Treatment of Erectile Dysfunction

Male erectile dysfunction is frequent in patients with autonomic failure. Sildenafil (Viagra®) is useful in treating male erectile dysfunction. The effect of this drug on blood pressure in patients with autonomic failure is not fully known. This clinical trial will determine whether Sildenafil affects blood pressure in patients with primary autonomic failure. Patients in the trial will be admitted to the Clinical Research Center at The Mount Sinai Hospital for 48 hours. This study is supported in part by the NIH and by Pfizer.
