PDE5 is an enzyme that accepts cGMP and breaks it down. Sildenafil gums up the PDE5 and disables it, allowing an erection to occur and last longer. Viagra contains sildenafil. When a man takes Viagra, the sildenafil flows through his body and primarily affects the PDE5 enzyme in the penis. Viagra stays in the bloodstream for about 4 hours, after which it is flushed from the body via the liver and kidneys. The Viagra Process
First a man takes Viagra. The sildenafil enters his bloodstream and flows throughout his body. The sildenafil attaches to the PDE5 enzyme and disables it. When the man becomes sexually aroused, the brain tells the NANC cells in his penis to produce nitric oxide. The nitric oxide creates cGMP and the cGMP begins to relax the penile arteries.
Generic Viagra is the term given to any drug that is composed of sildenafil citrate and can be used as a substitute for the patented drug produced by Pfizer. Sometimes, one can find good deals to buy cheap generic Viagra rather than the branded drug. The average price of the branded Viagra drug is around at least seven to eight US dollars per tablet of 100mg. On the other hand, cheap generic Viagra can be available for much less than this price. Some cheap Generic Viagra substitutes are Apcalis, Aurogra, Kamagra, Scifil and Scilla. All these drugs also contain sildenafil citrate or other substitutes but give the same effect as Viagra. Sometimes cheap generic Viagra can be purchased for as little as one to two US dollars per tablet of 100mg. This is an amazing reduction over the price of branded Viagra.
