WHAT IS VIAGRA

Erectile dysfunction (ED) or impotence as it is often called, affects men of all ages. That's why the drug Viagra has had such success in the marketplace. There was a time when treatments were few and success of treatment was rare. That was before the ED drug everyone has heard of. That was before "the little blue pill." That was before Viagra.

Sildenafil citrate also known as Viagra is a medicine used to treat erectile dysfunction and pulmonary hypertension. The U.S. Food and Drug Administration approved Viagra for erectile dysfunction, but not to prolong erections. Viagra will not help delay ejaculation.

Viagra was developed and is marketed by the pharmaceutical company Pfizer. It works by inhibiting specific phosphodiesterase type 5, an enzyme that regulates blood flow to the penis.

Since becoming available in 1998, sildenafil has been the main treatment for erectile dysfunction, its main competitors in the market are Cialis and Levitra.

To buy Viagra online has become a common thing for millions of people in the world. That is because online drugstores not only make you buy Viagra more convenient but also offer meds you need at much lower price than your local pharmacies do.

Viagra (sildenafil) belongs to a group of medicines that delay the enzymes called phosphodiesterase from working too quickly. By controlling phosphodiesterase, sildenafil helps to maintain an erection that is produced when the penis is physically stimulated. We have all heard of the popularity of Viagra. In fact, men of all ages are finding a new found sexual youth because of the little blue pill.

Viagra works by increasing blood flow to the penis. With sexual stimulation, this causes an erection. You won't get an erection by simply taking a Viagra pill. Viagra improves the ability to have erections in about 80 percent of the men who take it.

Viagra is available in doses of 25 to 100 mg. For best results, take it one hour before having sex. The drug can be effective anywhere from ten minutes to four hours after taking a dose. It works faster when you take it on an empty stomach. When the sexual experience is over, the erection goes away: Viagra doesn't help you keep an erection. Don't take more than one dose of Viagra per day because this greatly increases the risks of severely low blood pressure.
