Explanation:
Detailed explanation-1: -Nitroglycerin remains a first-line treatment for angina pectoris and acute myocardial infarction. Nitroglycerin achieves its benefit by giving rise to nitric oxide, which causes vasodilation and increases blood flow to the myocardium.
Detailed explanation-2: -It can relieve angina quickly. That’s because it can widen the coronary arteries, which bring blood and oxygen to the heart. This improves blood flow to the heart muscle, which relieves symptoms.
Detailed explanation-3: -Nitroglycerin is a vasodilatory drug used primarily to provide relief from anginal chest pain. It is currently FDA approved for the acute relief of an attack or acute prophylaxis of angina pectoris secondary to coronary artery disease.
