Nepafenac is a nonsteroidal anti-inflammatory prodrug (NSAID). After instillation in the eye, it penetrates the cornea and is converted by ocular tissue hydrolase to Amfenac, a potent nonsteroidal anti-inflammatory drug. Amfenac is thought to inhibit the action of the cyclooxygenase enzyme, which is required for prostaglandin synthesis.
