What is the therapeutic classification of Isosorbide Mononitrate?

Isosorbide Mononitrate belongs to the therapeutic classification of Long-Acting Nitrates, a subclass of vasodilators. This medication is primarily used in the treatment of angina pectoris, as it works by relaxing the blood vessels, allowing for improved blood flow and reduced heart workload. Its mechanism of action primarily involves the conversion to nitric oxide, which dilates both veins and, to a lesser extent, arteries.

Long-acting nitrates, such as Isosorbide Mononitrate, are particularly beneficial because they provide a sustained effect on vasodilation that helps prevent angina attacks when taken regularly. This distinguishes them from other classes of cardiovascular medications.

In contrast, alpha/beta adrenergic blockers function by blocking adrenergic receptors to lower heart rate and blood pressure, while calcium channel blockers primarily work by inhibiting calcium entry into cells, leading to muscle relaxation and decreased vascular resistance. Antihypertensives encompass a broader range of drug types aimed at lowering blood pressure, but Isosorbide Mononitrate is specifically aimed at preventing angina rather than being classified under antihypertensive agents.
