Overview
Posaconazole is a broad-spectrum triazole antifungal medication used in veterinary medicine to treat a variety of serious fungal infections in pets, primarily dogs and cats. Its efficacy in combating resistant fungal strains makes it a critical tool in veterinary pharmacology.
How It Works
Posaconazole works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes. This inhibition disrupts the cell membrane formation, leading to increased permeability and ultimately the death of the fungal cell.
