Abstract

The invention discloses a clopidogrel sulfate tablet and a preparation process thereof. The tablet contains compound of clopidogrel sulfate and polyvinylpolypyrrolidone, wherein the compound is prepared by the steps of dissolving clopidogrel sulfate in an alcohol solvent, adding polyvinylpolypyrrolidone, uniformly mixing and drying by spray. The clopidogrel sulfate and polyvinylpolypyrrolidone compound prepared by the process is capable of avoiding adhesion in the producing process and successfully solving the stability problem in clopidogrel sulfate preparing and storing processes, is simple in process, and is easy for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a solid oral preparation, in particular to a tablet containing clopyrrole bisulfate and a preparation process thereof. Background technique [0002] Clopidogrel bisulfate is a thienopyridine compound with a chemical structure similar to ticlopidine, which can selectively inhibit the binding of adenosine diphosphate to its platelet receptor and the subsequent ADP-mediated The activation of glycoprotein GPIIIb / IIIa complex has irreversible inhibition of platelet aggregation and is clinically used as an antithrombotic drug. Clopidogrel bisulfate is soluble in water, methanol, ethanol or glacial acetic acid, and very slightly soluble in acetone or chloroform; the current clinical dosage forms of clopidogrel bisulfate are mainly oral medicines with the trade names "Plavix" and "Shuaike". Tablets (the specification is 75mg clopidogrel) and oral tablets ...
