🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Nitroglycerin is converted in the body to nitric oxide (NO), which activates guanylate cyclase, leading to increased cyclic GMP. This results in relaxation of vascular smooth muscle, causing vasodilation. The primary effect is on venous vessels, reducing preload, but it also dilates coronary arteries and improves collateral blood flow to ischemic myocardium.
