Pharmacology

Fluconazole is a triazole antifungal that is used to treat fungal infections. It's a strong inhibitor of cytochrome P-450-dependent enzymes in fungi. The ergosterol synthesis is carried out by the Cytochrome P-450 enzyme system, which is an important component of the fungal cell membrane.
