Voriconazole

Overview

Voriconazole is a potent antifungal medication commonly used to treat severe fungal infections in pets, particularly in dogs and cats. It belongs to the triazole class of antifungals and works by inhibiting the growth of fungi.

How It Works

Voriconazole inhibits the fungal cytochrome P450 enzyme, disrupting the formation of ergosterol, an essential component of fungal cell membranes. This action hinders the growth and replication of fungal cells, leading to their eventual death.

• Aspergillosis

• Severe fungal infections in pets with compromised immune systems
