Fluconazole (INN) (IPA: ) is a triazoleantifungal drug used in the treatment and prevention of superficial and systemic fungal infections. It is commonly marketed under the trade name Diflucan (Pfizer).
Pharmacology
Mode of action
Like other imidazole- and triazole-class antifungals, fluconazole inhibits the fungal cytochrome P450 enzyme 14α-demethylase. Mammalian demethylase activity is much less sensitive to fluconazole than fungal demethylase. This inhibition prevents the conversion of lanosterol to ergosterol, an essential component of the fungal cell wall, and subsequent accumulation of 14α-methyl sterols.Pfizer Australia Pty Ltd.

Fluconazole is primarily fungistatic, however may be fungicidal against certain organisms in a dose-dependent manner.
