[pharmacological action] it has ephedrine like effect, which can increase blood pressure of anesthetized cat, enhance the contraction of blink membrane, strengthen the effect of adrenaline on blood pressure and uterus, strengthen the contraction of eutopic uterus of cat or rabbit, inhibit the contraction of small intestine and dilate coronary artery. In addition, it can increase the tension of striated muscle and enhance the excitability of spinal cord reflex, which may be related to the excitability of central nervous system. After adrenalectomy, its effect can still be maintained. It has no effect on ganglion, no enhancement effect on cocaine, and no significant effect on the preparation of nerve striated muscle in cat or rat. Although its effect is similar to ephedrine, its intensity is weak. When the mice were subcutaneously injected with more than 600 mg / kg, the inhibition and ataxia appeared, but the mice did not die. When the dose was 50-100 mg / kg, the frog was excited and the striated muscle tension was increased. When the dose was 200 mg / kg, the frog was killed. There was no significant change after subcutaneous injection of 50 mg / kg. In the early years, it was considered to be a kind of muscle poison, which could cause frog muscle rigidity and inhibit heart muscle in a large dose; if injected intravenously into rabbits, it could cause myocardial inhibition or even paralysis, gradually reduce blood pressure, and eventually the animals died of spasm.
