Total cytochrome P-450, and the activities of aminopyrine N -demethylase, aniline p -hydroxylase and 7-ethoxycoumarin O -deethylase, after repeated administration of griseofulvin (100 mg/kg orally daily for 5 days) were examined. When suggestions are available use up and down arrows to review and ENTER to select. An alternative to Study I is to incorporate plasma sampling for the measurement of griseofulvin and its metabolite(s) into Study 2 using population pharmacokinetics for analysis. Acute effects of griseofulvin on the pharmacokinetics and pharmacodynamics of warfarin in rats. *Should be administered with a fatty meal to maximize absorptionFollowing absorption from the gastrointestinal tract, Oral absorption of griseofulvin is limited by its poor water solubility. Date of first authorisation/renewal of the authorisationStart typing to retrieve search suggestions. Consideration should be given that such patients may also have a degree of hepatic impairment, see section 4.4.The dosage form, film-coated tablet, is only suitable for children of an age to swallow the tablet.The usual dose in 10 mg / Kg bodyweight / day, in divided doses.The duration of theapy depends upon the thickness of keratin at the site of infection, and the clinical response. The use of griseofulvin is not justified in the treatment of minor or trivial infections that will respond to topical therapy.Before prescribing Griseofulvin Tablets, consideration should be given to national and/or local guidance on the appropriate use of antifungals. Women of childbearing potential have to use effective contraception during (and up to 4 weeks after) treatment (see section 4.5) in respect of effect on oral contraceptives, and contraceptive precautions.It is unknown if griseofulvin is excreted in breast milk, but the possibility does exist. Absorption of griseofulvin from the gastrointestinal tract is variable and incomplete, but is enhanced by reducing the particle size or when given with a fatty meal. The penetration of griseofulvin to its site of action was investigated in the rat using subepidermal blisters induced by suction as a model.

Griseofulvin was administered iv at a dose of 20 mg/kg after which blood, suction blister fluid (SBF), and skin tissue were sampled over a 300-min time period. Patients should therefore be cautioned not to drive or operate machines until they are sure they are not affected.The following frequencies are used for the description of the occurrence of undesirable effects:Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.Headache and gastric discomfort are the most common effects on starting treatment, but usually disappear as treatment is continued.Rare: leucopenia, neutropenia, anaemia-these usually resolve on therapy cessationUncommon: impaired co-ordination, peripheral neuropathy, confusion, dizziness, drowsiness, insomnia, irritability.Common: diarrhoea, vomiting, nausea, gastric discomfortUncommon: toxic epidermal necrolysis, erethema multiforme, photosensitivity on exposure to intense natural or artifical sunlight.Rare: precipitation of Systemic Lupus Eryhthematosus, bullous reactions including Lyell's syndrome, urticarial reactions, skin rashes.Very rare: alteration in liver function tests, with elevation to more than three times upper normal limit, intrahepatic cholecstasis, hepatitis.The likely symptoms of any overdose would be nausea, nomiting, headache, numbness and tingling, confusion, and vertigo. The remainder of the dose, principally as metabolites, is excreted in bile and faeces.Griseofulvin can induce aneuploidy and meiotic delay in mouse oocytes following oral administration of high doses, i.e. 1 2 4 7 9 13. Common side effects include allergic reactions, nausea, diarrhea, headache, trouble sleeping, and feeling tired. The effects in mice may be due to a species specific effect on porphyrin metabolism.Polypropylene (PP) tablet container with linear low density polyethylene (LLDPE) screw closure.Any unused product or waste material should be disposed of in accordance with local requirements.6-9 The Square, Regus Stockley Business Park, Uxbridge, UB11 1FW, UKTo bookmark a medicine you must sign up and log in.To view the changes to a medicine you must sign up and log in. There is selective deposition of griseofulvin in newly formed keratin of hair, skin, and nails, which gradually moves to the surface of these appendages.Griseofulvin undergoes metabolism to inactive metabolites, principally 6- desmethylgriseofulvin, or its glucuronide conjugate.The terminal plasma half life ranges from 9.5-21 hours, with considerable intersubject variability. Because it is also deposited in keratin precursor cells, new hair or nail growth is resistant to infection. Side effects are infrequent but include hypersensitivity rash, urticaria, nausea, vomiting, diarrhea, headache, fatigue, proteinuria, and leukopenia.
