The generic name of the orally-ingested drug Viagra is Sildenafil Citrate, which operates by helping in the release of the chemical nitric oxide inside the corpus cavernosum within the male penis. An increase in the amount of the chemical cyclic guanosine monophospate is the result of the inhibited binding of the receptors to the enzyme called guanylate cyclase, and with the consequence of a smooth relaxation of the muscle within the corpus cavernosum, increasing the circulation of blood and the penis, and enhancing an erection.
