救必应正丁醇提取物对不同状态下血压及心率作用研究结果表明,静脉注射本品对正常大鼠及夹闭颈总动脉升压大鼠均有显著降压作用,血压下降百分率尤以后者更为明显,持续时间更为长,且有减慢心率的作用。而对失血性低血压大鼠无明显影响,十二指肠灌注本品亦可使血压显著下降,而对心率无明显影响。提示本品具有明显降压和升压状态下减慢心率的作用。
The results of studies on blood pressure and heart rate under different conditions of salbutamol extract showed that intravenous injection of this product has a significant antihypertensive effect on normal rats and the clamping of common carotid artery in rats. Those who are more obvious, have a longer duration, and have the effect of slowing down their heart rate. There was no significant effect on hemorrhagic hypotensive rats, and duodenal perfusion of this product could also result in a significant decrease in blood pressure without a significant effect on heart rate. This product has the effect of slowing down the heart rate under significant pressure reduction and boosting conditions.
