Background and objective: Rhomotoxin, the active constituent of Rhododendron molle belonging to Ericaceae, has the effects of decreasing blood pressure and slowing heart rate. These effects can exacerbate and remain 0.5-1 hour after drug withdrawal, which is prone to cause lower blood pressure even shock.

背景与目的八厘麻毒素(rhomotoxin，RTX)系从植物杜鹃花科羊踯躅成熟果实中提取的有效成份，具有较强的降压、减慢心率作用，但其降压作用在停药后0.5-1小时仍继续加深，易引起降压过度而导致休克，同时血中浓度检测困难，不易监控，临床上应用较难掌握。
