🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Natamycin binds to ergosterol, a key component of the fungal cell membrane. This binding creates pores in the membrane, leading to leakage of essential cellular ions and molecules, which results in fungal cell death. It is fungicidal against many filamentous fungi and yeasts.
