Abstract

The invention provides a clopidogrel hydrogen sulfate tablet medicine composition and a preparation method thereof. Magnesium aluminum silicate is adopted in a prescription, so that the material flowability can be improved, deliquescence of medicines can also be effectively prevented, a risk that clopidogrel is degraded to form clopidogrel acid due to moisture absorption can be reduced, and more stable quality can be achieved. The preparation method comprises the following steps: firstly preparing pill cores, and then directly spraying a clopidogrel hydrogen sulfate solution on the pill cores by virtue of fluidized bed coating for performing granulation. By adopting the clopidogrel hydrogen sulfate tablet medicine composition provided by the invention, the mixing uniformity of the medicines can be significantly improved; and moreover, the sticking problem of clopidogrel can be effectively solved, the appearance characteristics of products can be improved, the product yield can be improved, and the requirements for industrial large-scale production can be better met.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a pharmaceutical composition of clopidogrel bisulfate 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 an inducible platelet aggregation inhibitor that acts by inhibiting the binding of adenosine monophosphate to its receptors. By inhibiting platelet aggregation, it reduces the chance of arterial blockage, achieves the effect of preventing stroke and heart attack, and can effectively treat and prevent atherosclerosis. [0005] It has been reported in the literature that clopidogrel bisulfate oral tablets are easily degraded to clopidogrel acid during storage, especially in wet conditions; and the interaction between clopidogrel a...
