Which medication is used during an angina attack?

During an angina attack, the most effective treatment is GTN (glyceryl trinitrate) spray. GTN is a vasodilator, meaning it works by relaxing and widening blood vessels. This action helps to improve blood flow to the heart, which can relieve the chest pain associated with angina. When administered during an attack, GTN alleviates the symptoms quickly by reducing the workload on the heart and increasing the oxygen supply.

Oxygen is sometimes used in a clinical setting, but it is not specifically a first-line treatment for angina attacks. Aspirin can be beneficial for patients with angina in preventing clot formation, thereby addressing the risk of heart attacks, but it does not relieve the acute chest pain of an angina episode. Glucogel is primarily used for the treatment of hypoglycemia in diabetic patients and is not relevant to managing angina.
