The main component of Zenegra is Sildenafil.
Sildenafil affects the response to sexual stimulation. It acts by
enhancing smooth muscle relaxation using nitric oxide, a chemical that
is normally released in response to sexual stimulation. This smooth
muscle relaxation allows increased blood flow into certain areas of the
penis, which leads to an erection.
Sildenafil is applied for the treatment of erectile dysfunction (impotence) in men and pulmonary arterial hypertension.
Sildenafil may also be used for other purposes not listed above.
