Brief Summary:
The purpose of this study is to determine if two sustained released formulations of carisoprodol are more effective than placebo.

Condition or disease Intervention/treatment Phase
Lower Back Pain Drug: Carisoprodol SR Drug: Placebo Phase 3

Detailed Description:


This was a randomized, double-blind, double-dummy, placebo-controlled, parallel-group study in subjects 18-70 years of age with acute, painful, muscle spasm of the lower back. The study consisted of a baseline screening (Study Day 1), during which subjects were evaluated for inclusion/exclusion criteria, and a 7-day double-blind treatment period (Study Day 1 through Study Day 7). Subjects were randomly assigned to be dosed twice daily with one of the following double-blind treatments: sustained release(SR) carisoprodol 500-mg tablets,sustained release (SR) carisoprodol 700-mg tablets, or placebo.

Subjects were evaluated in the clinic on Study Days 1, 3 and 7. Subjects who remained symptomatic on Study Day 7 were allowed to continue in the study for a 7-day, double-blind extension period at the discretion of the Investigator. Subjects were contacted by telephone for a safety follow-up 7 days after the last dose of study medication.

A pharmacokinetic (PK) substudy was conducted at selected sites. These sites obtained blood samples for PK analysis at the end of the 7-day treatment period and the 14-day treatment period, if applicable.

Primary Outcome Measures :
  1. Subject Rating of Pain on a 100-point Visual Analog Scale (VAS) [ Time Frame: up to 14 days ]
    the scale used was from 0 to 100 mm. 0 equaled no pain and 100 equaled maximum pain.participants measure their pain before treatment and during treatment at each visit

Secondary Outcome Measures :
  1. Subject Functional Assessment Based on the Roland-Morris Disability Questionnaire (RMDQ) [ Time Frame: up to 14 days ]
  2. Adverse Event Assessment [ Time Frame: up to 21 days ]
    the number of adverse events reported during the course of the study as reported by the participants
