Clinical data

Cardiac studies. The use of Buy Sildenafil With Bitcoin Or Credit Card in doses up to 100 mg did not lead to clinically significant ECG changes in healthy volunteers. The maximum decrease in systolic pressure in the supine position after taking Buy Sildenafil With Bitcoin Or Credit Card at a dose of 100 mg was 8.3 mm Hg.art., and diastolic pressure — 5.3 mm Hg.a More pronounced, but also transient effect on blood PRESSURE was observed in patients taking nitrates (see "Contraindications" and "Interaction").

In a study of the hemodynamic effect of Buy Female Viagra With Bitcoins in a single dose of 100 mg in 14 patients with severe coronary artery disease (more than 70% of patients had stenosis of at least one coronary artery), systolic and diastolic resting pressure decreased by 7 and 6%, respectively, and pulmonary systolic pressure decreased by 9%. Buy Sildenafil With Bitcoin Or Credit Card did not affect cardiac output and did not interfere with blood flow in stenotic coronary arteries, and also led to an increase (by about 13%) of adenosine-induced coronary flow in both stenotic and intact coronary arteries. In a double-blind placebo-controlled study of 144 patients with erectile dysfunction and stable angina, taking antianginal drugs (except nitrates), exercise was performed until the severity of symptoms of angina increased. The duration of the exercise was significantly longer (19.9 seconds; 0.9–38.9 seconds) in patients taking Buy Sildenafil With Bitcoin Or Credit Card in a single dose of 100 mg, compared with patients receiving placebo.

In a randomized double-blind placebo-controlled study, the effect of changing the dose of Cheap Viagra Professional Accept Bitcoin (up to 100 mg) in men (n=568) with erectile dysfunction and hypertension, taking more than two antihypertensive drugs, was studied. Buy Sildenafil With Bitcoin Or Credit Card improved erection in 71% of men compared to 18% in the placebo group. The frequency of adverse effects was comparable to that in other groups of patients, as well as in those taking more than three antihypertensive drugs.

Studies of visual impairment. In some patients, 1 h after taking Buy Female Viagra With Bitcoin at a dose of 100 mg with the Farnsworth-Mansell test 100 revealed a slight and transient violation of the ability to distinguish shades of color (blue/green). After 2 hours after taking the drug, these changes were absent. It is believed that color vision impairment is caused by inhibition of PDE-6, which is involved in the process of color transmission in the retina. Buy Sildenafil With Bitcoin Or Credit Card had no effect on visual acuity, contrast perception, electroretinogram, IOP or pupil diameter.
