Oxybutynin Chloride in Managing Hot Flashes

Completed · Phase 3 · Has a placebo group

Conditions studied: Breast Carcinoma, Ductal Breast Carcinoma In Situ, Hot Flashes, Lobular Breast Carcinoma In Situ, No Evidence of Disease

In brief

This randomized phase III trial studies how well oxybutynin chloride works in managing hot flashes in patients who are not candidates for, or not interested in hormone replacement therapy. Previous studies have shown that oxybutynin is effective in managing hot flashes, however doses used in prior studies have resulted in side effects. This trial is evaluating lower doses of oxybutynin with the goal of determining if they are efficacious with less side effects. ADAM-VTE
