Nicorandil 5 mg Tablets

Nicorandil contains a substance called nicorandil. This substance belongs to a group of medicines called "potassium channel activators". It works by relaxing blood vessels and increasing the blood flow and oxygen supply to the heart. Nicorandil is used to prevent chest pain (angina pectoris) and for long-term treatment of chest pain (stable angina pectoris).

Why is this medication prescribed?

Nicorandil belongs to a group of medicines called 'potassium channel activators'. It works by increasing the blood flow through the blood vessels of the heart. Nicorandil is used to stop and treat long-term chest pain (angina).

Indications and Usage

Angina is a pain that comes from the heart. It is usually caused by the narrowing of one or more of the arteries that supply blood to your heart. This narrowing reduces the blood supply to parts of your heart muscle. When your heart needs more blood and oxygen than can get through the narrowed arteries (for example, when you walk fast or climb stairs), you feel angina pain. Nicorandil works by relaxing (widening) your blood vessels. This increases the supply of blood and oxygen to your heart, and reduces the pain you feel. It can also reduce the risk of further heart conditions.

Mechanism of Action

Nicorandil, a vasodilator, is prescribed for the treatment and management of angina pectoris. The drug relaxes the blood vessels and alleviates the angina.


Nicorandil dilates arterioles and large coronary arteries by opening the potassium channels, and stimulates guanylate cyclase causing venous vasodilatation. It therefore reduces preload and afterload, and improves coronary blood flow.
Absorption: Absorbed well from the GI tract (oral); peak plasma concentrations after 30-60 min.
