Levitra Clinical Trials
Start
Levitra was evaluated in randomized, placebo-controlled trials involving more than 2000 men with erectile dysfunction. In two of the trials men had erectile dysfunction associated with diabetes mellitus or following radical prostatectomy for prostate cancer.
The drug’s effectiveness was assessed using a sexual function questionnaire. In addition, patients were asked to report if they were able to achieve an erection adequate for intercourse and whether the erection was maintained to allow completion of intercourse. In all of the trials, Levitra improved patients’ ability to achieve and maintain a penile erection.
