A Study to Evaluate Two Formulations of Carisoprodol in Subjects With Musculoskeletal Spasm of the Lower Back

Lower Back Pain Clinical Trial

Official title:
Randomized, Double-Blind, Double-Dummy Trial of Two Sustained Release Formulations of Carisoprodol Compared to Placebo in Subjects With Acute, Painful, Musculoskeletal Spasm of the Lower Back

Clinical Trial Summary

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

Clinical Trial Description

Methodology:

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. ;
