Viagra as a treatment for erectile dysfunction
Erectile dysfunction is caused by a lack of blood flow to the penis when a man is sexually aroused. This can be caused by health problems, high cholesterol levels and high blood pressure are two of the main causes for erectile dysfunction. Stress and anxiety as well as more serious psychological issues such as depression can also lead to erectile dysfunction.
The lack of blood flow to the penis that results in erectile dysfunction is due to the contraction of the penile arteries and blood vessels. This contraction is caused by the enzyme phosphodiesterase type 5, known as PDE5, a vasoconstrictor which acts on the cells lining the blood vessels. The main component of a Viagra prescription is the drug sildenafil citrate which is a PDE5 inhibitor. The Viagra deactivates the PDE5 enzyme so it is unable to act on the cells of the blood vessels, resulting in an erection.
