Abstract

The invention belongs to the field of medicinal preparations, and relates to a solid preparation and a preparation method thereof, in particular to a solid preparation of clopidogrel or pharmaceutically acceptable salt of the clopidogrel as well as a preparation method thereof. The solid preparation is mainly prepared by mixing the clopidogrel or the pharmaceutically acceptable salt thereof with dimeticone and then processing the obtained mixture according to a conventional solid preparation processing method. By adopting the dimeticone, the invention has the advantages of preventing a dextroisomer of the clopidogrel from converting into a levoisomer, preventing the clopidogrel from being degraded into clopidogrel acid, being applicable to the formula and process for large-scale production of the preparation, solving the problem of drug degradation, improving drug stability, solving sticking and picking phenomena during the tabletting process, and improving product quality.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a solid preparation of clopidogrel or a pharmaceutically acceptable salt thereof and a preparation method thereof, mainly comprising tablets and capsules. Background technique [0002] The chemical name of Clopidogrel is (+)-(S)-α-(0-chlorophenyl)-6,7-dihydrothieno[3,2-c]pyridine-5(4H)-acetic acid Methyl ester (Formula I), the ester group of which is readily hydrolyzed to yield a biologically inactive acid (Formula II). Furthermore, the dextro isomer can be transformed into the almost inactive levoisomer (Chemical Formula III) under moist heat conditions. Its structure is as follows: [0003] [0004] [0005] [0006] 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 GP11b / 111a complex, so it can Inhibits...
