AbstractA double-blind, parallel study was conducted to evaluate the analgesic effect and safety of a single 25 mg oral dose of picenadol, a centrally acting analgesic, and to compare it with a 60 mg dose of codeine and a placebo in patients with postoperative pain. Two sites using similar protocols enrolled a total of 178 inpatients with postoperative pain. Pain intensity, relief, and adverse experiences were then measured for up to 6 hours after administration of the test medications. Both picenadol and codeine were significantly more effective than placebo in reducing pain intensity (mean sum of pain intensity difference scores: picenadol 5.21, codeine 5.19, and placebo 2.82) and increasing total relief (mean total pain relief: picenadol 10.21, codeine 11.07, and placebo 6.96). Adverse experience profiles were similar among the three treatment groups.
