Viagra is the powerful stimulator of erection

All people know this name and this is not simply clever publicity trick. The preparation, developed just few decades ago, has become a real solution for men with problems of impotence. In fact, what is erectile dysfunction? It is the pathology of physiological or psychogenic (often mixed) type, which does not give a sufficient amount of blood to fill cavernous body of penis during sexual stimulation. Even after eliminating the psychological causes of the problem, the chemical reaction remains, isozyme just suppresses the substances generating during erection, preventing the blood inflow in the penis.

The solution is simple – to block the enzyme, PDE5, phosphodiesterase. But the same enzyme, only with other numeric value, is present in other tissues of the body and the medication should have a very narrow range of action in order not to provoke a heart attack or other adverse effects. So sildenafil was developed.

Its pharmacological action directed on strengthening of nitric oxide effect, which is released to cavernous body during stimulation. The nitric oxide causes increase of the level of cGMP, relaxation of smooth muscles of the penis and filling vessels with blood. When there are some disorders this process is interrupted and erection is not happened. Sildenafil blocks the action of PDE5, which fermented cGMP– this allows blood to circulate freely. It should be mentioned that Viagra is several thousand times more active against PDE-5 than, for example, to the enzyme PDE-3, which plays a key role in controlling of myocardium muscle contraction. So, at Viagra taking there is no risk that the active ingredient will negatively affect other isoenzymes involved in the vital processes. In addition, the effect of sildenafil is reversible – all functions are restored after the period of action of the drug. That is why Viagra does not cure erectile dysfunction, but is a means of symptomatic therapy.

Combination Viagra and other preparations

There are drugs that influence the absorption and action of sildenafil. The attending doctor should know about all medicines that a patient takes regularly or from time to time. For example, for men administrating nitroglycerin or other drugs containing organic nitrates and nitrites, sildenafil is strictly prohibited – this may lead even to a lethal outcome, as the combined action of both medicines cause sudden hypotensive effect. It is necessary the consultation with an urologist before starting administration of Viagra, even if the drug is OTC. Viagra is not a magic pill for erection that is suitable for everybody. This is the same drug as many others. What drugs can affect the health of the patient, if taken with sildenafil?

Secondly, the doctor should identify the causes of erectile dysfunction and to prescribe therapy, in the complex of which it is admissible to use Viagra.

In addition, the physician should evaluate the risk of blood pressure decrease while taking the drug, Viagra is undesirable at severe disorders of blood pressure regulation.
