Nepafenac is a non-steroidal anti-inflammatory drug (NSAID), usually sold as a prescription eye drop (0.1% solution. Nepafenac is manufactured by Alcon as Nevanac. It is used to treat pain and inflammation associated with cataract surgery. The usual dose is 1 drop in each affected eye beginning 1 day prior to cataract surgery, continued on the day of surgery and through the first 2 weeks of the postoperative period. Its side effects may include decreased visual acuity, a feeling that something is in the eye, increased eye pressure or a sticky sensation, as well as other effects.

How to use
Nepafenac shows significantly greater ocular bioavailability and amfenac demonstrated greater potency at COX-2 inhibition than ketorolac or bromfenac. Nepafenac exhibits only weak COX-1 inhibitory activity with IC50 of 64.3 mM. Nepafenac inhibits prostaglandin synthesis in the iris/ciliary body (85-95%) and the retina/choroid (55%) in rabbits. Nepafenac (0.5%) produces 65% reduction in retinal edema which is correlated with 62% inhibition of blood-retinal barrier breakdown. Nepafenac (0.5%) significantly inhibits (46%) blood-retinal barrier breakdown concomitant with near total suppression of PGE2 synthesis (96%). Nepafenac significantly inhibits retinal prostaglandin E(2), superoxide, cyclooxygenase-2, and leukostasis within retinal microvessels in insulin-deficient diabetic rats, without affecting vascular endothelial growth factor (VEGF) and nitric oxide (NO). Nepafenac significantly inhibits the number of transferase-mediated dUTP nick-end labeling-positive capillary cells, acellular capillaries, and pericyte ghosts in diabetic rats. Nepafenac results in significantly less choroidal neovascularization and significant less ischemia-induced retinal neovascularization in mice compare to control. Nepafenac also blunts the increase in VEGF mRNA in the retina induced by ischemia. Nepafenac delays the progression of malignancy as well as reduces weight in an ocular and metastatic animal model of uveal melanoma.
