Abstract

The invention relates to the technical field of pharmaceutical preparation, in particular to a chewable tablet containing imatinib mesylate and a method for preparing the same. The chewable tablet containing the imatinib mesylate consists of the principal imatinib mesylate, a filling agent, a flavour modifying agent, a glidant, an odor modifying agent, and an adhesive. The chewable tablet containing the imatinib mesylate can be applied to patients having difficulty in orally taking the common tablets, has good drug compliance, can be dissolved in saliva after chewing and being absorbed by oral or esophageal mucosa, and has high bioavailability. The chewable tablet not only has sweet taste and good mouthfeel, but also modifies penetrating odors and has flavor; the chewable tablet is convenient to take and carry around; and the chewable tablet is prepared by a direct tabletting method, and has good drug stability, simple production process, and low cost.

Description

technical field [0001] The invention relates to a pharmaceutical composition containing imatinib mesylate, more specifically, the invention relates to a chewable tablet of imatinib mesylate. The present invention also relates to a preparation method of the imatinib mesylate chewable tablet. Background technique [0002] Imatinib Mesylate is a derivative of aniline, and is a specific tyrosine kinase inhibitor (tyrosine kinases inhibitors, TKI) developed by Swiss Novartis. On May 10, 2001, imatinib oral capsule preparation entered the US FDA’s express approval channel with a breakthrough anti-tumor mechanism, and it is used for the treatment of α-interferon-failed embryonic crisis, chronic disease and accelerated disease.
