Mechanism of action

Nicorandil is a potassium channel opener with dual mechanism of action: it activates ATP-sensitive potassium channels in coronary and peripheral blood vessels, causing vasodilation and reducing myocardial oxygen demand. Additionally, it possesses nitrate-like properties that contribute to its vasodilatory effects. This combination reduces both preload and afterload on the heart, improving coronary blood flow and myocardial perfusion.
