Purpose: We compare the systemic effects, local tolerance and effectiveness
of topical gel formulations on the penis containing alprostadil (prostagla
ndin E1) plus 5% SEPA versus SEPA alone (placebo) in men with erectile dysf
unction.
Materials and Methods: Erectile response, skin discomfort and erythema were
measured in 48 men with erectile dysfunction secondary to vascular, neurog
enic, psychogenic or mixed etiologies in this single-blind, placebo control
led trial.
Results: Application of prostaglandin E1 gel correlated positively with ere
ctile response as 67 to 75% of patients had an erection compared to 17% of
controls (p <0.001). Blood pressure and heart rate varied minimally. No ser
ious adverse effects were observed in the 48 patients, although the majorit
y had skin discomfort.
Conclusions: Topical prostaglandin E1 gel applied to the penis appears to b
e safe, and facilitates audiovisual and tactile stimulation resulting in an
erection when given in a clinic setting. Consequences to the female partne
r remain unknown.
