STENDRA™ mechanism of action

The physiological mechanism of penile erection involves the release of nitric oxide (NO) into the corpus cavernosum during sexual stimulation. It does not then activate the enzyme guanylate cyclase, which leads to an increase in cGMP levels, causing relaxation of the smooth muscles of the corpus cavernosum and allowing blood flow. stendra-eu.com Avanafil does not have a direct relaxing effect on the isolated human cavernous body, but enhances the action of NO by inhibiting PDE5, which is responsible for the degradation of cGMP in the cavernous body. Since sexual stimulation is necessary to trigger the local release of nitric oxide, inhibition of PDE5 has no effect in the absence of sexual stimulation.

In vitro studies have shown that avanafil is selective for PDE5. Its influence on PDE5 more powerful than other famous phosphodiesterase (more than 100 times for pde6; more than 1000 times for PDE4, PDE8 and PDE10; more than 5000 times for PDE2 and PDE7; more than 10,000 times for PDE1. , PDE3, PDE9 and PDE11). Avanafil is more than 100 times more effective against PDE5 than PDE6, which is found in the retina and is responsible for phototransduction. In addition to the smooth musculature of the human body, PDE5 also manifests itself in other tissues, including platelets, smooth muscles of vessels and internal organs, as well as skeletal muscles, brain, heart, liver, kidneys, lungs, pancreas, prostate, bladder, testicles and seminal vesicles.
