心得安于1964年被介绍为一种有效的β-肾上腺素能拮抗剂。目前临床上已广泛地应用,常单独或与其它制剂联合使用治疗室性或室上性心律失常、心绞痛、阻塞性心肌病、原发性高血压及甲状腺机能亢进。对某些运动过度心脏综合征(Hyperkinetic heartsyndromes)、偏头痛、特发性震颤、焦虑、精神病和脓毒性休克患者亦有俾益。因为心得安能阻断β-肾上腺素能受体,依靠交感性兴奋的患者的心脏功能可被抑制。因此被认为是一种具有潜在性危险的药物,特别是对严重心脏病或 Ambivalence was introduced in 1964 as a potent β-adrenergic antagonist. Currently widely used in clinical practice, often alone or in combination with other agents used to treat ventricular or supraventricular arrhythmias, angina pectoris, obstructive cardiomyopathy, essential hypertension and hyperthyroidism. It is also beneficial for some patients with Hyperkinetic heart syndrome, migraines, essential tremor, anxiety, psychosis and septic shock. Because prednisone blocks beta-adrenergic receptors, heart function in patients who rely on sympathetic excitation can be suppressed. It is therefore considered a potentially dangerous drug, especially for serious heart disease or
