Pharmacological properties
Pharmacodynamics
The pharmacological effect of thiazotonic acid is due to its anti-ischemic, membrane-stabilizing, antioxidant, and immunomodulating effects.
The effect of the preparation is realized due to the enhancement of compensatory activation of anaerobic glycolysis and activation of oxidation processes in the Krebs cycle with preservation of the intracellular pool of adenosine triphosphate (ATP). The presence in the structure of the thiazotonic acid molecule of a thiol sulfur group, which has oxidative-reductive properties, and a tertiary nitrogen atom that binds excess hydrogen ions, leads to the activation of the antioxidant system. The strong reducing properties of the thiol group cause a reaction with active forms of oxygen and lipid radicals. The reactivation of anti-radical enzymes - superoxide dismutase, catalase, and glutathione peroxidase - prevents the formation of active oxygen forms.
The effect of thiazotonic acid leads to the inhibition of lipid oxidation processes in ischemic areas of the myocardium, a decrease in the sensitivity of the myocardium to catecholamines, prevents the progressive suppression of the contractile function of the heart, and contributes to the stabilization and reduction of the area of necrosis and ischemia of the myocardium. The improvement of the rheological properties of blood is carried out due to the activation of the fibrinolytic system. The improvement of metabolic processes in the myocardium, the increase in its contractile ability, and the promotion of normalization of heart rhythm make it possible to recommend thiazotonic acid for the treatment of patients with various forms of ischemic heart disease.
In parallel with the use in cardiology, thiazotonic acid is used in the treatment of liver diseases and other internal organs, taking into account its high hepatoprotective properties. The preparation prevents the destruction of hepatocytes, reduces the degree of fatty infiltration and the spread of centrilobular necrosis of the liver, promotes the processes of reparative regeneration of hepatocytes, normalizes protein, carbohydrate, lipid, and pigment metabolism in them. It increases the rate of synthesis and secretion of bile, normalizes its chemical composition.
