Clinical Trial Controlled Clinical Trial
An evaluation of the analgesic efficacy of three opioid-analgesic combinations in postoperative oral surgery pain.
The analgesic efficacy of a hydrocodone-acetaminophen combination, a codeine-acetaminophen combination, a codeine-APC (aspirin, phenacetin, and caffeine) combination, and a placebo was evaluated in outpatients who had moderate or severe pain after the surgical removal of impacted third molars. Each of the active medications had a significant effect on essentially all measures of total and peak analgesia; they did not differ significantly on any measure of analgesia. Adverse effects were transitory and, in general, appear to have been related to the centrally acting component of each combination analgesic.

Randomized Controlled Trial Clinical TrialPharmacokinetics of parenteral paracetamol and its analgesic effects in post-operative dental pain.
A double-blind, randomised, crossover trial was undertaken to compare the analgesic effects of a single dose of paracetamol (1000 mg i.v.) with placebo in the immediate post-operative period following removal of impacted lower third molars. There was no significant difference in the pain relief between paracetamol and placebo in the first hour following injection. ⋯ Plasma concentrations of paracetamol were measured and pharmacokinetic variables were determined. Over the four hour period of investigation there was no clear relationship between analgesia and paracetamol concentration in either central or peripheral compartments.

Age and morphine analgesia in cancer patients with postoperative pain.
Our objective was to identify age-related differences in analgesia after 8 and 16 mg morphine intramuscularly. Retrospective analyses of controlled relative analgesic potency assays in 947 postoperative cancer patients revealed differences among age groups (18 to 29, 30 to 49, 50 to 69, and 70 to 89 yr) in total pain relief and duration of relief with little differences in peak relief. Weight and initial pain intensity were in the same range among age and dose groups. ⋯ The difference in total relief between the extremes of adult age was approximately twice that with twice the dose. While in 50% of the oldest group relief was no longer obtained at 5 hr, in 50% of the youngest group relief was no longer obtained at 3 hr. These observations suggest that age is a factor in morphine analgesia.
