How Viagra Canada Works

Viagra Canada is an oral pill taken in the absence of possibility to achieve and maintain erection during sexual act. This condition is commonly referred to as erectile dysfunction (ED), or impotence.

Canadian Viagra appeared on the market in 1998 when it was first patented by the American company Pfizer. The medicine was developed as a drug against pulmonary heart disease, but it had a clearly manifested side effect of making it easier to achieve erection. Soon sildenafil citrate, the main component of Viagra, began to be manufactured in the shape of blue pill which we all know as Viagra in Canada these days.

The mechanism of Viagra is simpler than it may appear at the first sight. Sildenafil citrate affects the amount of phosphodiesterase type 5 in the body; to be more precise, it blocks this enzyme which is secreted when it is time to terminate the sexual act. In men with manifested ED phosphodiesterase type 5 (more commonly called PDE5) this enzyme is secreted to overproduction.

Sildenafil citrate also has vasodilatory characteristics. The pill makes the walls of the blood vessels in the body relax and absorb the optimal amount of blood, which further promotes a stable erection.

Viagra should be taken not later than one hour before it is needed. This is associated with the time needed for the onset of the action of the drug. The effect of Viagra continues for the ensuing 4 hours. During this time one may have unlimited number of sexual acts. But there is one thing to be observed, and it is the fact that Viagra is not an aphrodisiac. This means that it does not a sexual stimulator in itself; it just helps to respond with erection towards outer sexual stimulator. Viagra will not work before you are actually exposed to sexual environment and ready to engage in intimacy.

Viagra mechanisms work in the majority of patients whose impotence is conditioned by physiological reasons. But in some patients it takes several consecutive intakes for the medicine to work at its best. Sildenafil has no accumulative effect, but your body needs to adjust to the action of Viagra to respond faster and more consistently.
