Effect of pretreatment with acetaminophen-propoxyphene for oral surgery pain.
|
| Abstract |
To determine the effect of pretreatment and multiple doses on postsurgical pain, a study of the relative analgesic efficacy of placebo, acetaminophen 650 mg, and propoxyphene napsylate 100 mg alone and in combination was conducted. Forty-five patients undergoing surgical removal of impacted third molar teeth under local anesthesia were randomly allocated to the four treatment regimens under double-blind conditions. The first oral dose was administered one hour preoperatively and the second dose when the pain became moderate or severe, following the dissipation of the local anesthesia. Pain intensity and pain relief were assessed using standard verbal descriptor scales at 30 minutes and hourly for four hours after the postoperative dose. Measures of total effect, peak effect and duration of their effect were derived from these descriptors. Acetaminophen was no better than placebo. For peak and total effects, propoxyphene alone and the propoxyphene-acetaminophen combination were substantially superior to both placebo and acetaminophen alone. Duration of analgesia was also significantly longer with both propoxyphene-containing treatments. No side effects were reported. The results suggest that pretreatment with a narcotic agonist markedly improves postoperative analgesia.
