What Is Imdur?
Imdur, containing the active ingredient isosorbide mononitrate, is a long-acting nitrate medication used primarily to prevent episodes of chronic angina pectoris (chest pain) caused by coronary artery disease. Imdur works by relaxing and widening blood vessels, improving oxygen delivery to the heart and reducing cardiac workload.
Key Medical Uses of Imdur Tablets
Imdur tablets are prescribed for:
| Condition | Therapeutic Effect |
|---|---|
| Chronic angina pectoris | Prevents chest pain by improving blood flow |
| Coronary artery disease (CAD) | Reduces strain on the heart |
| Adjunctive therapy post-heart attack | Supports cardiac recovery and oxygen delivery |
Note: Imdur is for preventing angina episodes, not for relieving acute chest pain.
Warnings and Precautions Before Taking Imdur
- Avoid Use With Erectile Dysfunction Medications: Combining Imdur with phosphodiesterase inhibitors (like sildenafil or tadalafil) may cause life-threatening drops in blood pressure.
- Not for Hypotensive Patients: Imdur may cause significant low blood pressure. Patients with hypotension should be cautious.
- Allergy Caution: Individuals allergic to nitrates or nitrites must avoid Imdur.
