Background Information 0005. It is known that co-administration of an angiotensin II receptor antagonist and a diuretic is an effective therapy for the prevention or treatment of hypertension (particularly treatment). These pharmaceutical compositions are described, for example, in WO89/6233, Japanese Patent Application Kokai No. Hei 3-27362 and the like. 0006. However, the effects of a pharmaceutical compo 0010 The compound of formula (I), a salt thereof and the Sition containing a specific angiotensin II receptor antago like are known compounds, for example, described in the nist, such as CS-866 ((5-methyl-2-oxo-1,3-dioxolen-4-yl)m- Specification of Japanese Patent Application Kokai No. Hei ethyl 4-(1-hydroxy-1-methylethyl)-2-propyl-1-2'-(1H 5-78328 etc. and the chemical name of the compound of tetrazol-5-yl)biphenyl-4-ylmethyl)imidazol-5-carboxylate) formula (I) is 4(1-hydroxy-1-methylethyl)-2-propyl-1-2'- (U.S. Pat.

The “pharmacologically acceptable salt” of the 0007 Considering that prevention and/or treatment of compound of formula (I), which is an active ingredient of hypertension are important, the present inventors investi this invention, includes an alkali metal Salt Such as Sodium gated combinations of various drugs and found that a Salt, potassium Salt or lithium Salt, an alkaline earth metal pharmaceutical composition containing a Specific angio Salt Such as calcium Salt or magnesium Salt, a metal Salt Such tensin II receptor antagonist, Such as CS-866, and one or as aluminum Salt, iron Salt, Zinc Salt, copper Salt, nickel Salt more diuretics exerts excellent anti-hypertensive effects and or cobalt Salt, or an amine Salt Such as ammonium Salt, hence may be useful as a preventative and/or therapeutic t-octylamine Salt, dibenzylamine Salt, morpholine Salt, glu agent for hypertension. cosamine Salt, phenylglycine alkyl ester Salt, ethylenedi 0008. The present invention provides a pharmaceutical amine Salt, N-methylglucamine Salt, guanidine Salt, diethy composition containing a specific angiotensin II receptor lamine Salt, triethylamine Salt, dicyclohexylamine Salt, N,N'- antagonist and one or more diuretics as the active ingredi dibenzylethylenediamine Salt, chloroprocaine Salt, procaine ents (particularly pharmaceutical compositions for prevent Salt, diethanolamine Salt, N-benzylphenethylamine Salt, pip ing or treating hypertension), the use of a specific angio erazine Salt, tetramethylammonium salt or tris(hydroxym tensin II receptor antagonist and one or more diuretics for ethyl)aminomethane Salt. An alkali metal Salt is preferable manufacturing the pharmaceutical compositions (particu and the Sodium Salt is particularly preferable. larly pharmaceutical compositions for preventing or treating 0012. The “pharmacologically acceptable ester' of the hypertension), a method for preventing or treating (particu compound of formula (I), which is an active ingredient of larly treating) diseases (particularly hypertension) by the this invention, is a compound esterified at the carboxyl administration of a specific angiotensin II receptor antago moiety of the compound of formula (I).
