I-Nak Eye Drop contains Nepafenac 0.1% w/v, a non-steroidal anti-inflammatory drug (NSAID) indicated for the management of postoperative inflammation and pain associated with cataract surgery. Nepafenac is a prodrug that, upon ocular penetration, is converted to amfenac, which inhibits cyclooxygenase enzymes COX-1 and COX-2, thereby reducing the synthesis of prostaglandins responsible for inflammation and pain. I-Nak Eye Drop is administered topically, allowing targeted delivery to ocular tissues with minimal systemic absorption. It is typically prescribed as one drop three times daily starting one day prior to surgery and continued for up to two weeks postoperatively, or as directed by a healthcare professional. The formulation is sterile, preservative-free, and designed to minimize ocular irritation. Common adverse effects may include transient burning or stinging upon instillation, blurred vision, or conjunctival hyperemia. Caution is advised in patients with known hypersensitivity to nepafenac or other NSAIDs. Use during pregnancy and lactation should be under medical supervision. I-Nak Eye Drop should not be used in patients with active ocular infections or corneal epithelial defects. Proper administration technique and adherence to prescribed dosage are essential to optimize therapeutic outcomes and minimize complications.
