近二十年来,在发展控制心肌缺血症群、高血压以及心律失常的药物方面,取得了一些重大的进展。其中许多药物对这三种疾患均呈有良好疗效。例如,α-阻滞剂能缓解心绞痛,降低血压,并对某些心律失常亦有效。同样,苯并呋喃衍化物[如乙胺碘呋酮(amio-darone)]是强力抗心律失常、抗心绞痛药物,而且通过血管扩张也降低动脉压。慢通道抑 In the past two decades, some major advances have been made in the development of drugs to control the population of myocardial ischemia, hypertension and arrhythmia. Many of these drugs show good efficacy in all three conditions. For example, alpha-blockers can relieve angina, lower blood pressure, and are also effective in certain arrhythmias. Likewise, benzofuran derivatives [such as amio-darone] are potent anti-arrhythmic, anti-anginal drugs and also reduce arterial pressure through vasodilation. Slow channel
