🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively inhibiting the fungal enzyme squalene epoxidase, which is a key step in the biosynthesis of ergosterol. Ergosterol is an essential component of the fungal cell membrane. Inhibition leads to a deficiency of ergosterol and accumulation of squalene, which disrupts the cell membrane and results in fungal cell death.
