Viagra Is the Most Effective Treatment of Impotence

Viagra is the drug belonging to the category of the phosphodiesterase 5 inhibitors. The mechanism of the male reproductive organ is based on 2 enzymes, cyclic guanoyl monophosphatase (cGMP) and phosphodiestarase 5 (PDE-5). Enzyme cGMP helps to promote the blood supply to the reproductive organ of men after the stimulation. This causes the stiffness of male reproductive organ. Enzyme PDE-5 cuts off the blood supply once man attains the orgasm. Impotence is noted when the amount of enzyme PDE-5 is increased.
Viagra works as an inhibitor of the enzyme PDE-5. It also promotes the activity of the enzyme cGMP. This in combination increases the blood supply, which helps men to combat impotence. Long lasting stiff state of male reproductive organ is possible by intake of this drug as it stops the blood supply out of the male reproductive system. It contains Sildenafil citrate that works efficiently to prevent the impotence problem from occurring. It deposits the nitric oxide in the penile region, which loosens up the muscles in the penile region, this relaxes the arteries and veins, and as a result blood supply is improved. Thus, this drug helps impotent men to enjoy love-making to its fullest.
