Embodiment 1

[0036] Calculate and weigh each component of the corresponding prescription amount, and then prepare the alisartan medoxomil indapamide preparation according to the following preparation process, and the specific prescription composition is as follows.

[0037]

[0038] Concrete preparation process is as follows:

[0039](1), Alisartan medoxomil and polyvinylpyrrolidone weighing prescription quantity are dissolved in appropriate methylene chloride, dehydrated alcohol, are made into medicine solution, and the crospovidone of prescription quantity is placed in fluidized bed, The drug solution is sprayed into the fluidized bed for spray granulation and drying, and then the prescribed amount of lactose, microcrystalline cellulose, crospovidone and stearic acid are added for mixing to obtain the total mixed granules of alisartan medoxomil.

[0040] (2), add the prescription amount of povidone to absolute ethanol and purified water, stir until completely dissolved, add the prescr...

Abstract

The invention belongs to the technical field of pharmaceutical preparations, and relates to a compound antihypertensive pharmaceutical composition and a preparation method thereof, in particular to a pharmaceutical composition of allisartan medoxomil and / or salt thereof and indapamide and a preparation method thereof.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and relates to a compound antihypertensive pharmaceutical composition and a preparation method thereof, in particular to a pharmaceutical composition of alisartan medoxomil and / or its salt and indapamide and a preparation method thereof. Background technique [0002] Allisartan Isoproxil, 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. Chinese patents CN106188012A, CN104610232A, CN109320501A, CN109694369A, CN105232489A, and CN107441497A respectively s...
