Abstract

The invention discloses an amoxicillin particle and a preparation process thereof. In the preparation process of the amoxicillin particle, a low-moisture volatile adhesive solution and a cold drying technology are adopted. The invention has the advantages that the stability of the amoxicillin particle is enhanced; and within the 36-month valid period of the amoxicillin particle, the safety and validness of the amoxicillin particle in clinical use are ensured, and no penicillin anaphylaxis is generated.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a stable amoxicillin granule preparation and a preparation process thereof. Background technique [0002] Amoxicillin, also known as amoxicillin, is a semi-synthetic broad-spectrum penicillin. Enterococcus, Salmonella, Salmonella typhi and Proteus all have antibacterial effects. Because of its strong acid resistance, broad antibacterial spectrum and definite curative effect, it is widely used in clinic. [0003] The chemical name of amoxicillin is: 6-[2-amino-2-(4-hydroxyphenyl)acetamido]-3,3-dimethyl-7-oxo-4-thia-1-aza Bicyclo[3.2.0]heptane-2-carboxylic acid trihydrate, 6-[2-Amino-2-(4-hydroxyphenyl)-acetyl]amino-3, 3-dimethyl-7-oxo-4-thia-1 -azabicyclo[3.2.0]heptane-2-carboxylic acidtrihydrate, whose structural formula is: [0004] [0005] Molecular formula: C16H19N3O5S 3H2O Molecular weight: 419.46 [0006] Due to the instability of the...
