Application
Natamycin is an antifungal drug for topical ophthalmic administration. It is a tetraene polyene antibiotic derived from Streptomyces natalensis. It possesses in vitro activity against a variety of yeast and filamentous fungi, including Candida, Aspergillus, Cephalosporium, Fusarium and Penicillium. Although the activity against fungi is dose-related, natamycin is predominantly fungicidal. Natamycin is not effective in vitro against gram-positive or gram-negative bacteria. Topical administration appears to produce effective concentrations of natamycin within the corneal stroma but not in intraocular fluid.
Description
Natamycin is a polyene amphoteric macrolide antibiotic with antifungal properties. Natamycin exerts its antifungal effects by binding to sterols in the fungal cell membrane thereby increasing membrane permeability. This leads to a leakage and loss of essential cellular constituents. Following ocular application, natamycin is retained in the conjunctival fornices and attains effective concentrations within the corneal stroma where it exerts its effect.
