Which medication is commonly used to treat chest pain related to angina?

Nitroglycerin is a medication that is primarily used to relieve chest pain associated with angina, which is a condition characterized by reduced blood flow to the heart muscle, often leading to discomfort or pain. Nitroglycerin works by dilating the blood vessels, improving blood flow and oxygen supply to the heart, which alleviates the pain. It acts quickly and can be administered sublingually (under the tongue) for rapid relief during an angina attack.

Other medications listed, while useful for various purposes, do not specifically target chest pain from angina in the same effective manner. For instance, ibuprofen is a nonsteroidal anti-inflammatory drug good for reducing pain and inflammation but does not address the underlying issue of cardiac ischemia. Acetaminophen serves as a general pain reliever and fever reducer but similarly lacks the specific action needed for angina. Aspirin may be used in the context of heart conditions to prevent blood clots but is not directly used to relieve angina symptoms like nitroglycerin is.
