Randomized Controlled Trial Clinical TrialDose-related effects of oral acetaminophen on cold-induced pain: a double-blind, randomized, placebo-controlled trial.
The cold-pressor test is a widely used pain-induction model in humans. This method has been shown to be a sensitive measure for detecting opioid analgesia. However, nonsteroidal anti-inflammatory drugs have not produced consistent analgesic effects with use of this model. ⋯ There were statistically significant main effects of both dose and time (pain and bothersomeness ratings decreased with increasing drug dose and increased over time). In pairwise comparisons only the contrast between the highest dose of acetaminophen (1000 mg) and placebo reached statistical significance. Results from our study suggest that the cold-pressor method may have clinical value in evaluating nonopioid analgesic agents.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of propacetamol and morphine in postoperative analgesia].
To compare the analgesic efficacy and tolerance of propacetamol and morphine, 80 patients in good clinical condition were included in a prospective, parallel, randomized double blind trial after elective surgery expected to elicit light to moderate postoperative pain. At the end of general anesthesia, 40 patients received 30 mg/kg propacetamol and 40 0.2 mg/kg morphine, as a 15-min intravenous infusion. The groups were similar for age, weight and duration of anesthesia. ⋯ No significant differences were observed in blood oxygen saturation, blood pressure, heart rate, body temperature and vigilance evaluated by the trailmaking test. Nausea was present in 4 cases under propacetamol and 3 under morphine, and pruritus in 2 and 7 cases, respectively. In conclusion, propacetamol may represent an alternative to morphine for pain prevention after mildly to moderately painful surgery in situations where the use of opioids is unsuitable.

Randomized Controlled Trial Clinical TrialEfficacy and safety of acetaminophen, aspirin, and caffeine in alleviating migraine headache pain: three double-blind, randomized, placebo-controlled trials.
To assess the effectiveness of the nonprescription combination of acetaminophen, aspirin, and caffeine in alleviating migraine headache pain. ⋯ The nonprescription combination of acetaminophen, aspirin, and caffeine was highly effective for the treatment of migraine headache pain as well as for alleviating the nausea, photophobia, phonophobia, and functional disability associated with migraine attacks. This drug combination also has an excellent safety profile and is well tolerated.
