Indications and Usage
It is indicated to achieve or sustain an erection due to erectile dysfunction. It improves the erectile response when a man is already sexually stimulated, but it does not provide sexual stimulation.
When sexual stimulation occurs, nitric oxide is released by the nervous system in the erectile tissue of the penis. Nitric oxide stimulates an enzyme that produces messenger cyclic guanosine monophosphate (cGMP).
cGMP causes the arteries in the penis to dilate, so that the arteries and the erectile tissue fill with blood and eventually an erection occurs.
