Exploring the magic of Viagra.

When a man is said to be impotent, the man is said to be suffering from a condition that makes him incapable of having an erection when he is sexually aroused. Though impotence or erectile dysfunction, as medical practitioners refer to it, is normally viewed as normal when it occurs occasionally, it becomes a problem, however, when the inability to achieve erection for sexual satisfaction or penetration becomes frequent. Quite distinct from other sexual dysfunctions – premature ejaculation, weak libido, etc. – in that sexual penetration might be attained in these other cases, ED is a common problem whose incidence increases with age.

Statistics have shown that the incidence of ED is on the rise, and it is on record that approximately 10 to 15 million men in the United States are believed to be impotent.

A further breakdown of this figure shows that slightly less than 4 percent of males between the age bracket of 30 to 45, approximately 7 percent between the ages of 45 and 55 years, about 25 percent at 65, and about 75 percent of male from 80 years and above, are affected by ED.

Impotence is classified as either primary or secondary, depending on the time of its commencement – primary and secondary. Primary impotence occurs when the genitals are faulty. Secondary impotence occurs when a man, who used to have a normal ability to attain erection, suddenly loses his erectile ability. Secondary impotence could occur either during adolescence or adulthood.

It is generally believed that most impotent cases had physical causes, which were often aggravated by psychological factors by the time treatment is sought.
The several types of physical treatment for impotence included the injection of a drug in the corpus cavernosum of the penis of men who were impotent (intracorporeal pharmotherapy), drugs administered through the oral or topical routes, etc. However, none of these drugs produced little satisfactory results. As problems, such as scarring as a result of prolong use – in the case of the injection – and lack of adequate information on the side effects and drug interactions by doctors – in the case of the drugs administered through the oral and topical routes – made these treatment methods unpopular.

However, the advent of Viagra tablets in 1998 – the first drug to be approved by the US Food and Drug Administration as the oral treatment of choice for ED – brought about a sea change in the treatment of ED.
Such is the popularity of this drug among men who buy Viagra online that even the introduction of other drugs into the market, which work similarly to Viagra, have been overshadowed by the magic blue pills.

This popularity is in no small part helped by the fact that anyone who buys Viagra online, it has long been established, would be doing so with the knowledge that Viagra tablets are effective inhibitors of the phosphodiesterase type 5 (PDE 5) enzyme. And like other PDE 5 inhibitors, sildenafil citrate, the active ingredient in Viagra, relaxes the smooth muscles. The relaxation of the smooth muscles is facilitated when the levels of cyclic guanosine monophosphate (cGMP), which is physiologically degraded by the PDE 5, are raised. The relaxation of the smooth muscles enables blood to flow into the corpus cavernosum of the penis, and subsequently makes the penis to enlarge and become stronger.

Available on the internet, and the proliferation of internet sites offering irresistible offers now mean that this non-traditional source of distribution is now the first option for the majority of those who want to buy Viagra cheap.
Viagra is the trademark of Pfizer Inc., the largest drug maker in the world.
