Viagra: The love potion

In the end it turned out that the secret to combating the effects of impotency did not lie in snake venom, frog tails or the ever elusive fairy dust.  Instead it lay in some unique magical substance called Sildenafil citrate. Sildenafil is the main ingredient of Viagra.

The journey of Viagra was hardly a straight one. True, ever since the early 70s scientists had been aware of the importance of muscle relaxation in the treatment of impotency. But up until the discovery of Sildenafil Citrate, the jury was still out in search of a fitting chemical required for achieving the desired relaxant effect. And so when, in tests conducted to study its viability as a drug used for low pressure conditions, test subjects announced that one of the resultant effects was a rejuvenated sexuality, Pfizer realized the importance of the application and immediately seized on it.

With more than a billion dollars in sales since then, Viagra only goes to clearly underline how desperately the world needed an anti impotence pill.

How does Viagra work?

Viagra is grouped under a category of drugs known as phosphodiesterase inhibitors. As the name suggests, taking Viagra blocks the action of the enzyme that goes by this name. Some of the actions of the enzyme phosphodiesterase-5 (also known as pde-5) include the blocking of the production of Nitric oxide. By preventing the actions of this enzyme, Viagra allows the increased production of Nitric oxide in the body. With improved Nitric oxide levels, the body experiences improved heart functionality as well as an enhancement of the various blood vessels. It also permits the relaxation of the various body muscles, in particular those located in the penis. This relaxing of the muscles permits the easier flow of blood into the penile areas. Blood flow is of great importance because the male organ uses it for the creation of an erection in a series of hydraulic like actions.

As blood flows into the penis, it is trapped in place by the constriction of the veins responsible for the out flow of blood. The sponge like tissues which make up the bulk of the penis slowly becomes engorged with the sustained flow of blood and this result in a transition from the flaccid state to the erect state. The dosage of Viagra required for a successful erection will depend on the severity of the condition surrounding the impotency. For instance individual with badly stiffened arteries might require more than the traditional 50mg dosage.

Viagra tablets are offered in dosages of 25mg, 50mg and a 100mg.

By virtue of its operation, Viagra does not result in many side effects. Most of the reported cases of side effects -i.e. Headaches, flushing and slight aches are mostly an effect of the increased flow of blood in the body. These are quickly found to fade as the drug is slowly used by the body.

Thanks to the advancement of internet technology and banking services, it is very easy to buy drugs online. Not many people are comfortable with their impotency. Online pharmacies provide a much preferred option in anonymity than an over the counter approach does. It is also possible to buy Viagra online without prescription in most online pharmacies. Best of all, Viagra tablets are found to be more affordable with online use. They are also a lot more effective. More effective for instance, than those, annoying frog tails.
