Ketsenz LS Eye Drop contains Ketorolac 0.4% w/v, a nonsteroidal anti-inflammatory drug (NSAID) indicated for the management of ocular inflammation and pain. Ketorolac acts by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), thereby reducing the synthesis of prostaglandins responsible for inflammation, pain, and edema. This ophthalmic solution is primarily used to alleviate postoperative inflammation following cataract surgery, as well as to relieve symptoms associated with allergic conjunctivitis such as itching and redness. Ketsenz LS Eye Drop is administered topically to the affected eye(s), providing targeted anti-inflammatory effects with minimal systemic absorption. It is contraindicated in patients with hypersensitivity to ketorolac or other NSAIDs, and caution is advised in individuals with a history of bleeding disorders or corneal epithelial defects. Common adverse effects may include transient burning or stinging upon instillation, blurred vision, and increased lacrimation. Prolonged use should be avoided to minimize the risk of corneal complications. Ketsenz LS Eye Drop should be used under the supervision of an ophthalmologist, with adherence to recommended dosage and duration to ensure optimal therapeutic outcomes while minimizing potential adverse effects.
