Fluconazole

Generic Name (active ingredient): Fluconazole
Brand Name: Fluconazole, Diflucan

Fluconazole is a synthetic antifungal medication from the triazoles group, mainly intended for treatment of candidiasis and other mycoses.

How does the medication work?
Fluconazole possesses a highly specific effect, inhibiting the enzyme activity of fungi that are dependent on cytochrome P450. It suppresses the conversion of fungi cells' lanosterol into ergosterol, increases the permeability of cell membrane, violates its growth and replication. Fluconazole, being highly selective for fungal cytochrome P450, practically does not inhibit these enzymes in the body and does not have anti-androgenic activity. The medication is active in opportunistic mycoses, including those caused by Candida spp. (including generalized forms of candidiasis in the background of immunosuppression), Cryptococcus neoformans and Coccidioides immitis (including intracranial infection), Microsporum spp. and Trichophyton spp; in endemic mycosis caused by Blastomyces dermatidis, Histoplasma capsulatum (including with immunosuppression).
