ZYLET (loteprednol etabonate)

Ophthalmology Approved 2004-12-14

Zylet is an ophthalmic suspension that helps patients with inflammatory eye conditions when a bacterial infection is either present or likely to occur. This medication combines a corticosteroid to reduce swelling and redness with an antibiotic to address common eye pathogens. It is used for various issues affecting the front of the eye, including severe allergies, certain types of keratitis, and injuries resulting from burns or foreign objects.

How ZYLET Works

This medication works by inducing inhibitory proteins called lipocortins, which block the release of arachidonic acid to prevent the production of inflammatory mediators like prostaglandins and leukotrienes. By inhibiting these pathways, the drug reduces swelling, capillary dilation, and scar formation in ocular tissues. Additionally, the aminoglycoside component provides targeted action against susceptible bacteria to manage or prevent superficial infections.
