Viagra is the most potent of all drugs in treating sexual impotence. The medication works in the body by enhancing the blood flow to the penile region. This enables men to experience sustained erection for a considerable period of time. But, erection can happen only at instances of proper sexual stimulation.

Medical experts argue the potential of the medication to treat pulmonary arterial hypertension too. Although an effective medication for men, it is not suitable for use in women. Sildenafil (Viagra) works by restraining the growth of enzyme PDE5. This in turn destabilizes an enzyme by name cGMP. In fact, this cGMP enzyme is what that regulates the blood flow to the penile region. Once the flow of blood towards the penis becomes smooth, erection gets triggered.
