Abstract

The invention discloses an amoxicillin / clavulanate potassium enteric-coated preparation composition and a preparation method thereof. The preparation composition is mainly prepared from amoxicillin, clavulanate potassium and an appropriate auxiliary material. Compared with the common amoxicillin / clavulanate potassium preparation, the amoxicillin / clavulanate potassium enteric-coated preparation provided by the invention has the advantages of less irritation to the stomach so as to reduce adverse reaction, and the like. The amoxicillin / clavulanate potassium enteric-coated preparation composition is particularly suitable for patients with stomach upset. The invention provides a novel formulation which has higher safety and better curative effect compared with those of the conventional amoxicillin / clavulanate potassium related preparations; and the preparation process has the advantages of high quality controllability and stability.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to an amoxicillin / potassium clavulanate enteric-coated preparation composition and a preparation method thereof. Background technique [0002] Amoxicillin / potassium clavulanate, their chemical names are: (2S, 5R, 6R)-3,3-dimethyl-6-[(R)-(-)-2-amino-2-(4 -Hydroxyphenyl)acetamido]-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid trihydrate and (Z)-(2S,5R)-3 Potassium -(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo[3.2.0]heptane-2-carboxylate. [0003] Amoxicillin / potassium clavulanate compound preparation is composed of amoxicillin and potassium clavulanate. It is a broad-spectrum enzyme-resistant and highly effective first-line anti-infective drug for severe infections commonly seen in clinical practice. Among them, amoxicillin is a broad-spectrum penicillin β-lactam semi-synthetic antibiotic, the mechanism of action is to inhibit the synthesis of bacterial cell walls, has ...
