🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Natamycin binds to ergosterol in the fungal cell membrane, forming pores that increase membrane permeability. This leads to leakage of essential intracellular components such as potassium and other ions, resulting in fungal cell death. It is fungicidal against many filamentous fungi and some yeasts.
