Official title
A Randomized, Double-Blind, Placebo-Controlled Phase II Study of Oxybutynin Versus Placebo for the Treatment of Hot Flashes in Men Receiving Androgen Deprivation Therapy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II trial compares the effect of oxybutynin versus placebo for reducing hot flashes in men receiving androgen deprivation (hormone) therapy for the treatment of prostate cancer . Androgen deprivation therapy decreases testosterone and other androgens through medications or surgical removal of the testicles. Relative to placebo, low- or high-dose oxybutynin may reduce hot flashes in men receiving androgen deprivation therapy.
