As a long-acting nitrate, it produces a vasodilator effect on peripheral veins and arteries decreasing oxygen demand on the heart. Isosorbide mononitrate also increases blood flow to help prevent episodes of chest discomfort.
Through Klarity, eligible U.S. adults can consult with licensed providers who assess medical history, existing conditions, and concurrent medications to determine if isosorbide mononitrate is appropriate.

Compared with other antianginal medications:
| Medication | Class | Dosing | Notable Features |
| Isosorbide Mononitrate | Long-acting nitrate | 30–120 mg ER once daily | prevents angina, tolerance issues |
| Nitroglycerin | Short-acting nitrate | Sublingual, repeat doses up to three times at 5 minute intervals | Rapidly relieves acute chest pain |
| Beta-blockers (e.g., metoprolol) | Beta-blocker | 1–2x/day oral | Reduces heart rate and oxygen demand, first-line for stable angina |
| Calcium Channel Blockers | CC blocker | Daily oral | Controls blood pressure and chest pain |
| Amlodipine | CCB | Once daily | Adds vasodilation without increasing preload |
Nitrates like isosorbide mononitrate are often used in combination with beta-blockers or CCBs. Compared to short-acting nitrates, long-acting forms are for prevention—not for acute relief. Tolerance and hypotension risk require careful dosing and monitoring.
