pharmachologic effect

Peripheral vasodilator with a predominant effect on the venous vessels. Antianginal remedy. The mechanism of action is associated with the release of the active substance nitric oxide in the smooth muscles of the vessels. Nitric oxide activates guanylate cyclase and increases cGMP levels, which ultimately leads to relaxation of smooth muscle. Under the influence of glyceryl trinitrate, arterioles and precapillary sphincters relax to a lesser extent than large arteries and veins. This is partly due to reflex reactions, as well as less intense formation of nitric oxide from active substance molecules in the walls of arterioles.The action of nitroglycerin (glyceryl trinitrate) is mainly associated with a decrease in myocardial oxygen demand due to a decrease in preload (expansion of peripheral veins and a decrease in blood flow to the right atrium) and afterload (decrease in systemic vascular resistance). Promotes the redistribution of coronary blood flow to the ischemic subendocardial areas of the myocardium. Increases exercise tolerance in patients with coronary artery disease, angina pectoris. In heart failure, it contributes to the unloading of the myocardium, mainly by reducing the preload. Reduces pressure in the pulmonary circulation.In heart failure, it contributes to the unloading of the myocardium, mainly by reducing the preload. Reduces pressure in the pulmonary circulation.In heart failure, it contributes to the unloading of the myocardium, mainly by reducing the preload. Reduces pressure in the pulmonary circulation.

Pharmacokinetics

After oral administration, it is absorbed from the gastrointestinal tract, undergoes the first pass" effect through the liver.

With sublingual administration, this effect is absent, and the therapeutic concentration in the blood plasma is achieved within a few minutes.

It is metabolized in the liver with the participation of nitrate reductase.

From nitroglycerin metabolites, dinitro derivatives can cause severe vasodilation

perhaps it is they who determine the therapeutic effect of nitroglycerin (glyceryl trinitrate) when taken orally.

Plasma protein binding is 60%.

T1 / 2 after oral administration - 4 hours, with sublingual administration - 20 minutes, after intravenous administration - 1-4 minutes.

It is excreted mainly by the kidneys.
