Abstract

The invention discloses a tablet containing paroxetine and a preparation method thereof. The tablet is composed of paroxetine hydrochloride and auxiliary materials accepted in pharmacy and prepared in a wet granulation process, thereby not affecting tablet manufacturing modes and guaranteeing quality and stability of tablets. The tablet is simple in preparation method, wide in application scope, convenient to transport and store and suitable for scale production. The preparation method is convenient to operate.

Description

technical field [0001] The invention relates to a tablet containing paroxetine and a preparation method thereof. The tablet is prepared by a wet granulation process, which does not affect the preparation form and ensures the quality and stability of the preparation. The preparation method is simple and the operation is convenient , has a wide range of applications, is convenient for transportation and storage, and is suitable for large-scale production. Background technique [0002] According to the classification of biopharmaceuticals, paroxetine belongs to the class of drugs with high solubility and high permeability. Its chemical structure is different from piperidine compounds of tricyclics, tetracyclics and other existing antidepressants, and is suitable for oral administration. [0003] Temperature and humidity have a great influence on paroxetine, and it often appears pink, and its hydrochloride form is relatively stable, but if it encounters a substance with strong ...
