In this posting I am going to write something about erectile dysfunction drugs which are easily available in online market.
Only three FDA approved drugs are available in the online markets which are Viagra, Levitra and Cialis. These drugs are mainly based on the principle of rectification of the vascular irregularities. Erection is mainly depends on two processes:
1) Proper flow of blood into penis.
2) Sustenance of the blood into penis during sexual activity.
This blood flow increases due to a chemical which known Nitric Oxide. But there are some enzymes which neutralize the action of Nitric Oxide. As a result penis doesn’t get proper blood flow so not erect.
Viagra and other erectile dysfunction drugs contain some chemicals which increase the flow of nitric oxide which increase the blood flow into penis that’s why penis get and sustain erection for a successful sexual intercourse.
