ISMO-20 (Isosorbide mononitrate-20)
ISMO 20 contains the active ingredient isosorbide-5-mononitrate. It belongs to a class of medicines known as organic nitrate vasodilators, meaning that they cause blood vessels to widen. Widening the blood vessels means that blood flow and blood pressure is improved, and so the heart does not need to do as much work and does not need as much oxygen.
ISMO 20 will help to reduce the number and severity of angina attacks (severe chest pains due to heart disease). ISMO 20 tablets are used to stop angina attacks from happening. They cannot be used to treat a sudden attack of angina. Your doctor will probably have prescribed another treatment for you to use for sudden attacks.
ISMO 20 is also used to treat heart failure (a disease of the heart with shortness of breath, tiring easily and swelling of the feet or legs due to fluid build up) and pulmonary hypertension (high blood pressure in the arteries and veins between the lungs and the heart).
Your doctor may have prescribed ISMO 20 for another purpose.
Ask your doctor if you have any questions about why ISMO 20 has been prescribed for you.
