Among men undergoing radiation therapy for prostate cancer, daily use of the erectile dysfunction drug tadalafil did not prevent loss of erectile function when compared with placebo, according to a study.
Erectile dysfunction is a common condition resulting from many causes, including prostate cancer treatment, according to background information in the study, which was published in the April 2 issue of the Journal of the American Medical Association. An estimated 40% of men report erectile dysfunction after radiation therapy, and half of all men use erectile aids following this therapy. Tadalafil is used to treat erectile dysfunction after prostate cancer treatment, but its role as a preventive agent has not been determined.
