Viagra serves to be the anti impotence drug introduced by Pfizer and contains the active ingredient called sildenafile citrate to treat the problem of male impotence. The ingredient helps in relaxing muscles and raising the flow of blood to certain regions of the body. Consumption of Viagra helps in increasing the capacity to get as well as sustain strong erections when sexually stimulated. Males taking Viagra have also reported increased sexual drive, stamina and fast recharge. The drug works in blend with sexual stimulation in order to achieve the highest possible level of sexual satisfaction. But it is important to note that this drug does not guarantee safety from facing sexually transmitted diseases like Hepatitis and HIV.
In other words, when a male is stimulated sexually, his brain offers a signal which produces chemicals that relax blood vessels present in his penis. These are called as “hardeners”. When the blood vessels get calm by production of these Hardeners, the flow of blood raises eventually and erect the penis. However nature has even designed the means to achieve penis erection. When the hardeners are produced in order to offer relaxation of the blood vessels, the man’s body also produces ‘softeners’, so as to cut down and balance the hardeners.
When the amount of hardeners begins to get down, the softeners gain the upper hand and thus the penis erection starts to fizzle. Here Viagra helps in blocking the production or making of softeners thereby allowing the hardeners to accumulate in the blood vessels thereby providing sustained and harder erections.
It is imperative to note that Viagra cannot take the role of sexual stimulation. Rather, it lets the chemicals produced by stimulation to do their job. After the sexual activity, when the man’s brain does not create hardeners anymore, there is natural subsiding of the erection. Also, when the effects of the drug go down, the general body processes are started again.
The drug, Viagra is easily available in tablet form and needs to be consumed orally. Generally the drug needs to be taken an hour before you indulge in sexual activity but it can be consumed anytime as and when required. It actually takes about 30 to 45 minutes to offer its effect and when the drug starts showing its results, the effect lasts for about four to five hours. In case you consume Viagra after taking a high fat meal like chips, French fries, burger etc, the drug may take some time to show its effects.
