💗 Isosorbide Mononitrate 10mg Tablet: Mild Yet Effective Prevention of Angina
💊 What is Isosorbide Mononitrate 10mg?
Isosorbide Mononitrate 10mg is a short-acting nitrate medication used to prevent angina pectoris (chest pain) associated with coronary artery disease. It works by relaxing and widening blood vessels, making it easier for blood and oxygen to reach the heart. This reduces the heart’s workload, preventing episodes of angina.
This low-dose formulation is often used:
-
In patients who are starting nitrate therapy
-
For dose titration
-
For those requiring less intense nitrate action or with lower tolerance

🧾 Summary
Isosorbide Mononitrate 10mg tablet is a low-dose, short-acting nitrate used to prevent angina symptoms in patients with heart disease. It works by widening blood vessels, reducing strain on the heart, and increasing oxygen delivery. While it is generally well-tolerated, side effects like headache, dizziness, or low blood pressure can occur, particularly when starting the medication. Monitoring blood pressure and symptom frequency is important. It should not be used for immediate relief of chest pain and should never be combined with erectile dysfunction medications. With proper use and monitoring, it provides effective relief from chest pain, improving daily activity and quality of life.
