Meperidine-Ketorolac Combination Provides Better Analgesia than Meperidine Alone in Postoperative Patients.

Adding ketorolac to meperidine reduced postoperative pain, reduced patient daily opioid requirement, increased patient satisfaction with pain relief, without increasing the frequency of side effects. Therefore, IV ketorolac addition to opioids may be a reasonable option in multimodal analgesic protocol.
