Erynit tablets is an effective and safe medication that helps to reduce the risk of angina attacks and can offer long-term relief from the pain and discomfort associated with angina.

Erynit tablets Pharmacodynamics
A venous vasodilator, has an anti-anginal effect. Stimulates the formation of nitric oxide in the vascular wall, which is an endothelial relaxing factor. Reduces preload (dilation of peripheral veins and reduction of blood flow to the right atrium) and post-load (PPS) on the heart; reduces myocardial oxygen demand.
Restores blood flow through small endocardial vessels, improves epicardial coronary arteries, increases exercise tolerance in patients with coronary heart disease (CHD), angina pectoris.
In heart failure helps unload myocardium by reducing the preload. Reduces the pressure in the small circle of the circulation.
Compared with nitroglycerin, it has a slower but longer action (up to 10 hours). When taken orally, the beginning of the effect – after 30 – 45 minutes (when sublingual – after 15 – 20 minutes), the duration – 4 – 5 hours.
