It has both nitrate-like and ATP-sensitive potassium channel activator properties, and is used for the prevention and treatment of angina pectoris. It has a role as a vasodilator agent and a potassium channel opener. It is a pyridinecarboxamide and a nitrate ester. It is functionally related to a nicotinamide."}]
