Randomized Controlled Trial Comparative Study Clinical TrialKetorolac tromethamine as compared with morphine sulfate for treatment of postoperative pain.
Ketorolac tromethamine, a nonnarcotic, prostaglandin synthesis-inhibiting analgesic, was compared with morphine sulfate for relief of moderate to severe postoperative pain. The 155 patient participants received single intramuscular doses of either ketorolac, 10, 30, or 90 mg, or morphine, 6 or 12 mg, administered in a double-blind, randomized fashion. Pain scores (verbal and visual analog) were recorded at baseline and assessed at 30 minutes and then hourly to 6 hours. ⋯ There were no serious side effects reported. The only side effect reported in more than 3% of patients was 8% somnolence with morphine. This study shows ketorolac to be a safe and effective analgesic for relief of postoperative pain.
