What medication is commonly given to a patient suffering from angina pectoris?

Nitroglycerine is commonly administered to patients suffering from angina pectoris because it is a potent vasodilator that helps relieve chest pain by increasing blood flow to the heart muscle. Angina pectoris typically occurs when the heart muscle does not receive enough blood due to narrowed coronary arteries. By dilating the blood vessels, nitroglycerine reduces the workload on the heart and alleviates the symptoms associated with angina.

Aspirin is often used to prevent blood clots in cardiovascular patients but does not directly relieve angina pain. Beta-blockers are effective for managing angina over the long term by reducing the heart's workload, but they do not provide immediate relief of an angina episode as nitroglycerine does. Antidepressants may be used for patients dealing with anxiety or depression, which can occur in patients with heart disease, but they are not specific treatments for angina pectoris. Therefore, nitroglycerine stands out as the most appropriate and effective medication for acute relief during an angina episode.
