Viagra (sildenafil) is a phosphodiesterase inhibitor (PDE-5 inhibitor) used to treat impotence (or erectile dysfunction, ED, the inability to attain or maintain a penile erection).
Erection of the penis occurs when the penis fills with blood. Filling occurs because blood vessels that bring blood to the penis increase in size and deliver more blood to the penis, and blood vessels that take blood away from the penis decrease in size and remove less blood from the penis. Sexual stimulation that leads to an erection causes the production and release of nitric oxide in the penis. Nitric oxide causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP) that is primarily responsible for increasing and decreasing the size of blood vessels carrying blood to and from the penis and causing an erection.
Viagra dosage is not based on weight, but your age can affect your dosage. Viagra comes as an oral tablet that contains the active drug sildenafil. Sildenafil is also available in generic form.
