pressor responses caused by each of the active forms of angiotensin could be substantially reduced by pretreatment with the specific angiotensin receptor antagonist [ sar1 , thr8 ] ang ii ( sarthran ) , suggesting either that these ligands are acting at multiple receptors for ang ii and its fragments , which are all blocked by sarthran , or that the ligands are acting at a common receptor site .
