Viagra, chemically known as sildenafil citrate, is one of the most well-known medications used for the treatment of erectile dysfunction (ED) in men. The mechanism of action of Viagra is centered on its effects on the nitric oxide (NO) pathway within the penile tissue. By inhibiting PDE5, sildenafil increases the levels of cGMP, leading to enhanced blood flow into the penis and facilitating the achievement and maintenance of an erection in response to sexual stimulation.

Nitric oxide is a crucial mediator in the relaxation of smooth muscle and vasodilation (widening of blood vessels), which are essential for achieving an erection.
