Input: This updated review includes 20 studies, with 2641 participants. For oxycodone 15 mg alone compared with placebo, the NNT for at least 50% pain relief was 4.6 (95% Confidence Interval 2.9 to 11). For oxycodone 10 mg plus paracetamol 650 mg, the NNT was 2.7 (2.4 to 3.1). A dose response was demonstrated for this outcome with combination therapy. Duration of effect was 10 hours with oxycodone 10 mg plus paracetamol 650 mg, and 4 hours with half that dose. Fewer participants needed rescue medication over 6 hours at the higher dose. Adverse events occurred more frequently with combination therapy than placebo, but were generally described as mild to moderate in severity and rarely led to withdrawal. Single dose oxycodone is an effective analgesic in acute postoperative pain at doses over 5 mg; oxycodone is two to three times stronger than codeine. Efficacy increases when combined with paracetamol. Oxycodone 10 mg plus paracetamol 650 mg provides good analgesia to half of those treated, comparable to commonly used non-steroidal anti-inflammatory drugs, with the benefit of longer duration of action.
Output:

This review update assessed evidence from 2641 participants in 20 randomised, double blind, placebo-controlled clinical trials of oxycodone, with or without paracetamol, in adults with moderate to severe acute postoperative pain. Oral oxycodone 10 mg plus paracetamol 650 mg provided effective analgesia. About half of those treated experienced at least half pain relief over 4 to 6 hours, and the effects lasting up to 10 hours. Higher doses gave more effect. Associated adverse events (predominantly nausea, vomiting, dizziness and somnolence) were more frequent with oxycodone or oxycodone plus paracetamol than with placebo, but studies of this type are of limited use for studying adverse effects. Limited information about oxycodone on its own suggests that it provided analgesia at doses greater than 5 mg, and that addition of paracetamol made it more effective.
