A class of N-substituted (.alpha.-imidazolyltoluyl)pyrrole compounds is described for use in treatment of circulatory disorders. Compounds of particular interest are angiotensin II antagonists of the formula ##STR1## wherein m is one; wherein R.sup.0 is selected from CH.sub.2 OH, CO.sub.2 H, CHO, CO.sub.2 CH.sub.3, CO.sub.2 C.sub.2 H.sub.5, CH.sub.2 OCH.sub.3, CH.sub.2 OCHOCH.sub.3 and CH.sub.2 --CO.sub.2 C.sub.2 H.sub.5 ; wherein R.sup.1 is selected from Cl, CF.sub.3, CHO, n-butyl, cyano, CO.sub.2 CH.sub.3 and CO.sub.2 CH.sub.2 CH.sub.3 ; wherein R.sup.2 is selected from methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, neopentyl, phenyl, benzyl, phenethyl, cyclohexyl, cyclohexylmethyl, cyclohexylethyl, propylthio, butylthio and hydroxyalkyl; wherein each of R.sub.3, R.sub.4, R.sup.6, R.sup.7, R.sup.9 and R.sup.10 is hydrido; wherein each of R.sup.5 and R.sup.8 is independently selected from hydrido, halo, nitro, trifluoromethyl, hydroxy, alkoxy, cyano, carboxyl, methoxycarbonyl with the proviso that at least one of R.sup.5 and R.sup.8 is an acidic group selected from CO.sub.2 H and tetrazolyl; or a tautomer thereof or a pharmaceutically-acceptable salt thereof. These compounds are particularly useful in treatment or control of hypertension and congestive heart failure.
