Abstract

The invention discloses a beta-cyclodextrin/amoxicillin inclusion complex and a preparation process thereof. The beta-cyclodextrin/amoxicillin inclusion complex is prepared from the following components in percentage by mass: 15-35 percent of amoxicillin, 40-80 percent of beta-cyclodextrin and 0.1-30 percent of aerosil. The preparation process adopts a technology of molecular inclusion complexation by adopting beta-cyclodextrin. The beta-cyclodextrin/amoxicillin inclusion complex has the advantages of low polymer impurity content, hardly deliquescence or casing in storing process, excellent palatability and the like.

Description

technical field [0001] The invention belongs to the technical field of veterinary pharmaceutical preparations, and specifically relates to a β-cyclodextrin / amoxicillin inclusion compound and a preparation process thereof, and the use of the β-cyclodextrin / amoxicillin inclusion compound in the preparation of veterinary drugs. application. Background technique [0002] Amoxicillin, also known as amoxicillin, is a semi-synthetic β-lactam antibiotic, first introduced to the market by BEECHAM in 1972. It has strong bactericidal effect and strong cell penetrating ability, and is easily absorbed by oral administration and injection. , amoxicillin oil for injection and amoxicillin long-acting injection oil have been widely used in the treatment of sensitive bacterial infections in pigs, cattle and poultry. [0003] Due to the β-lactam structure, amoxicillin is prone to intermolecular polymerization and forms sensitizing polymer impurities, making the allergic reaction of its prepa...
