Randomized Controlled Trial Clinical TrialBuprenorphine in a transdermal therapeutic system--a new option.
Advanced patch technology has yielded a novel transdermal therapeutic system (TDS) for the rate-controlled systemic delivery of buprenorphine. Buprenorphine TDS is available in three strengths with release rates of 35, 52.5 and 70 microg/h over 72 h, corresponding to daily doses of 0.8, 1.2 and 1.6 mg, respectively. In total, 445 patients with chronic pain of malignant or non-malignant origin requiring long-term treatment with potent opioid analgesics were enrolled in the clinical trial programme. ⋯ Typical opioid-related adverse events were reported with a low incidence and mild intensity. In an open follow-up study 239 patients elected to continue treatment with buprenorphine TDS. The confirmation of clinical benefit, coupled with a high level of patient compliance and improved quality of life, substantiate the usefulness of buprenorphine TDS in a practical setting.

Randomized Controlled Trial Comparative Study Clinical TrialComparative tolerability of paracetamol, aspirin and ibuprofen for short-term analgesia in patients with musculoskeletal conditions: results in 4291 patients.
The aim of this blinded, randomised, multicentre study was to compare the tolerability of aspirin, paracetamol and ibuprofen in common pain resulting from musculoskeletal conditions (MSC) in general practice with patients with other non-MSC pain conditions. Patients took aspirin, paracetamol (both up to 3g daily) or ibuprofen (up to 1.2g daily) for up to 7 days. The main outcome was the rate of significant adverse events (SGAE). ⋯ The non-MSC group showed similar intertreatment differences, but experienced fewer SGAE. No serious digestive events were observed with any of the three treatments in either group. These results show that in patients with mild to moderate pain resulting from MSC, ibuprofen given in OTC doses for 6 days is as well tolerated as paracetamol and better tolerated than aspirin.
