Abstract

The invention discloses a preparation process for compound recipe amoxicillin oil suspensoid injection. The preparation process comprises the following steps: (1) heating, sterilizing and cooling down neutual soybean oil, adding aluminum stearate into the soybean oil to prepare gel, heating the gel, diluting the gel through the filtrated and sterilized soybean oil, and filtrating the gel for standby; and (2) taking amoxicillin and clavulanic acid according to a recipe, mixing the amoxicillin and the clavulanic acid with the factice, grinding the mixture in a mortar, adding lecithin into the mixture while grinding till the mixture is ground evenly, adding the factice and the like into the mixture, adding benzyl alcohol, span and vitamin E into a graduated cylinder, and stirring the mixture, adding the factice and the like into the graduated cylinder, packaging and sealing the mixture and obtaining the compound recipe amoxicillin oil suspensoid injection. The compound recipe amoxicillin oil suspensoid injection has the advantages that the compound recipe amoxicillin oil suspensoid injection has a long-acting slow-releasing action, and antibacterial activity against bacteria capable of resisting single recipe amoxicillin, ampicillin, ceftiofur, and the like, that is, the compound recipe amoxicillin oil suspensoid injection can effectively treat bacterial infection capable of generating ESBLs. The preparation process is simple and convenient.

Description

technical field [0001] The invention relates to a medicine, in particular to a preparation process of compound amoxicillin oil suspension injection. Background technique [0002] Amoxicillin is a broad-spectrum semi-synthetic penicillin commonly used in veterinary clinics. It can be used to treat Escherichia coli, Salmonella, Pasteurella, Proteus and other digestive tract, respiratory tract and urinary tract infections. With its wide application, strains resistant to amoxicillin continue to emerge. The main mechanism of drug resistance is the production of β-lactamase, which hydrolyzes the β-lactamase ring of amoxicillin to make the latter lose its antibacterial activity. Clavulanic acid and sulbactam sodium are irreversible competitive β-lactamase inhibitors, which can inhibit the β-lactamase produced by bacteria, restore the sensitivity of bacteria to amoxicillin, and improve the antibacterial activity of amoxicillin . [0003] Amoxicillin-clavulanic acid preparations ha...
