Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialThe CONCEPT trial: a 1-year, multicenter, randomized,double-blind, double-dummy comparison of a stable dosing regimen of salmeterol/fluticasone propionate with an adjustable maintenance dosing regimen of formoterol/budesonide in adults with persistent asthma.
A patient-driven, adjustable maintenance dosing (AMD) approach to asthma therapy, in which the dose is adjusted by patients according to the severity of their symptoms, has recently been compared with fixed-dose therapy in open-label studies. ⋯ In this adult population with persistent asthma, stable dosing of SAL/FP 50/250 microg BID resulted in significantly greater increases in symptom-free days, days free of rescue medication, and morning PEE, as well as almost halving the exacerbation rate, compared with AMD of FOR/BUD 6/200 microg. The results suggest that there is a minimum daily amount of maintenance therapy necessary to prevent exacerbations in adults with persistent asthma.

Multicenter StudyEffectiveness and tolerability of the buprenorphine transdermal system in patients with moderate to severe chronic pain: a multicenter, open-label, uncontrolled, prospective, observational clinical study.
A new transdermal delivery system (TDS) for the rate-controlled systemic delivery of buprenorphine is available in 3 patch strengths, with release rates of 35, 52.5, and 70 microg/h over 72 hours, delivering daily amounts of 0.8, 1.2, and 1.6 mg, respectively. Randomized, double-blind, placebo-controlled, Phase III clinical trials in >400 patients with severe pain of malignant or nonmalignant origin have shown the analgesic efficacy of buprenorphine TDS. ⋯ In the population studied, buprenorphine TDS was effective in alleviating cancer and noncancer pain and was well tolerated overall.

Randomized Controlled Trial Multicenter Study Clinical TrialAnalgesic efficacy and tolerability of oxycodone 5 mg/ibuprofen 400 mg compared with those of oxycodone 5 mg/acetaminophen 325 mg and hydrocodone 7.5 mg/acetaminophen 500 mg in patients with moderate to severe postoperative pain: a randomized, double-blind, placebo-controlled, single-dose, parallel-group study in a dental pain model.
Combination therapy has been widely used for the clinical management of acute pain. By combining 2 drugs with different mechanisms of action, such therapy provides additive analgesic effects while reducing the risk for adverse effects. ⋯ In this study in patients with moderate to severe pain after surgery to remove impacted third molars, oxycodone 5 mg/ibuprofen 400 mg provided significantly better analgesia throughout the 6-hour study compared with the other opioid/nonopioid combinations tested, and was associated with fewer adverse events.
