Patients had a documented clinical diagnosis of erectile dysfunction, a sexual partner for the duration of the study, and have a HbAlc of less than or equal to 10 at screening. Type 2 diabetic patients currently on insulin or on combination therapy with an oral hypoglycemic agent were not excluded.
Excluded were subjects who had taken more than 6 doses of any PDE5 inhibitor and/or had
taken their last dose less than 4 weeks prior to the screening visit; subjects with resting
sitting and/or standing hypotension (BP < 90/50mmHg) or hypertension (BP > 170/110mmHg);
and subjects with significant cardiovascular disease, including cardiac failure, myocardial
