Generic Viagra Review

Product description

Generic Viagra is a medicine to increase potency and treat chronic erectile dysfunction. The main active ingredient of the drug is Sildenafil citrate.

Therefore, a purchase of Generic Viagra 100 mg will be by 3-4 times cheaper.

Mechanism of the pharmacological action

A physiological mechanism of the erectile function is conditioned by the release of nitric oxide in the smooth muscle fibers of the cavernous bodies during the sexual stimulation. A sexual stimulation may be visual or tactile. At this moment, a signal from the brain goes through the central nervous system and nitric oxide is produced. As a result, the blood vessels are dilated in the area of the penis, and erection appears. If there is a disorder of the erectile mechanism on some of the stages, a man has erectile dysfunction.

Sildenafil citrate is a phosphodiesterase type 5 inhibitors. This enzyme regulates a production of the nitric oxide and its vasodilating characteristics.

When Sildenafil citrate is absorbed into the systemic blood flow, it temporarily blocks the work of this enzyme, and a lot of nitric oxide is synthesized in the cavernous bodies of the penis during the sexual stimulation. It leads to the dilation of the blood vessels, an improved blood circulation, and better blood filling of the cavernous bodies. When the cavernous bodies are increased, the blood outflow from the penis slows, due to which a firm and long-term erection is kept till the end of the sexual intercourse.

Main characteristics of the pharmacological properties of Sildenafil citrate

      Sildenafil citrate acts selectively to PDE5 enzyme and only in the area of small pelvic. It does not provide a general vasodilating action and does not influence on the functions of the cardiovascular system

      Sildenafil does not influence directly on the production of nitric oxide. It blocks the work of the enzymes which worsen the production of this enzyme during the sexual arousal

     Sildenafil does not influence on the level of the sexual arousal. It does not contain the male sexual hormones (testosterone and dihydrotestosterone), and therefore it is not able to cause a strong sexual arousal and does not cure of the libido disorder

Generic Viagra (Sildenafil) is not able to block PDE5 on a recurring basis. The action of the drug lasts for about 4-5 hours, and then a concentration of Sildenafil drops in the blood plasma. At the same time, a recovery of the biological and physiological characteristics of phosphodiesterase type 5 happens, and this enzyme regulates a process of the nitric oxide release again.

Sildenafil is not able to cure of the erectile dysfunction. It does not influence on a cause of the sexual pathology and is specially developed in order to give a man an opportunity to have a complete sexual intercourse even during severe forms of the erectile dysfunction.
