Viagra is the brand name of a medication called sildenafil. Viagra helps relax the muscles in the walls of the blood vessels to help increase the flow of blood to parts of the body. Viagra helps treat erectile dysfunction in men for those who have difficulty achieving or sustaining an erection. Viagra helps improve a man’s erectile response when sexually stimulated, but does not provide sexual stimulation. When a man is sexually stimulated, a chemical called nitric oxide is released by the nervous system in the erectile tissue of the penis. This chemical stimulates an enzyme that created messenger cyclic guanosine monophosphate (cGMP). cGMP causes the arteries in the penis to dilate so the arteries and the erectile tissue fill up with blood, creating an erection. Viagra works by preventing cGMP from becoming degraded, allowing the blood to flow and an erection to continue.
