Randomized Controlled Trial Clinical TrialRecovery from outpatient laparoscopic tubal ligation is not improved by preoperative administration of ketorolac or ibuprofen.
The analgesic efficacy of a single dose of ketorolac or ibuprofen given preoperatively was assessed in healthy outpatients undergoing general anesthesia for laparoscopic tubal ligation. Fifty patients were randomized to receive either ketorolac 60 mg intravenously (i.v.), ibuprofen 800 mg orally, or placebo in a double-blind manner. Anesthesia was induced with fentanyl 2 micrograms/kg, thiopental 5 mg/kg, and either vecuronium 0.1 mg/kg or succinylcholine 1.5 mg/kg i.v. and was maintained with nitrous oxide 67% in oxygen and isoflurane. ⋯ The dose of parenteral morphine required in the PACU was not different between the control (7 +/- 1.2 mg), ibuprofen (5.7 +/- 1.4 mg), and ketorolac (6.1 +/- 1.4 mg) groups. There was no difference between groups in terms of pain visual analog scale (VAS) scores, fatigue VAS scores, recovery times, or the incidence of postoperative nausea and vomiting. The preoperative administration of either parenteral ketorolac or oral ibuprofen did not decrease postoperative pain or side effects when compared to placebo in this outpatient population.

Randomized Controlled Trial Clinical Trial
Evaluation of the antipyretic effect of ketorolac, acetaminophen, and placebo in endotoxin-induced fever.
The authors studied the antipyretic effect of three intramuscular doses of ketorolac (15, 30, and 60 mg), acetaminophen 650 mg PO, and placebo in healthy male volunteers using an endotoxin-induced fever model. In this double-blind, double-dummy, parallel study, subjects were assigned randomly with equal probability to one of the above treatment groups. Thirty minutes after study medication administration, a 20 unit per kilogram dose of reference standard endotoxin (RSE) was administered intravenously, and temperature was determined every 15 minutes for an 8-hour period. ⋯ Furthermore, the 30 mg intramuscular dose of ketorolac demonstrated approximately the same antipyretic activity as the 650 mg oral dose of acetaminophen, and there was a statistically significant dose response across the three ketorolac doses studied (P < .0001). The majority of side effects reported during this study were symptoms associated with fever, including chills, headache, myalgia, and dizziness, all of which are effects of RSE. The frequency of side effects tended to be less in the treatment groups with the greatest antipyretic activity.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial[Treatment of tumor pain with flupirtine. Results of a double-blind study versus tramadol].
In a multicentric double-blind trial, flupirtine was compared with tramadol in the treatment of cancer pain. ⋯ Initially comparable in the two groups, pain was more markedly reduced after four weeks of treatment with flupirtine than after tramadol, the need for additional analgesic drugs also being less in the flupirtine group. The final general assessment by the attending doctors of the results achieved was "good" to "very good" in 63% of the patients on flupirtine, and in 46% of those on tramadol. Undesired effects were observed in 6% of the flupirtine patients and in 19% of those taking tramadol.

Randomized Controlled Trial Comparative Study Clinical Trial
A multiple-dose, double-blind comparison of intramuscularly and orally administered ketorolac tromethamine and Ketogan in patients with pain following orthopaedic surgery.
In this multiple-dose, double-blind study 100 patients with moderate, severe or very severe pain following orthopaedic surgery were randomly assigned to receive ketorolac, a non-steroidal anti-inflammatory drug with potent analgesic properties (10 mg), or the standard regimen of Ketogan (a combination product containing the narcotic analgesic, ketobemidone, plus a spasmolytic agent) by intramuscular injection every 1-6 h as needed for pain. When patients were able to tolerate an oral diet and were expected to respond to oral analgesic medication, based on overall pain sensitivity, they were switched to oral doses of the same medication every 4-6 h as needed. A maximum of four daily doses of medication was allowed for up to 10 days. ⋯ There were no statistically significant differences between ketorolac and Ketogan. The results show that 10-mg doses of ketorolac in intramuscular injections followed by 10-mg doses of oral ketorolac are as effective as Ketogan for the treatment of pain following orthopaedic surgery. Ketorolac appears to be better tolerated than Ketogan since significantly fewer patients reported adverse events (P = 0.004) when taking ketorolac.

Randomized Controlled Trial Multicenter Study Clinical Trial
Evaluation of intravenous ketorolac administered by bolus or infusion for treatment of postoperative pain. A double-blind, placebo-controlled, multicenter study.
Ketorolac is a nonsteroidal analgesic that may provide postoperative analgesia without opioid-related side effects. This double-blind, randomized, multicenter study evaluated the analgesic efficacy and safety of intravenous ketorolac in 207 patients during the first 24 h after major surgery. ⋯ It is concluded that intravenous boluses or infusions of ketorolac in conjunction with PCA morphine provide effective, safe analgesia after major surgery and improve on the response to PCA morphine alone.
