摘要

The present invention relates to a stabilized oral preparation comprising clopidogrel bisulfate, and in particular the oral preparation herein further comprises starch and cellulose along with the crystalline form 1 or form 2 clopidogrel bisulfate, which is susceptible to moisture and produces hydrated product-related impurities when formulated into oral preparations, thus showing storage stability even in the same dosage form with the conventional preparations.
