Usage

What is Nepafenac?

Nepafenac is a nonsteroidal anti-inflammatory drug (NSAID), usually sold as a prescription eye drop 0.1% solution or 0.3% solution. Nepafenac is used to treat pain and inflammation associated with cataract surgery. Nepafenac is a prodrug of amfenac, an inhibitor of COX-1 and COX-2 activity, thought to be a prodrug of amfenac after conversion by ocular tissue hydrolases after penetration via the cornea. Like other NSAIDs, is thought to inhibit cyclooxygenase action. In the European Union nepafenac is also indicated for the reduction in the risk of postoperative macular edema associated with cataract surgery in people with diabetes.
