Nitroglycerin – Overview
**Nitroglycerin, also known as Nitroglycerine, is a medication primarily used to alleviate chest pain in conditions such as angina pectoris or heart attacks. It belongs to the category of nitrates and works by dilating the blood vessels, consequently reducing the workload on the heart and improving blood flow to the heart muscle.
**
Active Ingredients
**The key active ingredient in Nitroglycerin is, as the name suggests, nitroglycerin itself. This potent compound is responsible for the vasodilatory effects of the medication, leading to improved blood flow and decreased chest pain.
**
Pharmacological Properties
**Nitroglycerin acts as a vasodilator by releasing nitric oxide in the smooth muscle cells of blood vessels. This causes relaxation of the blood vessels, leading to increased blood flow. By dilating the coronary arteries, nitroglycerin enhances oxygen supply to the heart muscle, reducing the workload on the heart.
**
Indications
**Nitroglycerin is commonly prescribed for the following indications:
– Relief of acute chest pain associated with angina pectoris
– Prevention of chest pain before activities that may trigger angina
– Treatment of congestive heart failure in combination with other medications
