Pharmacological properties
Pharmacodynamics
Nitrocor is a peripheral vasodilator that mainly affects the venous vessels. The action of nitroglycerin 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 - a decrease in total peripheral vascular resistance).
It has a central inhibitory effect on the sympathetic vascular tone, inhibits the vascular component of the formation of pain syndrome. It leads to the expansion of the meningeal vessels (this is the cause of headache when using it). An attack of angina pectoris when Nitrocor is applied under the tongue, as a rule, stops after 1.5 minutes, the time for maintaining the antianginal and hemodynamic effect is in the range of 30-60 minutes.
Pharmacokinetics
Nitroglycerin from the surface of the mucous membranes is absorbed completely and quickly. When the drug is taken under the tongue, the substance immediately enters the systemic circulation, its bioavailability is 100%.
The maximum plasma concentration in the blood is reached after 5 minutes.
Communication with blood plasma proteins - 60%. Has a large volume of distribution.
