Novel imidazole derivatives of the formula (I):
wherein R¹ is an optionally substituted alkyl group, R² and R³ are independently a group capable of forming anion or a group which can be changed thereinto, ring A is benzene ring optionally having, besides the group shown by R², further substituents, and X shows linkage of phenylene group and phenyl group directly or through a spacer whose atomic chain is not more than 2 and a salt thereof, show antagonistic actions to angiotensin II, thus being useful as therapeutics for cardiovascular diseases.
