title: Hypotensive action of an intra-nasally applied angiotensin II-antagonist.
abstract: Intranasal administration of the specific angiotensin II-antagonist (1-NSuc-5-Val-8-Phg) A II was investigated in anaesthetized rats with different forms of experimentally elevated blood pressure. Renin- or angiotensin II-induced blood pressure increases were markedly reversed by the angiotensin II-antagonist applied intra-nasally. In rats with acute accelerated elevation of blood pressure the analogue induced also a significant decrease. No change could be observed in rats with chronic renal hypertension.
