What this trial studies

This study evaluates the effectiveness of baclofen vaginal suppositories in alleviating symptoms of Chronic Pelvic Pain (CPP). Women aged 18-65 diagnosed with CPP will be randomly assigned to receive either baclofen or a placebo for 8 weeks. Participants will complete questionnaires to assess pain and quality of life at baseline, 4 weeks, 8 weeks, and 12 weeks. The study aims to determine if baclofen can significantly improve patient-reported outcomes related to pain and overall health.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-65 diagnosed with Chronic Pelvic Pain.

Not a fit: Patients who are currently pregnant, breastfeeding, or have a history of allergic reactions to baclofen or its components may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide significant relief for women suffering from chronic pelvic pain.

How similar studies have performed: While the use of baclofen for pelvic pain is not widely tested, similar approaches in managing muscle dysfunction have shown promise in other studies.
