Embodiment 1

[0063] Embodiment 1: Clopidogrel bisulfate aspirin tablet prescription (in 1000 tablets)

[0064]

[0065] Preparation:

[0066] (1) Preparation of clopidogrel hydrogen sulfate mixed granules: 97.875g of clopidogrel hydrogen sulfate, 60g of mannitol, 60g of microcrystalline cellulose and 2.5g of F-Melt were added to the hopper and mixed; dry granulation; Granules, the sieve mesh number is 24 orders; The clopidogrel hydrogen sulfate granules prepared are added in the mixer, and the F-Melt of 2.5g is added to mix, and the clopidogrel hydrogen sulfate total mixing granules are obtained;

[0067] (2) Prepare aspirin blend powder: add 75g aspirin, 55g microcrystalline cellulose and 1.0g stearic acid into the hopper and mix to prepare aspirin blend powder;

[0068] (3) The clopidogrel bisulfate blended granules and the aspirin blended powder were respectively added to the two hoppers of the double-layer tablet press, and tableted.

Abstract

The invention provides a pharmaceutical composition of clopidogrel hydrogen sulfate and an acetylsalicylic acid tablet and a preparation method thereof, belonging to the field of pharmaceutical preparation. According to the pharmaceutical composition of clopidogrel hydrogen sulfate and the acetylsalicylic acid tablet provided by the invention, F-Melt is added into the formula, so that the flowability of materials is improved and the materials are uniformly mixed; and meanwhile, clopidogrel hydrogen sulfate and the acetylsalicylic acid tablet are respectively pressed into double-layer tablets, so that the two components are prevented from interacting, thereby benefiting the safety of clinical medication and the stability in the storage process.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a pharmaceutical composition of clopidogrel bisulfate aspirin tablets and a preparation method thereof. Background technique [0002] Clopidogrel hydrogen sulfate, the chemical name is 2-(2-chlorophenyl)-2-(6,7-dihydrothieno[3,2-c]pyridin-5-yl)acetate methyl ester hydrogensulfate, The chemical structural formula is: [0003] [0004] Clopidogrel is a platelet aggregation inhibitor that selectively inhibits the binding of adenosine diphosphate (ADP) to its platelet receptor and the subsequent ADP-mediated activation of the glycoprotein GPlllb / llla complex. Inhibits platelet aggregation. It can also block the platelet aggregation caused by other agonists through the release of ADP. [0005] Both aspirin and clopidogrel bisulfate have the effect of inhibiting platelet aggregation, the combination of the two can significantly enhance the anti-platelet activity, and ca...
