Which condition can nitrates be prescribed to alleviate?

Nitrates are primarily prescribed to relieve angina pectoris, which is chest pain or discomfort that occurs when the heart muscle does not get enough oxygen-rich blood. Nitrates work by relaxing and widening blood vessels, increasing blood flow to the heart, and reducing the workload on the heart. This is particularly beneficial during episodes of angina, as it helps alleviate the pain and symptoms associated with decreased blood flow.

In the context of treatment, while nitrates can have some effect in other conditions related to the cardiovascular system, their main and most effective use is in the management of angina. The mechanism of action allows for immediate relief of angina symptoms by reducing myocardial oxygen demand and enhancing oxygen supply through vasodilation.

In contrast, although nitrates may have some indirect benefits in conditions like hypertension or coronary artery disease due to their vasodilatory effects, they are not primarily indicated for those conditions in the same way that they are for angina.
