Mechanism of Action

Voriconazole is a triazole antifungal agent which inhibits cytochrome P450-dependent enzymes thereby inhibiting ergosterol synthesis in fungal cell membranes. It has a broad spectrum of activity against all Candida species (including strains resistant to fluconazole) ,Aspergillus spp., Scedosporium spp., and Fusarium spp. Absorption: Rapidly and completely absorbed from GI tract. Bioavailability: 96% (oral). Peak plasma concentration: 1-2 hr. Food decreases oral absorption. Distribution: Protein binding: 58%; diffuses into CSF. Metabolism: Saturable metabolism. Metabolised by P450 isoenzyme CYP2C19, CYP2C9 and CYP3A4 to inactive metabolites. Excretion: Excreted in urine (80%).
