STENDRA™ and alcohol
Patients should be aware that alcohol and PDE5 inhibitors, including STENDRA™ , act as mild vasodilators. When light vasodilators are taken in combination, the blood pressure lowering effects of each compound can be amplified. Therefore, physicians should inform patients that excessive alcohol consumption (for example, more than 3 units) in combination with STENDRA™ may increase the risk of orthostatic signs and symptoms, including increased pulse, decreased standing blood pressure, dizziness and headaches.

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.
Effect of STENDRA™ on erectile response
In a single-dose, placebo-controlled, blind study of 82 patients with organic and / or psychogenic erectile dysfunction, visual sexual stimulation resulted in an improvement in erection after administration of STENDRA™ compared to placebo, evaluated by an objective measure of hardness and duration. erections (RigiScan ® ). Efficacy was evaluated with RigiScan at discrete time intervals ranging from 20 to 40 minutes post-administration and 100 to 120 minutes post-administration.
Effect of STENDRA™ on blood pressure
Single oral doses of STENDRA™ (200 mg) administered to healthy male volunteers resulted in mean changes in systolic / diastolic blood pressure from baseline of -5.3 / -3.7 mm HG.1 hour after administration, compared with mean baseline changes in the placebo group. 2.7 / -0.4 mm HG the reduction in systolic / diastolic blood pressure 1 hour after taking STENDRA™ 200 mg compared to placebo was 8.0 / 3.3 mm HG.
