Ketorin (Ketotolac) is rapidly and almost completely absorbed after oraldosing. Peak plasma concentration reaches with 30-60 minutes after oraldosing. Mean plasma half-life is 5.4 hours. Following IV administrationof 15 or 30 mg doses of Ketorolac injection peak plasma concentrationreaches within 1 or 3 minutes. Onset of analgesic action is 10 minutesafter IM administration.
Ketorin (Ketorolac) is indicated for the short-term management ofmoderate to severe pain. Major indications are

In Keeping with most ofthe currently used NSAIDs, Ketorolac preferentially inhibits theconstitutive isoenzyme cyclooxygenase-1 rather than the induclible form,cyclooxygenase-2.
