Pharmacodynamics and pharmacokinetics

Pharmacodynamics

Antianginal drug, belongs to the group of peripheral vasodilators, which affect mainly venous vessels. Mechanism of action nitroglycerin based on the ability to release nitrogen oxidebeing an endothelial relaxing factor. Based on the action of nitric oxide (increases the concentration of cyclic guanosine monophosphatase inside the cells), the penetration of calcium ions into smooth muscle cells is slowed, which causes relaxation of the smooth muscles of the vascular wall and their expansion. As a result, preload (venous return to the heart) and afterload (resistance in a large circle of blood circulation) are reduced, which reduces the oxygen demand of the heart muscle. Reducing the return of venous blood reduces filling pressure, normalizes the supply of blood to the subendocardial layers and pressure in the pulmonary circulation.

As a result of the expansion of the coronary vessels, redistribution of coronary blood flow occurs in the area with insufficient blood supply. Nitrospray (nitroglycerine) lowers the sympathetic tone of blood vessels, while the vascular component of the pain syndrome is inhibited. The drug relaxes the smooth muscle cells of the bronchi, gall bladder, urinary tract, esophagus, bile ducts, intestines and their sphincters.
