The effectiveness of 100 and 200 mg etodolac (Ultradol), aspirin, and placebo in patients with pain following oral surgery

Abstract

The analgesic efficacy of etodolac (Ultradol) was evaluated in 168 patients experiencing moderate to severe pain following oral surgery. The patients were given either etodolac 100 mg, etodolac 200 mg, aspirin 650 mg, or placebo. There was a minimum of forty patients in each drug group. Patients recorded pain intensity and pain relief at½hour and then hourly for up to 12 hours after medication. The efficacy variables analyzed were the sum of pain-intensity differences, total pain relief, onset of analgesia, and the patient's opinion of the study drug. Time-effect curves were made from the pain-relief and pain-intensity difference scores. The analgesic potency of both 100 and 200 mg of etodolac was comparable to 650 mg of aspirin and superior to placebo. Like aspirin, both doses of etodolac showed significant analgesia within one hour and a significantly longer duration of action than placebo.
