Verapamil slows the movement of calcium through cells, which has two results. Firstly, it decreases the rate at which the heart beats. As a result, the heart uses less energy and the pain of angina is prevented or relieved. Secondly, it has a mild widening effect on blood vessels and therefore reduces blood pressure.
