🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Nitroglycerin is a nitrate that is converted in the body to nitric oxide (NO), which activates guanylate cyclase. This leads to increased cyclic GMP (cGMP) levels, causing smooth muscle relaxation and vasodilation. The vasodilation predominantly affects veins, reducing preload and cardiac workload. At higher doses, it also dilates arteries, reducing afterload. This results in decreased myocardial oxygen demand and improved coronary blood flow, relieving angina.
