[The influence of saralasine on blood pressure and renal function in Bartter's syndrome and decompensated hepatic cirrhosis (author's transl)].

Infusion of the angiotensin-II-antagonist saralasine led in one patient with Bartter's syndrome and one patient with decompensated hepatic cirrhosis, both of whom had a markedly raised plasma renin activity, to a fall in systolic and diastolic blood pressure. The results indicate that in normotensive patients a raised angiotensin II concentration in blood is haemodynamically important for the level of blood pressure if plasma renin activity is raised. In normotensives with normal plasma renin activity saralasine in the usual dosage (4.2 mug/kg-min) does not influence the blood pressure.
