Erectile response to vardenafil in men with a history of nonresponse to sildenafil: A time-from-dosing descriptive analysis

This descriptive analysis suggests that erection sufficient for penetration and intercourse completion was achieved within 0.25 hour and lasted for >6 hours after dosing with vardenafil 10 mg in these men with mostly moderate to severe ED and a history of nonresponse to sildenafil and who chose to make attempts during those intervals. The drug was generally well tolerated.
