🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Nepafenac is a prodrug that penetrates the cornea and is converted by ocular tissue hydrolases to amfenac, a potent inhibitor of cyclooxygenase-1 and cyclooxygenase-2 enzymes. This inhibition reduces the synthesis of prostaglandins, which are mediators of inflammation and pain.
