洋地黄与其他药物合用后,有些药物就改变了洋地黄在血中及心肌中的浓度;而有些药物则改变了心脏对洋地黄的敏感性。现扼要介绍这些药物合用时的交互作用。洋地黄与扩血管药合用实验和临床实践证明,血管扩张剂是通过减低阻抗来增加左心排血量,强心甙则增加心肌收缩力,因此血管扩张剂及强心甙联合应 When digitalis is used in combination with other drugs, some drugs change the concentration of digitalis in the blood and myocardium; while others alter the heart’s sensitivity to digitalis. Now briefly introduce the interaction of these drugs. Combination of digitalis and vasodilator experiments and clinical practice proved that vasodilator is to reduce the impedance to increase left ventricular output, cardiac glycosides increase myocardial contractility, vasodilators and cardiac glycosides should be combined
