Aqueous, oil, and ointment formulations of ketorolac: efficacy against prostaglandin E2-induced ocular inflammation and safety: A technical note

Summary and ConclusionsThe efficacy of aqueous, oil, and ointment formulations of ketorolac against PGE2-induced ocular inflammation in rabbits was evaluated, with monitoring of blinking rate and PMN and protein migration in tear fluid, following topical PGE2 instillation. Ketorolac ophthalmic formulations protected the eye against inflammatory insult. Chronic topical administration of formulations for 10 days into rats' eyes did not lead to any appreciable gastrointestinal ulceration, which indicates that the formulations are safe for long-term use.
