Filter by:The purpose of this study is to evaluate the safety and effectiveness of the drugs yohimbine and naltrexone in treating men with erectile dysfunction (ED) (the inability to achieve or maintain penile erection for satisfactory sexual performance). ED is a medical and psychological problem that is usually associated with increased age. Evidence suggests that specific neurotransmitter systems are involved in the regulation of sexual function. Yohimbine and naltrexone are drugs that may influence these neurotransmitter systems. This study will use different doses of yohimbine and fixed doses of naltrexone to determine their effectiveness in treating ED. Participants in this study will be screened with a medical history, physical examination, blood and urine tests, and an electrocardiogram (ECG). The study will consist of three outpatient visists.
