Viagra (Sildenafil) is used for treating problems with obtaining or maintaining an erection. It is known as impotence, which can be a total inability to achieve an erection or keep an erection that is firm enough for sexual intercourse. Sildenafil is a selective inhibitor of cGMP-specific phosphodiesterase (PDE-5). It works by blocking PDE5, an enzyme that promotes breakdown of cGMP, which regulates blood flow in the penis. More blood in the penis means improved erection. The most popular dosage is 100 mg. Other prescription medications for the erectile dysfunction treatment are:
Cialis,
Levitra.
In a study (
Use of Sildenafil (Viagra) in Patients With Cardiovascular Disease - 1999), MD Cheitlin, AM Hutter Jr, RG Brindis, P Ganz, S Kaul, found that "sildenafil has been a valuable contribution to the treatment of erectile dysfunction, which is a relatively common occurrence in patients with cardiovascular disease."
