PURPOSE: We evaluated the efficacy and safety of yohimbine and isoxsuprine or pentoxifylline in the management of vasculogenic erectile dysfunction. MATERIALS AND METHODS: A total of 20 patients diagnosed with arterial insufficiency and cavernous venous leakage by pharmacological penile duplex scanning underwent nonhormonal oral therapy. A randomized crossover study was performed using 5.4 mg. yohimbine plus 10 mg. isoxsuprine or 400 mg. pentoxifylline 3 times daily. Response to therapy was assessed by a sexual questionnaire and repeat penile duplex ultrasonography. RESULTS: No patient in either phase of the study in either group had a complete response to the oral regimen(s) and there was no improvement in the pre-injection or post-injection cavernous arterial peak systolic flow velocities or resistance indexes. CONCLUSIONS: Our study suggests that these oral agents, although well tolerated, were not effective in the management of these patients with mixed vasculogenic erectile dysfunction.
