KETOCONAZOLE- ketoconazole_cream
Function and Efficacy
When Ketoconazole Cream 2% was applied dermally to intact or abraded skin of Beagle dogs for 28 consecutive days at a dose of 80 mg, there were no detectable plasma levels using an assay method having a lower detection limit of 2 ng/ml. After a single topical application to the chest, back and arms of normal volunteers, systemic absorption of ketoconazole was not detected at the 5 ng/ml level in blood over a 72-hour period. Two dermal irritancy studies, a human sensitization test, a phototoxicity study and a photoallergy study conducted in 38 male and 62 female volunteers showed no contact sensitization of the delayed hypersensitivity type, no irritation, no phototoxicity and no photoallergenic potential due to Ketoconazole Cream 2%. Microbiology: in vitro Trichophyton rubrum, T. mentagrophytes, T. tonsurans, Microsporum canis, M. audouini, M. gypseum and Epidermophyton floccosum; Candida albicans, Malassezia ovale (Pityrosporum ovale) C. tropicalis; Malassezia furfur (Pityrosporum orbiculare) Mode of Action: In vitro.

Adverse Reactions
During clinical trials 45 (5.0%) of 905 patients treated with Ketoconazole Cream 2% and 5 (2.4%) of 208 patients treated with placebo reported side effects consisting mainly of severe irritation, pruritus and stinging. One of the patients treated with Ketoconazole Cream developed a painful allergic reaction. In worldwide postmarketing experience, rare reports of contact dermatitis have been associated with Ketoconazole Cream or one of its excipients, namely sodium sulfite or propylene glycol.
Precautions
Ketoconazole Cream 2% is contraindicated in persons who have shown hypersensitivity to the active or excipient ingredients of this formulation.
Special Population Medication
Ketoconazole has been shown to be teratogenic (syndactylia and oligodactylia) in the rat when given orally in the diet at 80 mg/kg/day, (10 times the maximum recommended human oral dose). However, these effects may be related to maternal toxicity, which was seen at this and higher dose levels. There are no adequate and well-controlled studies in pregnant women. Ketoconazole should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Other Information
Ketoconazole Cream 2% is not for ophthalmic use. Ketoconazole Cream 2% contains sodium sulfite anhydrous, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people.
