Isosorbide is primarily used for which condition?

Isosorbide is primarily used for the management of angina, which is chest pain that occurs due to insufficient blood flow to the heart. It is a type of nitrate that works by dilating blood vessels, improving blood flow, and reducing the workload of the heart. This mechanism helps alleviate the symptoms of angina by ensuring that the heart receives an adequate supply of oxygen during physical activity or stress.

Nitrates like isosorbide are particularly effective in treating angina because they can manage the episodes by preventing or reducing the frequency of chest pain. When the heart is better supplied with oxygen, patients experience relief from the strain and discomfort associated with angina.

While hypertension, edema, and diabetes are significant medical conditions, isosorbide is not primarily indicated for these issues. Other medications are typically prescribed to manage blood pressure, fluid retention, or blood glucose levels instead. Thus, isosorbide's primary role in angina treatment highlights its importance in cardiovascular health.
