A class of 1-phenyl imidazol-2-one biphenylmethyl compounds is described for use in treatment of circulatory disorders. Compounds of particular interest are angiotensin II antagonists of the formula
1
wherein each of R
1
, R
2
and R
3
is independently selected from hydrido, alkyl, alkoxy, cyano, halo, hydroxy, carboxyl, alkoxycarbonyl, formyl and acetyl; alkylcarbonyl and haloalkylcarbonyl; with the proviso that at least one of R
1
, R
2
and R
3
must be a substituent other than hydrido, and with the further proviso that when each of R
1
and R
3
is hydrido, then R
2
cannot be chloro; wherein R
4
is hydrido; wherein R
5
is alkyl; and wherein R
6
is tetrazolyl; or a stereoisomer 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.
