Just what is it about viagra that makes it so popular and entices men to really go out and buy viagra from just about anywhere. I did my own research as I was really getting curious as I knew it was for impotency and erectile dysfunction but I never really understood how one little blue colored, diamond shaped pill can do bring about so much in the battle versus erectile dysfunction. As I was scanning through articles and websites, I finally saw the scientific reason why and I was amazed. As explained, sildenafil citrate, the generic compound found in each and every tablet of Viagra, is a very potent compound that can act directly in the smooth muscles controlling the penis. It inhibits a certain enzyme, (a name too long to mention in this and hard to read anyway) which is responsible for controlling the flow of blood to the penis. By inhibiting it, it allows increased blood flow to the area and doing such will help impotent men gain better erection and with the added bonus that sildenafil happens to last for around 4 hours in the body,and until such time, men who took the drug can maintain the erection. Just understanding that explanation made me a big believer of the drug and now that I do believe, I think I can attest to the effectivity of Viagra as the primary drug of choice in the therapy and management of this condition known as erectile dysfunction.
