肠外应用β_2肾上腺素能受体兴奋剂引起血清钾下降及糖代谢的改变早有报道。低血钾是β_2肾上腺素能受体兴奋剂导致心律失常的主要原因。口服型β_2肾上腺素能受体兴奋剂是一种应用广泛的剂型,其是否也会引起类似的变化,文献报道不一。本文作者观察常用的口服β_2肾上腺素能受体兴奋剂——特布 Parenteral β 2 adrenergic receptor agonists caused by serum potassium decline and changes in glucose metabolism have long been reported. Hypokalemia is the main cause of arrhythmia caused by β_2 adrenergic receptor agonists. Oral beta 2 adrenergic receptor agonist is a widely used form, whether it will cause similar changes in the literature reported different. The authors observed the commonly used oral β 2 adrenergic receptor agonist - Tebu
