Wheeler, PhD, Meda Pharmaceuticals, Somerset, New Jersey, on February 3. Dr. Wheeler and colleagues analysed the results from 2 randomised, controlled, multicentre trials that took place from August 2005 to June 2006. The studies evaluated 1,080 patients (aged 18-65 y) with moderate to severe investigator-rated muscle spasm and patient-reported backache. Patients were randomised to carisoprodol 250 mg (n = 533) or placebo (n = 547) 4 times daily for 7 days. Functional status was assessed at baseline and at day 3 using the Roland-Morris Disability Questionnaire (RMDQ). The mean baseline RMDQ scores were similar in both groups: 10.9 in the carisoprodol-treated group and 10.7 in the placebo group. The primary endpoint was a >=30% improvement in RMDQ by day 3 of treatment. On day 3, the carisoprodol group had achieved a clinically meaningful improvement in RMDQ: 31%, with a mean change of 3.4 from baseline, compared to a 17.2% improvement, with a mean change of 1.8, in the placebo group. Patients in either treatment group reported adverse events of drowsiness, dizziness, and headache; however, no serious adverse events were reported in these studies. Meda Pharmaceuticals supported the studies from which these data were generated.
