What Is Isosorbide Mononitrate SR Tablets 40 Mg?

Isosorbide Mononitrate SR Tablets 40 Mg is an extended-release oral nitrate designed to provide sustained protection against angina episodes.

It contains isosorbide mononitrate, a long-acting vasodilator that reduces the heart’s oxygen demand.

This formulation is intended for prevention — not for emergency chest pain relief.

It is commonly prescribed for:

• Chronic stable angina

• Coronary artery disease

• Ischemic heart conditions

According to international cardiovascular guidelines, nitrate therapy plays an established role in managing chronic angina when prescribed appropriately.

How Isosorbide Mononitrate SR Tablets 40 Mg Works

1. Nitric Oxide Release

The drug releases nitric oxide in vascular smooth muscle.

2. Vasodilation

Blood vessels widen, reducing preload and afterload.

3. Reduced Cardiac Oxygen Demand

The heart works more efficiently with less strain.

4. Sustained Effect

The SR formulation provides prolonged therapeutic action.
