Vasodilator refers
to any medication that dilates an artery by relaxing
the smooth muscle in the arterial wall. Vasodilators
can also be taken after prostate cancer treatment as
a suppository, injection, or pill that is used for the
purposes of achieving erections satisfactory for sexual
intercourse. Vasodilators relax the smooth muscles in
the penis and allow blood to flow in more easily. After
prostate cancer treatments, vasodilators are a common
treatment for impotence. Often, treatment will divert
the flow of blood by sealing off veins. Vasodilators
also work only for those who are unable to achieve erections
due to the lack of the flow of blood. Some men are anxious
about re-engaging in sexual activities, and this anxiety
may actually be a self-fulfilling prophecy cause sexual
impotence. Vasodilators also work only if the penis
is physically stimulated. Vasodilators will not cause
spontaneous erections without arousal.
