Comparative Study Clinical Trial Controlled Clinical TrialA double-blind comparison of dezocine and morphine in patients with acute renal and ureteral colic.
The safety and analgesic efficacy of dezocine and morphine in the treatment of acute renal or ureteral colic due to calculi were evaluated in 2 multicenter, double-blind studies, comparing 10 mg. dezocine and 10 mg. morphine in 88 patients, and 15 mg. dezocine and 10 mg. morphine in 61 patients. All patients received an intramuscular injection of the test drug, and pain intensity and pain relief were evaluated through 4 hours after drug administration. Vital signs, degree of sedation and adverse effects also were recorded. ⋯ More morphine-treated than dezocine-treated patients withdrew from each study because of inadequate pain relief. The frequency of adverse effects was not significantly different between groups in either study and none of the patients had clinically significant changes in vital signs. These results indicate that dezocine is a safe and effective analgesic for the treatment of renal and ureteral colic due to calculi, and 15 mg. dezocine were more effective than 10 mg. morphine in this pain model.

Since the use of narcotics was initially advocated 28 years ago, serious adverse reactions, including fatalities, have been reported. At least four factors appear to contribute to these reactions: multiple drug administration, excessive dosage, inadequate monitoring, and ineffectual emergency care. Because of the relatively high incidence of life-threatening reactions and the complexity of the required emergency care, the routine use of pediatric sedation techniques that require large doses of narcotics cannot be advocated for use in the private office.
