Abstract

The invention provides a compound preparation of irbesartan hydrochlorothiazide and a preparation method thereof. The composite preparation comprises a tablet core, which includes the following ingredients (by weight): 150.0 parts of irbesartan, 12.5 parts of hydrochlorothiazide, 24.0-29.0 parts of microcrystalline cellulose, 10.0-17.0 parts of lactose monohydrate, 15.0-19.5 parts of croscarmellose sodium, 12.0-18.0 parts of hydroxypropyl methylcellulose, 8.0-11.0 parts of colloidal silicon dioxide and 7.0-9.0 parts of magnesium stearate. Compared with the equivalent weight of irbesartan and hydrochlorothiazide, microcrystalline cellulose and lactose monohydrate are also used as fillers in the tablet core of theinvention, and the sum of maximum total weights of microcrystalline cellulose and lactose monohydrate is less than 50, thus greatly reducing the amount of the fillers and lowering the material cost of the composite preparation; moreover, a proper amount of hydroxypropyl methylcellulose ensures the dissolution of the effective components.

Description

technical field [0001] The invention relates to the technical field of preparation of irbesartan-hydrochlorothiazide compound preparations, in particular to a compound preparation of irbesartan-hydrochlorothiazide and a preparation method thereof. Background technique [0002] Hypertension is the most common cardiovascular disease and a major public health problem worldwide. Irbesartan, namely 2-n-butyl-4-spirocyclopentane-1-[(2-(tetrazol-5-yl)biphenyl-4-yl)methyl]-2-imidazole Lin-5-one is a high-efficiency long-acting angiotensin II receptor antagonist, especially for the treatment of cardiovascular diseases such as hypertension and heart failure. Hydrochlorothiazide is a diuretic antihypertensive drug that causes activation of the sympathetic nervous system and the renin-angiotensin system, counteracts the antihypertensive effect, and lowers blood potassium levels. The combination of irbesartan and hydrochlorothiazide has a synergistic effect in the treatment of hyperten...
