Olopat KT Eye Drop BAK Free is a combination ophthalmic solution containing Ketorolac tromethamine 0.4% w/v and Olopatadine hydrochloride 0.1% w/v, formulated without benzalkonium chloride (BAK) to minimize ocular surface irritation. Ketorolac, a nonsteroidal anti-inflammatory drug (NSAID), provides effective inhibition of cyclooxygenase enzymes, thereby reducing inflammation, pain, and ocular discomfort associated with allergic conjunctivitis and postoperative inflammation. Olopatadine, a selective histamine H1 receptor antagonist with mast cell stabilizing properties, offers rapid relief from allergic symptoms such as itching, redness, and swelling by preventing histamine release and subsequent inflammatory mediator activity. The BAK-free formulation enhances patient tolerability, particularly for individuals with sensitive eyes or those requiring prolonged therapy. Olopat KT Eye Drop is indicated for the treatment of allergic conjunctivitis, seasonal allergic conjunctivitis, and ocular inflammation where both anti-inflammatory and anti-allergic effects are desired. It is suitable for adults and pediatric patients above two years of age. Administration should follow ophthalmic guidelines, typically one drop in the affected eye(s) two to three times daily, as directed by a healthcare professional. Caution is advised in patients with hypersensitivity to any component, and contact lens use should be avoided during treatment. This combination therapy offers a comprehensive approach to managing ocular allergy and inflammation with improved patient comfort.
