🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a prodrug that rapidly penetrates the cornea and is converted by ocular tissue hydrolases to amfenac, a potent non-steroidal anti-inflammatory drug. Amfenac inhibits the cyclooxygenase enzymes COX-1 and COX-2, thereby blocking the synthesis of prostaglandins and other inflammatory mediators. This reduces ocular inflammation, pain, and vascular permeability.
