title: Tramadol/acetaminophen tablets in the treatment of postsurgical orthopedic pain.
abstract: Tramadol/acetaminophen (APAP) combination tablets were shown effective and safe for postsurgical orthopedic pain in a 6-day, multicenter, randomized, double-blind, active- and placebo-controlled study. Of 305 intent-to-treat (ITT) postsurgical patients, 153 patients undergoing arthroscopy who had at least moderate pain were randomized to receive either tramadol 37.5 mg/APAP 325 mg (mean, 4.3 tablets), or codeine 30 mg/APAP 300 mg (mean, 4.6 tablets), or placebo. Tramadol/APAP was superior to placebo for the following outcome variables: total pain relief (TOTPAR, P = .013), sum of pain intensity differences (SPID, P = .049), sum of total pain relief and sum of pain intensity differences (SPRID, P = .018), and average daily pain relief (P = .031). Similar incidence of adverse events for tramadol/APAP and codeine/APAP was found, except for constipation (0% vs 10.9%) and vomiting (8.2% vs 16.4%).
