Official title
This Protocol is a Randomized Prospective Study Comparing Prophylactic and on Demand Sildenafil Citrate Usage Administered During and After Radiotherapy With or Without Hormone Therapy Versus Radiotherapy With or Without Hormone Therapy Alone for the Preservation of Erectile Function After Therapy for Potent Patients With Clinically Localized Prostate Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Radiation sometimes affects the ability for a person to have a normal erection. Complete loss of erections after radiation treatment can happen in 40-50% of treated patients. There are medications, like sildenafil (also known as Viagra), that can help the ability to get back erections in almost 70% of such patients. The purpose of this study is to see if taking Viagra every day starting right before, during and for about 6 months after treatment, could reduce the risk of long-term erectile dysfunction.
