Overview

Voriconazole is a second-generation, broad-spectrum triazole antifungal agent used to treat serious fungal infections, particularly in immunocompromised patients. It is effective against invasive aspergillosis, candidemia (including esophageal and deep tissue Candida infections), coccidioidomycosis, histoplasmosis, penicilliosis, and infections caused by Scedosporium and Fusarium species. Voriconazole works by inhibiting the fungal cytochrome P450 enzyme 14-alpha-lanosterol demethylase (CYP51), which blocks the conversion of lanosterol to ergosterol—a critical component of the fungal cell membrane—thereby disrupting membrane synthesis and function. This action limits fungal growth (fungistatic effect) and allows the host immune system to clear infection[1][3][4][5]. Developed originally by Pfizer as Vfend, it is available in oral tablet, oral suspension, and intravenous formulations.
