What drug class is isosorbide mononitrate in?
Isosorbide mononitrate belongs to the nitrate drug class—specifically, organic nitrates. These medicines work as vasodilators by increasing nitric oxide availability, which relaxes blood vessels and improves blood flow [1].
What does isosorbide mononitrate get prescribed for?
Because it’s an organic nitrate, isosorbide mononitrate is commonly used for angina (chest pain) to prevent attacks, and it may also be used in other settings related to ischemic heart disease depending on the product label and clinician judgment [1].
How is it different from other nitrate forms?
Isosorbide mononitrate is a nitrate medication, but it’s not the same as nitroglycerin. Nitroglycerin is another common nitrate drug, typically used for faster relief of angina in many formulations, while isosorbide mononitrate is often used for longer-term prevention (availability can vary by formulation) [1].
Isosorbide mononitrate vs. isosorbide dinitrate—are they the same class?
Yes. Isosorbide mononitrate and isosorbide dinitrate are both organic nitrates. The difference is in the chemical form (mononitrate vs dinitrate), but they still fall under the same nitrate vasodilator drug class [1].
Key cautions patients ask about with nitrate drugs
Nitrate medicines share some common safety concerns, including significant blood-pressure lowering. Patients are typically warned against using PDE-5 inhibitors (like sildenafil or tadalafil) at the same time, because the combination can cause dangerous hypotension. This is a class-related nitrate warning seen across organic nitrate products [1].
