Thirty-eight patients maintained on opioid analgesics for non-malignant pain were retrospectively evaluated to determine the indications, course, safety and efficacy of this therapy. Oxycodone was used by 12 patients, methadone by 7, and levorphanol by 5; others were treated with propoxyphene, meperidine, codeine, pentazocine, or some combination of these drugs. Nineteen patients were treated for four or more years at the time of evaluation, while 6 were maintained for more than 7 years. ⋯ No toxicity was reported and management became a problem in only 2 patients, both with a history of prior drug abuse. A critical review of patient characteristics, including data from the 16 Personality Factor Questionnaire in 24 patients, the Minnesota Multiphasic Personality Inventory in 23, and detailed psychiatric evaluation in 6, failed to disclose psychological or social variables capable of explaining the success of long-term management. We conclude that opioid maintenance therapy can be a safe, salutary and more humane alternative to the options of surgery or no treatment in those patients with intractable non-malignant pain and no history of drug abuse.

Clinical Trial Controlled Clinical TrialEfficacy of low dose combination analgesics: acetaminophen/codeine, aspirin/butalbital/caffeine/codeine, and placebo in oral surgery pain.
A double-blind, randomized, single-dose study was performed to compare the efficacy and safety of two commonly prescribed combination analgesic products to placebo. The combinations were acetaminophen 300 mg/codeine 30 mg(†), and aspirin 325 mg/butalbital 50 mg/caffeine 40 mg/codeine 30 mg(††). One hundred twenty-three (123) oral surgery outpatients took study medications when their pain became moderate to severe and recorded the levels of pain intensity, pain relief, anxiety and relaxation at 30 minutes and hourly for 6 hours after dosing. ⋯ Only 11 patients reported mild, transient adverse effects; the most common was drowsiness. The adverse effects occurred equally among the three treatment groups. In this study, the aspirin/butalbital/caffeine/codeine combination was significantly superior to placebo and somewhat better than acetaminophen/codeine.

Comparative Study Clinical Trial Controlled Clinical Trial
Intravenous dezocine for postoperative pain: a double-blind, placebo-controlled comparison with morphine.
Dezocine, a new mixed agonist-antagonist opioid analgesic, and morphine were compared in a double-blind study in 206 patients with postoperative pain. The analgesic efficacy of single intravenous injections of dezocine (2.5, 5.0, and 10.0 mg), morphine (5.0 mg), and placebo was assessed by verbal and visual scales at regular intervals for six hours after administration. All active treatments provided greater pain relief than placebo. ⋯ All active treatments produced mild to moderate sedation. Side effects were few and mild or moderate with all of the treatments. The physician's and the patients' evaluations favored dezocine in a dose-dependent order, with morphine 5 mg rated lower than dezocine 5 mg and higher than dezocine 2.5 mg.
