Erection Pills: Viagra

Particularly older men are at risk of having erection problems stemming from lack of blood flowing to the penis. In 1998 a drug was introduced to help relieve this problem, it has become the most used form of treatment, and is known as Viagra. Sold by Pfizer, it has become a huge success for the company. In this post you will get general information about the drug. It is emphasized that if you decide to move further, it is strongly advised to consult your doctor.

The active drug sold as Viagra by Pfizer is called Sildenafil citrate. The drug was originally developed for treating high blood pressure, while it was not successful for this purpose, the pharmaceutical chemists conducting the clinical trials discovered that it was effective in inducing penile erections.

Viagra, or rather Sildenafil, acts by inhibiting enzymes that regulate the blood flow in the penis. Very simply put, the drug causes the muscles of the arteries to relax, which will increase the inflow of blood, thereby making it easier to obtain an erection. The process is initiated by sexual stimulation, which means that Viagra should not cause a permanent erection.

As with any drug, using Viagra is associated with a risk of adverse side effects. The most common of which are headache, impaired vision, flushing, dyspepsia and nasal congestion. More serious, but very rare, adverse effects are heart attacks, strokes and sudden loss of hearing.

There are certain conditions which will aggravate the risks of using Viagra, in medicine, this is known as contraindications. In this case, they include taking nitric oxide donors, organic nitrites and nitrates, severe decreased liver function, severe impairment of renal function, low blood pressure, recent stroke or heart attack, and hereditary degenerative retinal disorders. Because of the risk of adverse effects and a number contraindications, I will again emphasize that before using Viagra it is strongly advised to consult your doctor. This is not as harmless a drug as some will make it seem.

In the vast majority of western countries Viagra is sold as prescription only. In some countries in South America, for example Venezuela, Viagra is sold over the counter. Some online pharmacies sell Viagra after a simple online consultation. In some countries, particularly India, companies sell generic Viagra online. These can be very dangerous and the consumer can not be sure what product he is receiving, thus health authorities strongly warn against them. They are, obviously, also illegal to import.

The emergence of erection pills has meant improved life quality for thousands of men and couples, it marked a great improvement in the treatment of a serious condition. But these are still drugs and should be treated with respect and care. Before you decide to use them, make sure that your problems doesn't stem form elsewhere, and make sure it is medically advisably.
