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 700 mg Drug: Carisoprodol SR 500 mg Drug: Placebo Phase 3

Detailed Description:


This will be 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 consists of a baseline screening (Study Day 1), during which subjects will be evaluated for inclusion/exclusion criteria, and a 7-day double-blind treatment period (Study Day 1 through Study Day 7). Subjects will be randomly assigned to be dosed twice daily with one of the following double-blind treatments: SR carisoprodol 500-mg tablets, SR carisoprodol 700-mg tablets, or placebo.

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

A pharmacokinetic (PK) substudy will be conducted at selected sites. These sites will obtain 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 Rated Change Relief From Starting Backache of Pain on a 100-point Visual Analog Scale [ Time Frame: baseline to 14 days ]
    on a visual analog scale of 0 to 100 millimeters(mm) with 0 being no pain and 100 being maximum pain By measuring the amount of pain before and during treatment done at each visit and recording the difference in mm.During treatment scores were averaged and this average was compared to the baseline value.

Secondary Outcome Measures :
  1. Subject Functional Assessment Based on the Roland-Morris Disability Questionnaire (RMDQ) [ Time Frame: baseline and day +14 ]
    Subject functional assessment based on the Roland-Morris Disability Questionnaire (RMDQ)at day 14.Subjects were asked to read a list of 24 sentences that people have used to describe themselves when they had back pain, and were asked to mark those statements that described their condition that day. The number of marked statements was added. A decrease in the number of marked statements from baseline represented improvement on the RMDQ.
