Nitroglycerin Pharmacodynamics
Peripheral vasodilator with predominant effect on the venous vessels. The action of nitroglycerin is mainly related to reduction of myocardial oxygen demand by reducing preload (dilation of peripheral veins and reduction of blood flow to the right atrium) and postload (reduction of total peripheral vascular resistance).
It has a central inhibitory effect on the sympathetic vascular tone, inhibits the vascular component of pain syndrome formation. Causes meningeal vasodilation, which explains the headache when using it.
When using sublingual forms, an angina attack usually stops after 1.5 min, hemodynamic and antianginal effect lasts from 30 to 60 min.
