What condition do nitroglycerin medications primarily treat?

Nitroglycerin medications primarily treat angina pectoris, which is chest pain or discomfort that occurs when the heart muscle doesn’t get enough oxygen-rich blood. Nitroglycerin works as a nitrate, which helps to relax and widen the blood vessels, improving blood flow to the heart. This vasodilation decreases the heart's workload and reduces the oxygen demand of the heart muscle, effectively alleviating the symptoms of angina.

While nitroglycerin can have effects related to other heart conditions, such as heart failure or hypertension, its primary and most well-established role is in the management of angina pectoris. It is often used as a first-line treatment for episodes of chest pain, and it can also be utilized in various formulations for both acute relief and long-term management of angina symptoms.
