What is Viagra?

The little blue pill has become one of the most known medications all over the world and even made its way into popular culture. Viagra is still in the headlines and topics of discussion well after a decade since its introduction to the market. In 1998 it has made a worldwide stir with its appearance and until now it remains to be widely discussed both by men and women. Not to mention that it remains to be the most sold drug for male impotence – a market, which Viagra has literally created with its appearance. But do you know what Viagra is and how it helps treat erectile dysfunction? If you don't, you should definitely read this!

Viagra makes part of the drug class known as PDE-5 inhibitors. Viagra was the first among these medications, and its pain competitors – Cialis and Levitra – are also from this medication class. The mechanism of action in PDE-5 inhibitors involves blockage of a specific enzyme, which is responsible for the functioning of the long muscle at the base of the penile shaft. This muscle regulates the blood circulation in the penis, and when it's relaxed more blood flows into the penile shaft, filling the cavernous bodies and forming a hard and durable erection. Thus, if put simple, Viagra works by stimulating the blood flow into the penis and helping achieve better erection even if there are problems with this.

Viagra is primarily used when erectile dysfunction has physiological causes that affect the blood circulation. It is very likely to be prescribed with conditions such as diabetes, high blood pressure, post-cancer treatment, injury to the penis or pelvis, high cholesterol, and a set of others. However, make sure to consult with your doctor before using Viagra, since only a healthcare professional can prescribe you with the right dosage of Viagra.
