Pharmaceutical composition of allisartan medoxomil or salt thereof and diuretic

Abstract

The invention provides the composition of the allisartan medoxomil and / or the salt thereof and the diuretic. The composition has a pharmaceutical prospect, and the composition realizes the antihypertensive synergistic effect by limiting the mass ratio of the allisartan medoxomil and / or the salt thereof to the diuretic, so that the antihypertensive effect is improved, and the adverse drug reaction is reduced.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, in particular, the scheme relates to a pharmaceutical composition of alisartan medoxomil or its salt and a diuretic. Background technique [0002] Alisartan medoxomil (CAS: 947331-05-7), chemical name: 2-butyl-4-chloro-1-[2'-(1H-tetrazol-5-yl)-1,1'-biphenyl -Methyl]-imidazole-5-carboxylic acid, 1-[(isopropoxy)-carbonyloxy]-methyl ester, trade name: Xinlitan, is a new type of angiotensin Ⅱ receptor antagonist . Chinese patent CN200680000397.8 discloses the structural formula of the allisartan medoxomil compound. The allisartan medoxomil is less toxic and has a better antihypertensive effect than similar products (such as losartan). Its antihypertensive effect. [0003] [0004] However, for the population with severe hypertension and / or with multiple risk factors, target organ damage or clinical disease, the administration of a single antihypertensive drug often cannot achieve the best the...
