[The hypertensive effect of adyston and etilefrin. Comparative animal experimental studies].

According to the results obtained under the described conditions it can be stated that after i.v. administration Adyston induces a dose-dependent rise in systolic and diastolic blood pressure, in comparison with etilefrin the new product Adyston shows a greater potency in rising the systolic and diastolic blood pressure; Adyston induced rise of blood pressure is in general of longer duration in comparison with that induced by etilefrin, it is interesting that in the dose of 0.01 mg/kg Adyston increases the arterial blood pressure but at the same time slightly decreases the heart rate; this is not the case after administration of etilefrin which at the same dose increases both arterial blood pressure and heart rate.
