Abstract

The present invention relates to a solid preparation of clopidogrel hydrochloride and its preparation method. It is characterized by that in said sold preparation the palmitoleostearin and micropowder silica gel are added, and its preparation method adopts a grinding equivalent progressively-increasing method so as to raise the stability and safety of said solid preparation.

Description

[technical field] [0001] The invention relates to a solid preparation of medicine and a preparation method thereof, in particular to a solid preparation of clopidogrel sulfate and a method for preparing the solid preparation by a grinding equivalent increment method. [Background technique] [0002] Clopidogrel is an inducible platelet aggregation inhibitor that acts by inhibiting the binding of adenosine monophosphate to its receptors. Clopidogrel is an inactive prodrug that is metabolized by hepatic cytochrome P450 into an active metabolite to exert its drug effect. Patents FR2215948 and FR2530247 disclose that clopidogrel has significant anti-platelet aggregation and antithrombotic effects. Clopidogrel reduces the chance of arterial blockage by inhibiting platelet aggregation, achieves the effect of preventing stroke and heart attack, and can effectively treat and prevent atherosclerosis. [0003] Clopidogrel is usually given in its sulfate form. Its structure is as fol...
