Pharmacological action

VIAGRA - a drug for the treatment of erectile dysfunction - erectile dysfunction. Acts on the natural mechanisms of erection. It is used in men suffering from erectile dysfunction of various origins (vascular, nervous erectile dysfunction).

Sildenafil is a potent and selective inhibitor of cGMP-specific type 5 phosphodiesterase (PDE5).

The physiological mechanism of penile erection involves the release of nitric oxide (NO) in the cavernous body during sexual stimulation.

Nitric oxide activates the enzyme guanylate cyclase, which leads to an increase in the level of cyclic guanosine monophosphate (cGMP), relaxation of the smooth muscles of the cavernous body and increased blood flow in the penis.

Sildenafil does not have a direct relaxing effect on an isolated human cavernous body, but actively enhances the relaxing NO effect on this tissue by inhibiting PDE5, which is responsible for the breakdown of cGMP in the cavernous body.

Sexually Aroused, local release of NO under the influence of sildenafil leads to inhibition of PDE5 and an increase in the level of cGMP in the cavernous body, resulting in relaxation of smooth muscles and increased blood flow in the cavernous body.

A prerequisite for the effectiveness of sildenafil is sexual stimulation.
