Pharmacological action

Cardiket is a vasodilator.

Pharmacodynamics

Isosorbide dinitrate causes relaxation of the smooth muscle wall of blood vessels, thus inducing vasodilation. Isosorbide dinitrate acts as a peripheral vasodilator, affecting both arteries and veins. These effects contribute to the deposition of venous blood and reduce venous return to the heart, reducing end dBP and left ventricular volume (reduce preload).

A long-acting cardiket is characterized by a combination of rapid onset of effect and duration of action.

The advantages of the drug are determined by the fact that the Active ingredient contained in the Cardiket®tablet of prolonged action quickly enters the bloodstream. As a result, the drug provides a rapid onset of effect in the treatment of angina pectoris and retains its protective effect for a long time.

Pharmacokinetics

When taken orally, isosorbide dinitrate is rapidly absorbed. Oral bioavailability is 22% (the effect of “first pass” through the liver). The onset of action is in 15-30 minutes, the_cmax of the substance in the blood plasma is reached in 15 minutes — 1-2 hours. As a result of passing through the liver, isosorbide dinitrate is metabolized to form isosorbide-2-mononitrate and isosorbide-5-mononitrate, which have T_1/2of 1.5-2 and 4-6 hours, respectively. Both metabolites are pharmacologically active. It is excreted by the kidneys (almost entirely in the form of metabolites). Binding to plasma proteins is 30%.
