摘要

This lecture will familiarize you with the use of some new drugs for common dermatologic diseases and will also review the use of some commonly prescribed drugs for newer dermatologic diseases. Itraconazole (Sporanox~(R), Janssen Pharmaceuticals, 100capsules and 10 mg/ml oral solution) is a member of the azole family of antifungal agents. Imidazoles (thiabendazole, clotrimazole, ketaconazole, miconazole and enilconazole) and triazoles (itraconazole and fluconazole) make up this family of drugs. Allazoles are potent inhibitors of ergosterol synthesis (a main membrane lipid of fungi) via inhibition of a microsomal cytochrome P450 enzyme (14 a sterol demethylase). Since mammalian cytochrome P450 is involved in glucocorticoid and sex hormone synthesis(androgens), depending on which azole, the dog's cortisol and androgen levels may decrease during therapy. This is more of a potential problem w/ketaconazole then w/itraconazole (ITZ) because ITZ is more selective for the fungal enzyme than the mammalian form.
