Venac (0.1%) 5ml Eye Drops

Nepafenac, a non-steroidal anti-inflammatory drug (NSAID), primarily acts by inhibiting the cyclooxygenase (COX) enzymes, COX-1 and COX-2, which are involved in the synthesis of prostaglandins. When administered in the form of eye drops, nepafenac penetrates the cornea and undergoes rapid metabolism to amfenac, its active form. Amfenac selectively blocks the COX enzymes, particularly COX-2, which is responsible for the production of inflammatory mediators such as prostaglandins and thromboxanes. By inhibiting the production of these inflammatory substances, nepafenac helps reduce pain, inflammation, and ocular discomfort associated with various eye conditions. This mechanism of action makes nepafenac effective in managing postoperative inflammation and pain following cataract surgery or other ocular procedures.
