What medication is commonly used to relieve chest pain associated with angina?

Nitroglycerin is the preferred medication for relieving chest pain associated with angina because it acts as a potent vasodilator. By relaxing the smooth muscles of blood vessels, nitroglycerin increases blood flow, particularly to the heart muscle, which can alleviate the ischemic pain experienced during angina episodes. It works rapidly, often providing relief within minutes, making it especially effective for managing acute episodes of chest pain.

In contrast, aspirin is an antiplatelet agent that helps prevent blood clots but does not directly relieve chest pain. Beta blockers and calcium channel blockers are often used in the long-term management and prevention of angina by reducing myocardial oxygen demand, but they do not provide immediate relief of acute chest pain. Therefore, nitroglycerin is specifically recognized for its fast-acting properties that address the symptoms of angina swiftly.
