Abstract

The invention relates to an acotiamide hydrochloride controlled release tablet and a preparation method thereof, and belongs to the field of medical preparations. The controlled release tablet comprises an acotiamide hydrochloride solid dispersion and pharmaceutical excipients, wherein the acotiamide hydrochloride solid dispersion comprises acotiamide hydrochloride, a polymer, a plasticizer and a lubricant b; and the pharmaceutical excipients include a controlled release material, a stabilizer, a disintegrating agent, an adhesive, a lubricant a and a coating material. The preparation method comprises the steps of firstly performing hot-melt extrusion on acotiamide hydrochloride to obtain the acotiamide hydrochloride solid dispersion; secondly adding the solid dispersion to the pharmaceutical excipients to prepare a mixture; thirdly, preparing the mixture into a tablet; and finally preparing the tablet into a coated tablet by using the coating material. According to the scheme, the early release degree of acotiamide hydrochloride is increased, the controlled release effect can last for 24 hours, and the tablet has very high stability; and in addition, the preparation method is simple in process and free of solvent residues, and other impurities are not introduced in the whole process, so that the preparation method is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to an acotiamide hydrochloride sustained-release tablet and a preparation method thereof, in particular to an acotiamide hydrochloride sustained-release tablet prepared by a hot-melt extrusion technology. Background technique [0002] Functional dyspepsia (FD) is the most common clinical functional gastrointestinal disease. The prevalence of FD in European countries is 20-30%. Domestic statistics show that FD patients account for about one-third of gastrointestinal specialist outpatients. The above is at a relatively high level, but there is no relevant specific drug on the market at present. [0003] Acotiamide is a new type of selective acetylcholinesterase inhibitor. Clinical trials have proven to be effective in the treatment of functional dyspepsia, and it is safe and effective. The drug can selectively block muscarinic M1 and M2 auto-receptors It works by promoting the release...
