Problems solved by technology

[0005] There are few patents related to the prescription composition and preparation process of Bepotastine Bepotastine Tablets. The original patent JP2007003909998 describes the composition and preparation method of Bepotastine Bepotastine Tablets. The preparation process is a melt granulation wet granulator , for melt granulation. This patent uses special equipment. There is no mature production line for this special equipment in China, and it is necessary to build a special production line at a high cost.
In addition, the relevant domestic preparation patents are CN201610683980.9, which describes the composition and preparation method of bepotastine bepotastine tablets. The preparation process adopts oven heating, melting and granulation, which has many problems: the uneven distribution of polyethylene glycol 6000 The difference is large, and it is easy to produce huge hard lumps, which is not conducive to granulation, and the operation is complicated, which is not conducive to industrial production

Abstract

The invention belongs to the technical field of medicines, and relates to a preparation method of a bepotastine bepotastine pharmaceutical composition, which adopts conventional wet granulation equipment for wet granulation, and the ratio of polyethylene glycol 6000 to water is 2 in mass ratio :1-20:1 mixed and heated, added to the material containing bepotastine bepotastine and excipients for granulation, and made into a bepotastine bepotastine pharmaceutical composition. Compared with the original preparation, the preparation method of the present invention has lower requirements on equipment and technology, and has a mature production line in China, which is suitable for industrial production. The prepared bepotastine bepotastine tablet has good stability, and its dissolution curve is comparable to that of the reference The formulations are consistent.

Description

technical field [0001] The invention relates to a method for preparing a pharmaceutical composition of bepotastine besilate, and the pharmaceutical composition particularly relates to a tablet of bepotastine besilate. The preparation process of this method is simple to operate, adopts conventional wet granulator to carry out wet granulation, has lower requirement than reference preparation equipment (melt wet granulator), has mature production line in China, is suitable for industrialized production, and the prepared besulphate The stastatin tablet has good stability, and its dissolution profile is consistent with that of the reference preparation (bepotastine besilate tablet, trade name Tanliang). Background technique [0002] Allergic rhinitis is allergic rhinitis, which refers to the release of mediators (mainly histamine) mediated by IgE after atopic individuals are exposed to allergens, and a variety of immune active cells and cytokines are involved. Noninfectious infl...
