Action
Natamycin, a tetraene polyene antifungal antibiotic with predominantly fungicidal activity, is derived from Streptomyces natalensis. It binds to the sterol moiety of the fungal cell membrane and alters the membrane permeability, thereby allowing the depletion of essential cellular contents.
Absorption: Not expected to be absorbed systemically (ophthalmic). Distribution: Adheres onto cornea; retained in conjunctival fornices; does not produce effective intraocular fluid levels. |
Storage
Ophthalmic: Store between 2-24°C. Do not freeze. Protect from excessive heat and light.
