The angiotensin type 1 (AT1) receptor antagonist, losartan (orally administered), decreases vasoconstrictor effects of angiotensin II (Ang II). Oral losartan is converted into the active metabolite, Exp3174, which causes most of the antagonistic effects. Effects of losartan as such have not been studied after its intra-arterial administration in humans. Therefore, we investigated the effects of both intra-arterially and orally administered losartan on AT1-receptor-mediated vasoconstriction.
