Mechanism of action

Posaconazole is a triazole antifungal that selectively inhibits the cytochrome P450-dependent enzyme lanosterol 14α-demethylase in fungi. This blocks the synthesis of ergosterol, an essential component of the fungal cell membrane, leading to membrane instability and fungal cell death. The delayed-release formulation improves bioavailability and allows for more consistent plasma concentrations.
