Verapamil inhibits the transmembrane influx of calcium ions into the heart and vascular smooth muscle cell. The myocardial oxygen demand is lowered directly as a result of the effect on the energy consuming metabolic processes of the myocardial cell and indirectly due to a reduction of the afterload. Due to its effect on coronary vascular smooth muscle, verapamil enhances myocardial blood flow, even in post‐stenotic areas, and relieves coronary spasms. These properties contribute to the anti‐ischaemic and antianginal efficacy of verapamil in all types of coronary artery disease. |
