Let us find out how this medication works to treat erectile dysfunction.
Viagra is a brand name for Sildenafil, a generic drug. It mainly functions as an agent that dilates the blood vessels for increasing the blood flow to different parts of the body.
Erectile dysfunction (or Impotence) causes reduced blood flow the penile nerve. This is mainly due to the presence of an enzyme called PDE5 (phosphodiesterase type5) which deters the function of cGMP (cyclic guanosine monophosphate) molecules.
In the presence of sexual stimulation, nitric oxide is released. The GTP (guanosine triphosphate) gets converted to cGMP and signals are received from the endothelial cells. In this process, Viagra inhibits the PDE5 enzyme from degrading cGMP, facilitating the release of cGMP into the blood. This relaxes the muscles around the blood vessels and causes them to expand. The blood can easily flow into the corpus cavernosum- the erectile tissue in the penis. This is how an erection can be obtained with the help of Viagra.
It is to be noted that, Sildenafil does not induce any sexual stimulation. It also does not protect one from sexually transmitted diseases (STDs).
