Terbutaline(下简称 TBT)的化学名为1-(3,5(-二羟苯基)-2-(叔-丁氨基)乙醇。化学上与异丙肾上腺素,orciprenaline,salbutamol 以及 isoe-tharinle 相关,为一新的气管扩张药。药理研究表明,TBT 主要作用于支气管平滑肌的β2-受体,并可保护术麻醉豚鼠对抗组织胺诱发的支气管痉挛,因而具有支气管扩张作用。实验和临床研究表明,在口服或吸入途径给药时,TBT 的支气管扩张的疗效可与 orciprenaline及 salbutamol 相比拟,TBT 的作用更为持久,这
Terbutaline (TBT for short) has the chemical name 1- (3,5 (-dihydroxyphenyl) -2- (tert-butylamino) ethanol and is chemically related to isoproterenol, orciprenaline, salbutamol and isoe-tharinle , A new tracheal dilation drug pharmacological studies have shown that TBT mainly acts on β2-receptors in bronchial smooth muscle and protects guinea pigs from anesthetizing induced bronchospasm and thus has bronchodilatory effects in experimental and clinical studies , Bronchodilator efficacy of TBT is comparable to orpharenaline and salbutamol when administered orally or by inhalation, and the effect of TBT is more sustained
