Isosorbide Mononitrate Tablets are a prescription medicine that belongs to the nitrate class of drugs, primarily used for heart-related conditions.

Here are the key points:

• Main Use: Mainly prescribed to prevent chest pain (angina) caused by coronary artery disease. They may also be used to improve heart function in certain cases of heart failure.

• How It Works: Isosorbide mononitrate relaxes and widens blood vessels, which reduces the workload on the heart and improves the supply of blood and oxygen to the heart muscle, helping prevent angina attacks.

• Administration: Taken orally, usually once or twice daily, depending on the prescribed schedule. It is designed for long-acting effect, so timing and spacing of doses are important to maintain effectiveness and prevent tolerance.

• Common Side Effects: Headache, dizziness, flushing, lightheadedness, and sometimes low blood pressure, especially when standing up suddenly.

• Serious Concerns: Rarely, it may cause severe hypotension, rapid heartbeat, or allergic reactions. Immediate medical attention is needed if severe symptoms occur.

• Precautions:

  • Should not be combined with certain erectile dysfunction medications (like sildenafil, tadalafil, vardenafil) due to risk of dangerous blood pressure drop.

  • Caution is needed in patients with low blood pressure, anemia, glaucoma, or recent head injury.

  • Continuous use without breaks may lead to tolerance, reducing effectiveness.

• Storage: Store at room temperature, away from moisture, heat, and direct sunlight.
