Visual impairment

In rare cases, during post-approval use of all of the inhibitors of PDE5, including Buy Viagra Bitcoin, reported NESN is a rare disease and the cause of the decrease or loss of vision. Most of these patients had risk factors, such as decreased ratios of excavation diameter to optic disc (stagnant disc), age over 50, diabetes, hypertension, CHD, hyperlipidemia, and Smoking. In an observational study evaluated whether recent use of drugs class of inhibitors PDE-5 with an acute onset NESN. The results indicate approximately a 2-fold increase in risk of developing NESN within 5T1/2 after application of the PDE-5 inhibitor. According to published literature, the annual incidence of npins IS 2.5–11.8 cases per 100,000 men aged ≥50 years in the General population.

A decrease in the clearance of Buy Viagra Bitcoin with simultaneous use of inhibitors of CYP3A4 isoenzyme (ketoconazole, erythromycin, cimetidine).

Cimetidine (800 mg), a nonspecific inhibitor of CYP3A4 isoenzyme, when taken together with Buy Kamagra With Bitcoins (50 mg) causes an increase in the concentration of Kamagra Bitcoin Pharmacy Online in plasma by 56%.

A single dose of 100 mg of Buy Viagra Bitcoin together with erythromycin (500 mg/day 2 times a day for 5 days), a moderate inhibitor of CYP3A4 isoenzyme, while achieving a constant concentration of erythromycin in the blood, leads to an increase in the AUC of Buy Viagra Bitcoin by 182%.

Buy Viagra Bitcoin is a potent selective inhibitor of cGMP-specific PDE-5.



Mechanism of action

The implementation of the physiological mechanism of erection is associated with the release of nitric oxide (NO) in the cavernous body during sexual stimulation. This, in turn, leads to an increase in the level of cGMP, the subsequent relaxation of smooth muscle tissue of the cavernous body and an increase in blood flow.

Buy Viagra With Bitcoin does not have a direct relaxing effect on the isolated cavernous human body, but enhances the effect of nitric oxide by inhibiting PDE-5, which is responsible for the disintegration of cGMP.

Selective Buy Viagra Bitcoin against PDE5 in vitro, its activity against PDE5 superior activity against other known PDE isoenzymes: PDE-6 — 10 times; PDE-1 more than 80 times; PDE-2, PDE-4, PDE-7 PDE–11 more than 700 times. Buy Viagra Bitcoin is 4000 times more selective for PDE-5 than PDE-3, which is crucial because PDE-3 is one of the key enzymes in the regulation of myocardial contractility.

A prerequisite for the effectiveness of Buy Viagra Bitcoin is sexual stimulation.

Buy Viagra Bitcoin restores impaired erectile function in conditions of sexual stimulation by increasing blood flow to the cavernous bodies of the penis.
