Pharmacological action
Erinit – a venous vasodilator, has an antianginal effect. Stimulates the formation of nitric oxide in the vessel wall, which is an endothelial relaxing factor. Erinitis reduces preload (expansion of peripheral veins and a decrease in blood flow to the right atrium) and afterload (OPSS) on the heart reduces myocardial oxygen demand. It restores blood flow in small endocardial vessels, improves in the epicardial coronary arteries, increases exercise tolerance in patients with coronary artery disease, angina pectoris. Reduces pressure in the pulmonary circulation. Compared to nitroglycerin, Erinit has a slower, but longer lasting effect (up to 10 hours). When taken orally, the onset of the effect – after 30-45 minutes (with sublingual – after 15-20 minutes), duration – 4-5 hours.
