How Generic Viagra treat Erectile dysfunction or Impotence

Generic Viagra contain Sildenafil Citrate as its most active ingredient which actually helps in getting erection. In a man suffering from Erectile Dysfunction, production of cGMP breaks down (which actually relaxes the arteries in the penis) by an enzyme called PDE-5. Because of which arteries do not sufficiently dilate and so enough blood does not reach in the penis to cause an erection.But when a man takes any of the Generic Viagra ,Sildenafil Citrate enters his bloodstream and flows throughout his body.Sildenafil Citrate of Generic Viagra attaches to the PDE-5 enzyme in his penis and disables most of it. When a man gets sexually excited, the brain sends the normal message to NANC cells in penis, producing nitric oxide (NO). The nitric oxide creates cGMP, which starts relaxing the arteries in his penis. Because the PDE-5 has already been disabled, the cGMP creation does not break down, so arteries in the penis become fully dilate. This result in more and more blood, flowing inside the penis and the penis become erect and stay erect for long enough time about four hours.
