Benzalkonium Chloride + Natamycin is primarily used as a potent antifungal agent for treating fungal eye infections.
Secondary applications of this combination include the use of Benzalkonium chloride as an antimicrobial preservative in various products like antibacterial soaps, sanitisers, and cleaning agents.
Eye irritation
Discomfort or stinging sensation in the eyes
Temporary blurred vision
Possible allergic reactions such as rash, itching, and swelling
Severe dizziness
Benzalkonium Chloride + Natamycin is a combination of an antimicrobial and an antifungal.
Benzalkonium chloride is a quaternary ammonium compound. It works by disrupting the cellular membrane of bacteria. This alters the cell's permeability, causing leakage of essential cellular contents and deactivating enzymes responsible for regulating respiratory and metabolic activities in cells.
Natamycin is a naturally occurring antifungal agent. It works by binding to ergosterol, a crucial component of fungal cell membranes. This disrupts the membrane integrity, leading to leakage of cellular contents, inhibiting fungal growth, and eventually causing cell death.
