[Angiotensin - a possible cause of acute renal failure (author's transl)]. 
The hypertensive action of angiotensin is purely brought about by peripheral vasoconstriction and may, thus, lead to reduced perfusion of vital organs, especially the kidneys.  The dangers of angiotensin in triggering off acute renal failure are illustrated by a case report in which this drug was administered to a comatose patient with hypovolaemic hypotension following barbiturate self-poisoning.
