 mg dose of Fluconazole leads to a mean Cmax of 6.72 µg/mL (range: 4.12 to 8.08 µg/mL) and after single oral doses of 50–400 mg, Fluconazole plasma concentrations and AUC (area under the plasma concentration-time curve) are dose proportional.


The Cmax and AUC data from a food-effect study involving administration of Fluconazole tablets to healthy volunteers under fasting conditions and with a high-fat meal indicated that exposure to the drug is not affected by food. Therefore, Fluconazole may be taken without regard to meals. (see DOSAGE AND ADMINISTRATION.)


Administration of a single oral 150 mg tablet of Fluconazole to ten lactating women resulted in a mean Cmax of 2.61 µg/mL (range: 1.57 to 3.65 µg/mL).


Steady-state concentrations are reached within 5–10 days following oral doses of 50–400 mg given once daily. Administration of a loading dose (on day 1) of twice the usual daily dose results in plasma concentrations close to steady-state by the second day. The apparent volume of distribution of Fluconazole approximates that of total body water. Plasma protein binding is low (11–12%). Following either single- or multiple oral doses for up to 14 days, Fluconazole penetrates into all body fluids studied (see table below). In normal volunteers, saliva concentrations of Fluconazole were equal to or slightly greater than plasma concentrations regardless of dose, route, or duration of dosing. In patients with bronchiectasis, sputum concentrations of Fluconazole following a single 150 mg oral dose were equal to plasma concentrations at both 4 and 24 hours post dose. In patients with fungal meningitis, Fluconazole concentrations in the CSF are approximately 80% of the corresponding plasma concentrations.


A single oral 150 mg dose of Fluconazole administered to 27 patients penetrated into vaginal tissue, resulting in tissue:plasma ratios ranging from 0.94 to 1.14 over the first 48 hours following dosing.


A single oral 150 mg dose of Fluconazole administered to 14 patients penetrated into vaginal fluid, resulting in fluid:plasma ratios ranging from 0.36 to 0.71 over the first 72 hours following dosing.

In normal volunteers, Fluconazole is cleared primarily by renal excretion, with approximately 80% of the administered dose appearing in the urine as unchanged drug. About 11% of the dose is excreted in the urine as metabolites.


The pharmacokinetics of Fluconazole are markedly affected by reduction in renal function. There is an inverse relationship between the elimination half-life and creatinine clearance. The dose of Fluconazole may need to be reduced in patients with impaired renal function. (See DOSAGE AND ADMINISTRATION.) A 3-hour hemodialysis session decreases plasma concentrations by approximately 50%.


In normal volunteers, Fluconazole administration (doses ranging from 200 mg to 400 mg once daily for up to 14 days) was associated with small and inconsistent effects on testosterone concentrations, endogenous corticosteroid concentrations, and the ACTH-stimulated cortisol response.

Clearance corrected for body weight was not affected by age in these studies. Mean body clearance in adults is reported to be 0.23 (17%) mL/min/kg.


In premature newborns (gestational age 26 to 29 weeks), the mean (%cv) clearance within 36 hours of birth was 0.180 (35%, N=7) mL/min/kg, which increased with time to a mean of 0.218 (31%, N=9) mL/min/kg six days later and 0.333 (56%, N=4) mL/min/kg 12 days later. Similarly, the half-life was 73.6 hours, which decreased with time to a mean of 53.2 hours six days later and 46.6 hours 12 days later.



Pharmacokinetics in Elderly


A pharmacokinetic study was conducted in 22 subjects, 65 years of age or older receiving a single 50 mg oral dose of Fluconazole. Ten of these patients were concomitantly receiving diuretics. The Cmax was 1.54 mcg/mL and occurred at 1.3 hours post dose. The mean AUC was 76.4 ± 20.3 mcg∙h/mL, and the mean terminal half-life was 46.2 hours. These pharmacokinetic parameter values are higher than analogous values reported for normal young male volunteers. Coadministration of diuretics did not significantly alter AUC or Cmax. In addition, creatinine clearance (74 mL/min), the percent of drug recovered unchanged in urine (0–24 hr, 22%), and the Fluconazole renal clearance estimates (0.124 mL/min/kg) for the elderly were generally lower than those of younger volunteers. Thus, the alteration of Fluconazole disposition in the elderly appears to be related to reduced renal function characteristic of this group. A plot of each subject's terminal elimination half-life versus creatinine clearance compared with the predicted half-life – creatinine clearance curve derived from normal subjects and subjects with varying degrees of renal insufficiency indicated that 21 of 22 subjects fell within the 95% confidence limit of the predicted half-life – creatinine clearance curves. These results are consistent with the hypothesis that higher values for the pharmacokinetic parameters observed in the elderly subjects compared with normal young male volunteers are due to the decreased kidney function that is expected in the elderly.



Drug Interaction Studies


Oral contraceptives

Oral contraceptives were administered as a single dose both before and after the oral administration of Fluconazole 50 mg once daily for 10 days in 10 healthy women. There was no significant difference in ethinyl estradiol or levonorgestrel AUC after the administration of 50 mg of Fluconazole. The mean increase in ethinyl estradiol AUC was 6% (range: −47 to 108%) and levonorgestrel AUC increased 17% (range: −33 to 141%).


In a second study, twenty-five normal females received daily doses of both 200 mg Fluconazole tablets or placebo for two, ten-day periods. The treatment cycles were one month apart with all subjects receiving Fluconazole during one cycle and placebo during the other. The order of study treatment was random. Single doses of an oral contraceptive tablet containing levonorgestrel and ethinyl estradiol were administered on the final treatment day (day 10) of both cycles. Following administration of 200 mg of Fluconazole, the mean percentage increase of AUC for levonorgestrel compared to placebo was 25% (range: –12 to 82%) and the mean percentage increase for ethinyl estradiol compared to placebo was 38% (range: –11 to 101%). Both of these increases were statistically significantly different from placebo.


A third study evaluated the potential interaction of once weekly dosing of Fluconazole 300 mg to 21 normal females taking an oral contraceptive containing ethinyl estradiol and norethindrone. In this placebo-controlled, double-blind, randomized, two-way crossover study carried out over three cycles of oral contraceptive treatment, Fluconazole dosing resulted in small increases in the mean AUCs of ethinyl estradiol and norethindrone compared to similar placebo dosing. The mean AUCs of ethinyl estradiol and norethindrone increased by 24% (95% C.I. range: 18–31%) and 13% (95% C.I. range: 8–18%), respectively, relative to placebo. Fluconazole treatment did not cause a decrease in the ethinyl estradiol AUC of any individual subject in this study compared to placebo dosing. The individual AUC values of norethindrone decreased very slightly (<5%) in 3 of the 21 subjects after Fluconazole treatment.


Cimetidine

Fluconazole 100 mg was administered as a single oral dose alone and two hours after a single dose of cimetidine 400 mg to six healthy male volunteers. After the administration of cimetidine, there was a significant decrease in Fluconazole AUC and Cmax. There was a mean ± SD decrease in Fluconazole AUC of 13% ± 11% (range: −3.4 to −31%) and Cmax decreased 19% ± 14% (range: −5 to −40%). However, the administration of cimetidine 600 mg to 900 mg intravenously over a four-hour period (from one hour before to 3 hours after a single oral dose of Fluconazole 200 mg) did not affect the bioavailability or pharmacokinetics of Fluconazole in 24 healthy male volunteers.


Antacid

Administration of Maalox® (20 mL) to 14 normal male volunteers immediately prior to a single dose of Fluconazole 100 mg had no effect on the absorption or elimination of Fluconazole.


Hydrochlorothiazide

Concomitant oral administration of 100 mg Fluconazole and 50 mg hydrochlorothiazide for 10 days in 13 normal volunteers resulted in a significant increase in Fluconazole AUC and Cmax compared to Fluconazole given alone. There was a mean ± SD increase in Fluconazole AUC and Cmax of 45% ± 31% (range: 19 to 114%) and 43% ± 31% (range: 19 to 122%), respectively. These changes are attributed to a mean ± SD reduction in renal clearance of 30% ± 12% (range: −10 to −50%).


Rifampin

Administration of a single oral 200 mg dose of Fluconazole after 15 days of rifampin administered as 600 mg daily in eight healthy male volunteers resulted in a significant decrease in Fluconazole AUC and a significant increase in apparent oral clearance of Fluconazole. There was a mean ± SD reduction in Fluconazole AUC of 23% ± 9%(range: −13 to −42%). Apparent oral clearance of Fluconazole increased 32% ± 17% (range: 16 to 72%). Fluconazole half-life decreased from 33.4 ± 4.4 hours to 26.8 ± 3.9 hours. (See PRECAUTIONS.)


Warfarin

There was a significant increase in prothrombin time response (area under the prothrombin time-time curve) following a single dose of warfarin (15 mg) administered to 13 normal male volunteers following oral Fluconazole 200 mg administered daily for 14 days as compared to the administration of warfarin alone. There was a mean ± SD increase in the prothrombin time response (area under the prothrombin time-time curve) of 7% ± 4% (range: −2 to 13%). (See PRECAUTIONS.) Mean is based on data from 12 subjects as one of 13 subjects experienced a 2-fold increase in his prothrombin time response.


Phenytoin

Phenytoin AUC was determined after 4 days of phenytoin dosing (200 mg daily, orally for 3 days followed by 250 mg intravenously for one dose) both with and without the administration of Fluconazole (oral Fluconazole 200 mg daily for 16 days) in 10 normal male volunteers. There was a significant increase in phenytoin AUC. The mean ± SD increase in phenytoin AUC was 88% ± 68% (range: 16 to 247%). The absolute magnitude of this interaction is unknown because of the intrinsically nonlinear disposition of phenytoin. (See PRECAUTIONS.)


Cyclosporine

Cyclosporine AUC and Cmax were determined before and after the administration of Fluconazole 200 mg daily for 14 days in eight renal transplant patients who had been on cyclosporine therapy for at least 6 months and on a stable cyclosporine dose for at least 6 weeks. There was a significant increase in cyclosporine AUC, Cmax, Cmin (24-hour concentration), and a significant reduction in apparent oral clearance following the administration of Fluconazole. The mean ± SD increase in AUC was 92% ± 43% (range: 18 to 147%). The Cmax increased 60% ± 48% (range: −5 to 133%). The Cmin increased 157% ± 96% (range: 33 to 360%). The apparent oral clearance decreased 45% ± 15% (range: −15 to −60%). (See PRECAUTIONS.)


Zidovudine

Plasma zidovudine concentrations were determined on two occasions (before and following Fluconazole 200 mg daily for 15 days) in 13 volunteers with AIDS or ARC who were on a stable zidovudine dose for at least two weeks. There was a significant increase in zidovudine AUC following the administration of Fluconazole. The mean ± SD increase in AUC was 20% ± 32% (range: −27 to 104%). The metabolite, GZDV, to parent drug ratio significantly decreased after the administration of Fluconazole, from 7.6 ± 3.6 to 5.7 ± 2.2.


Theophylline

The pharmacokinetics of theophylline were determined from a single intravenous dose of aminophylline (6 mg/kg) before and after the oral administration of Fluconazole 200 mg daily for 14 days in 16 normal male volunteers. There were significant increases in theophylline AUC, Cmax, and half-life with a corresponding decrease in clearance. The mean ± SD theophylline AUC increased 21% ± 16% (range: −5 to 48%). The Cmax increased 13% ± 17% (range: −13 to 40%). Theophylline clearance decreased 16% ± 11% (range: −32 to 5%). The half-life of theophylline increased from 6.6 ± 1.7 hours to 7.9 ± 1.5 hours. (See PRECAUTIONS.)


Terfenadine

Six healthy volunteers received terfenadine 60 mg BID for 15 days. Fluconazole 200 mg was administered daily from days 9 through 15. Fluconazole did not affect terfenadine plasma concentrations. Terfenadine acid metabolite AUC increased 36% ± 36% (range: 7 to 102%) from day 8 to day 15 with the concomitant administration of Fluconazole. There was no change in cardiac repolarization as measured by Holter QTc intervals. Another study at a 400 mg and 800 mg daily dose of Fluconazole demonstrated that Fluconazole taken in doses of 400 mg per day or greater significantly increases plasma levels of terfenadine when taken concomitantly. (See CONTRAINDICATIONS and PRECAUTIONS.)


Oral hypoglycemics

The effects of Fluconazole on the pharmacokinetics of the sulfonylurea oral hypoglycemic agents tolbutamide, glipizide, and glyburide were evaluated in three placebo-controlled studies in normal volunteers. All subjects received the sulfonylurea alone as a single dose and again as a single dose following the administration of Fluconazole 100 mg daily for 7 days. In these three studies, 22/46 (47.8%) of Fluconazole treated patients and 9/22 (40.1%) of placebo-treated patients experienced symptoms consistent with hypoglycemia. (See PRECAUTIONS.)


Tolbutamide

In 13 normal male volunteers, there was significant increase in tolbutamide (500 mg single dose) AUC and Cmax following the administration of Fluconazole. There was a mean ± SD increase in tolbutamide AUC of 26% ± 9% (range: 12 to 39%). Tolbutamide Cmax increased 11% ± 9% (range: –6 to 27%). (See PRECAUTIONS.)


Glipizide

The AUC and Cmax of glipizide (2.5 mg single dose) were significantly increased following the administration of Fluconazole in 13 normal male volunteers. There was a mean ± SD increase in AUC of 49% ± 13% (range: 27 to 73%) and an increase in Cmax of 19% ± 23% (range: −11 to 79%). (See PRECAUTIONS.)


Glyburide

The AUC and Cmax of glyburide (5 mg single dose) were significantly increased following the administration of Fluconazole in 20 normal male volunteers. There was a mean ± SD increase in AUC of 44% ± 29% (range: –13 to 115%) and Cmax increased 19% ± 19% (range: −23 to 62%). Five subjects required oral glucose following the ingestion of glyburide after 7 days of Fluconazole administration. (See PRECAUTIONS.)


Rifabutin

There have been published reports that an interaction exists when Fluconazole is administered concomitantly with rifabutin, leading to increased serum levels of rifabutin. (See PRECAUTIONS.)


Tacrolimus

There have been published reports that an interaction exists when Fluconazole is administered concomitantly with tacrolimus, leading to increased serum levels of tacrolimus. (See PRECAUTIONS.)


Cisapride

A placebo-controlled, randomized, multiple-dose study examined the potential interaction of Fluconazole with cisapride. Two groups of 10 normal subjects were administered Fluconazole 200 mg daily or placebo. Cisapride 20 mg four times daily was started after 7 days of Fluconazole or placebo dosing. Following a single dose of Fluconazole, there was a 101% increase in the cisapride AUC and a 91% increase in the cisapride Cmax. Following multiple doses of Fluconazole, there was a 192% increase in the cisapride AUC and a 154% increase in the cisapride Cmax . Fluconazole significantly increased the QTc interval in subjects receiving cisapride 20 mg four times daily for 5 days. (See CONTRAINDICATIONS and PRECAUTIONS.)


Midazolam

The effect of Fluconazole on the pharmacokinetics and pharmacodynamics of midazolam was examined in a randomized, crossover study in 12 volunteers. In the study, subjects ingested placebo or 400 mg Fluconazole on Day 1 followed by 200 mg daily from Day 2 to Day 6. In addition, a 7.5 mg dose of midazolam was orally ingested on the first day, 0.05 mg/kg was administered intravenously on the fourth day, and 7.5 mg orally on the sixth day. Fluconazole reduced the clearance of IV midazolam by 51%. On the first day of dosing, Fluconazole increased the midazolam AUC and Cmax by 259% and 150%, respectively. On the sixth day of dosing, Fluconazole increased the midazolam AUC and Cmax by 259% and 74%, respectively. The psychomotor effects of midazolam were significantly increased after oral administration of midazolam but not significantly affected following intravenous midazolam.


A second randomized, double-dummy, placebo-controlled, crossover study in three phases was performed to determine the effect of route of administration of Fluconazole on the interaction between Fluconazole and midazolam. In each phase the subjects were given oral Fluconazole 400 mg and intravenous saline; oral placebo and intravenous Fluconazole 400 mg; and oral placebo and IV saline. An oral dose of 7.5 mg of midazolam was ingested after Fluconazole/placebo. The AUC and Cmax of midazolam were significantly higher after oral than IV administration of Fluconazole. Oral Fluconazole increased the midazolam AUC and Cmax by 272% and 129%, respectively. IV Fluconazole increased the midazolam AUC and Cmax by 244% and 79%, respectively. Both oral and IV Fluconazole increased the pharmacodynamic effects of midazolam. (See PRECAUTIONS.)


Azithromycin

An open-label, randomized, three-way crossover study in 18 healthy subjects assessed the effect of a single 800 mg oral dose of Fluconazole on the pharmacokinetics of a single 1200 mg oral dose of azithromycin as well as the effects of azithromycin on the pharmacokinetics of Fluconazole. There was no significant pharmacokinetic interaction between Fluconazole and azithromycin.


Voriconazole

Voriconazole is a substrate for both CYP2C9 and CYP3A4 isoenzymes. Concurrent administration of oral Voriconazole (400 mg Q12h for 1 day, then 200 mg Q12h for 2.5 days) and oral Fluconazole (400 mg on day 1, then 200 mg Q24h for 4 days) to 6 healthy male subjects resulted in an increase in Cmax and AUCτ of voriconazole by an average of 57% (90% CI: 20%, 107%) and 79% (90% CI: 40%, 128%), respectively. In a follow-on clinical study involving 8 healthy male subjects, reduced dosing and/or frequency of voriconazole and Fluconazole did not eliminate or diminish this effect. Concomitant administration of voriconazole and Fluconazole at any dose is not recommended. Close monitoring for adverse events related to voriconazole is recommended if voriconazole is used sequentially after Fluconazole, especially within 24 h of the last dose of Fluconazole. (See PRECAUTIONS)



Microbiology


Mechanism of Action

Fluconazole is a highly selective inhibitor of fungal cytochrome P450 dependent enzyme lanosterol 14-α-demethylase. This enzyme functions to convert lanosterol to ergosterol. The subsequent loss of normal sterols correlates with the accumulation of 14-α-methyl sterols in fungi and may be responsible for the fungistatic activity of Fluconazole. Mammalian cell demethylation is much less sensitive to Fluconazole inhibition.



Activity In Vitro and In Clinical Infections


Fluconazole has been shown to be active against most strains of the following microorganisms both in vitro and in clinical infections.


Candida albicans

Candida glabrata (Many strains are intermediately susceptible)1

Candida parapsilosis

Candida tropicalis

Cryptococcus neoformans


The following in vitro data are available, but their clinical significance is unknown.


Fluconazole exhibits in vitro minimum inhibitory concentrations (MIC values) of 8 µg/mL or less against most (≥90%) strains of the following microorganisms, however, the safety and effectiveness of Fluconazole in treating clinical infections due to these microorganisms have not been established in adequate and well-controlled trials.


Candida dubliniensis

Candida guilliermondii

Candida kefyr

Candida lusitaniae


Candida krusei should be considered to be resistant to Fluconazole. Resistance in C. krusei appears to be mediated by reduced sensitivity of the target enzyme to inhibition by the agent.


There have been reports of cases of superinfection with Candida species other than C. albicans, which are often inherently not susceptible to Fluconazole (e.g., Candida krusei). Such cases may require alternative antifungal therapy.



1

In a majority of the studies, Fluconazole MIC90 values against C. glabrata were above the susceptible breakpoint (≥16 µg/mL). Resistance in Candida glabrata usually includes upregulation of CDR genes resulting in resistance to multiple azoles. For an isolate where the MIC is categorized as intermediate (16 to 32 µg/mL, see Table 1), the highest dose is recommended (see DOSAGE AND ADMINISTRATION). For resistant isolates, alternative therapy is recommended.

Susceptibility Testing Methods

Cryptococcus neoformans and filamentous fungi


No interpretive criteria have been established for Cryptococcus neoformans and filamentous fungi.



Candida species



Broth Dilution Techniques

Quantitative methods are used to determine antifungal minimum inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of Candida spp. to antifungal agents. MICs should be determined using a standardized procedure. Standardized procedures are based on a dilution method (broth)1 with standardized inoculum concentrations of Fluconazole powder. The MIC values should be interpreted according to the criteria provided in Table 1.



Diffusion Techniques

Qualitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of Candida spp. to an antifungal agent. One such standardized procedure2 requires the use of standardized inoculum concentrations. This procedure uses paper disks impregnated with 25 µg of Fluconazole to test the susceptibility of yeasts to Fluconazole. Disk diffusion interpretive criteria are also provided in Table 1.

The intermediate category is sometimes called Susceptible-Dose Dependent (SDD) and both categories are equivalent for Fluconazole.


Isolates of C. krusei are assumed to be intrinsically resistant to Fluconazole and their MICs and/or zone diameters should not be interpreted using this scale.

Fluconazole≤ 8.016–32≥64≥1915–18≤14

The susceptible category implies that isolates are inhibited by the usually achievable concentrations of antifungal agent tested when the recommended dosage is used. The intermediate category implies that an infection due to the isolate may be appropriately treated in body sites where the drugs are physiologically concentrated or when a high dosage of drug is used. The resistant category implies that isolates are not inhibited by the usually achievable concentrations of the agent with normal dosage schedules and clinical efficacy of the agent against the isolate has not been reliably shown in treatment studies.


Quality Control

Standardized susceptibility test procedures require the use of quality control organisms to control the technical aspects of the test procedures. Standardized Fluconazole powder and 25 µg disks should provide the following range of values noted in Table 2. NOTE: Quality control microorganisms are specific strains of organisms with intrinsic biological properties relating to resistance mechanisms and their genetic expression within fungi; the specific strains used for microbiological control are not clinically significant.

Activity In Vivo

Fungistatic activity has also been demonstrated in normal and immunocompromised animal models for systemic and intracranial fungal infections due to Cryptococcus neoformans and for systemic infections due to Candida albicans.


In common with other azole antifungal agents, most fungi show a higher apparent sensitivity to Fluconazole in vivo than in vitro. Fluconazole administered orally and/or intravenously was active in a variety of animal models of fungal infection using standard laboratory strains of fungi. Activity has been demonstrated against fungal infections caused by Aspergillus flavus and Aspergillus fumigatus in normal mice. Fluconazole has also been shown to be active in animal models of endemic mycoses, including one model of Blastomyces dermatitidis pulmonary infections in normal mice; one model of Coccidioides immitis intracranial infections in normal mice; and several models of Histoplasma capsulatum pulmonary infection in normal and immunosuppressed mice. The clinical significance of results obtained in these studies is unknown.


Oral Fluconazole has been shown to be active in an animal model of vaginal candidiasis.


Concurrent administration of Fluconazole and amphotericin B in infected normal and immunosuppressed mice showed the following results: a small additive antifungal effect in systemic infection with C. albicans, no interaction in intracranial infection with Cryptococcus neoformans, and antagonism of the two drugs in systemic infection with A. fumigatus. The clinical significance of results obtained in these studies is unknown.


Drug Resistance

Fluconazole resistance may arise from a modification in the quality or quantity of the target enzyme (lanosterol 14-α-demethylase), reduced access to the drug target, or some combination of these mechanisms.


Point mutations in the gene (ERG11) encoding for the target enzyme lead to an altered target with decreased affinity for azoles. Overexpression of ERG11 results in the production of high concentrations of the target enzyme, creating the need for higher intracellular drug concentrations to inhibit all of the enzyme molecules in the cell.


The second major mechanism of drug resistance involves active efflux of Fluconazole out of the cell through the activation of two types of multidrug efflux transporters; the major facilitators (encoded by MDR genes) and those of the ATP-binding cassette superfamily (encoded by CDR genes). Upregulation of the MDR gene leads to Fluconazole resistance, whereas, upregulation of CDR genes may lead to resistance to multiple azoles.


Resistance in Candida glabrata usually includes upregulation of CDR genes resulting in resistance to multiple azoles. For an isolate where the MIC is categorized as Intermediate (16 to 32 µg/mL), the highest Fluconazole dose is recommended.


Candida krusei should be considered to be resistant to Fluconazole. Resistance in C. krusei appears to be mediated by reduced sensitivity of the target enzyme to inhibition by the agent.


There have been reports of cases of superinfection with Candida species other than C. albicans, which are often inherently not susceptible to Fluconazole (e.g., Candida krusei). Such cases may require alternative antifungal therapy.



Indications and Usage for Fluconazole


Fluconazole is indicated for the treatment of:


  1. Vaginal candidiasis (vaginal yeast infections due to Candida).

  2. Oropharyngeal and esophageal candidiasis. In open noncomparative studies of relatively small numbers of patients, Fluconazole was also effective for the treatment of Candida urinary tract infections, peritonitis, and systemic Candida infections including candidemia, disseminated candidiasis, and pneumonia.

  3. Cryptococcal meningitis. Before prescribing Fluconazole for AIDS patients with cryptococcal meningitis, please see CLINICAL STUDIES section. Studies comparing Fluconazole to amphotericin B in non-HIV infected patients have not been conducted.


Prophylaxis


Fluconazole is also indicated to decrease the incidence of candidiasis in patients undergoing bone marrow transplantation who receive cytotoxic chemotherapy and/or radiation therapy.


Specimens for fungal culture and other relevant laboratory studies (serology, histopathology) should be obtained prior to therapy to isolate and identify causative organisms. Therapy may be instituted before the results of the cultures and other laboratory studies are known; however, once these results become available, anti-infective therapy should be adjusted accordingly.



Clinical Studies



Cryptococcal meningitis


In a multicenter study comparing Fluconazole (200 mg/day) to amphotericin B (0.3 mg/kg/day) for treatment of cryptococcal meningitis in patients with AIDS, a multivariate analysis revealed three pretreatment factors that predicted death during the course of therapy: abnormal mental status, cerebrospinal fluid cryptococcal antigen titer greater than 1:1024, and cerebrospinal fluid white blood cell count of less than 20 cells/mm3. Mortality among high risk patients was 33% and 40% for amphotericin B and Fluconazole patients, respectively (p=0.58), with overall deaths 14% (9 of 63 subjects) and 18% (24 of 131 subjects) for the 2 arms of the study (p=0.48). Optimal doses and regimens for patients with acute cryptococcal meningitis and at high risk for treatment failure remain to be determined. (Saag, et al. N Engl J Med 1992; 326:83–9.)



Vaginal candidiasis


Two adequate and well-controlled studies were conducted in the U.S. using the 150 mg tablet. In both, the results of the Fluconazole regimen were comparable to the control regimen (clotrimazole or miconazole intravaginally for 7 days) both clinically and statistically at the one month post-treatment evaluation.


The therapeutic cure rate, defined as a complete resolution of signs and symptoms of vaginal candidiasis (clinical cure), along with a negative KOH examination and negative culture for Candida (microbiologic eradication), was 55% in both the Fluconazole group and the vaginal products group.

Approximately three-fourths of the enrolled patients had acute vaginitis (<4 episodes/12 months) and achieved 80% clinical cure, 67% mycologic eradication, and 59% therapeutic cure when treated with a 150 mg Fluconazole tablet administered orally. These rates were comparable to control products. The remaining one-fourth of enrolled patients had recurrent vaginitis (≥4 episodes/12 months) and achieved 57% clinical cure, 47% mycologic eradication, and 40% therapeutic cure. The numbers are too small to make meaningful clinical or statistical comparisons with vaginal products in the treatment of patients with recurrent vaginitis.


Substantially more gastrointestinal events were reported in the Fluconazole group compared to the vaginal product group. Most of the events were mild to moderate. Because Fluconazole was given as a single dose, no discontinuations occurred.

Pediatric Studies


Oropharyngeal candidiasis

An open-label, comparative study of the efficacy and safety of Fluconazole (2–3 mg/kg/day) and oral nystatin (400,000 I.U. 4 times daily) in immunocompromised children with oropharyngeal candidiasis was conducted. Clinical and mycological response rates were higher in the children treated with Fluconazole.


Clinical cure at the end of treatment was reported for 86% of Fluconazole treated patients compared to 46% of nystatin treated patients. Mycologically, 76% of Fluconazole treated patients had the infecting organism eradicated compared to 11% for nystatin treated patients.
