6.2 Do oral meds work?
Viagra has reported success rates between 65-88% overall, as opposed
to 39% for placebo. Pfizer reports that patients who kept sexual
activity diaries in their studies reported an average of 2.0
attempts/week at intercourse, and 1.3 successes/week (as opposed to
0.3 successes/week for placebo). However, the American Urology
Association has expressed concerns that it may not work as well in men
whose Erectile Dysfunction has organic causes.
In the package insert, Pfizer gives these figures from their studies:
Cause % Successful attempts % reporting erection
(from diary) improvement overall
Diabetes 48 57
Spinal-cord
injury 59 83
Radical
prostatectomy NA 43
Overall 84 70
Success rates of about 40% have been reported for Vasomax, and
apomorphine has been successful in about 70% of cases. Yohimbine works
in 15-20% of patients. Unlike the other drugs, which are taken around
30 minutes before an erection is desired, yohimbine must be taken
three times daily and Erectile Dysfunction can return when it is stopped.
