Problems solved by technology

[0005] Chinese patent CN101647779A discloses a new amoxicillin sodium clavulanate potassium compound powder for injection and its preparation technology. Although the ratio of amoxicillin sodium / clavulanate potassium has been changed and the preparation process has been improved, it has no effect on the activity The ingredients have not taken any protective measures, the stability is poor, and the clarity after reconstitution is poor
[0008] The prior art does not disclose microsphere preparations of amoxicillin sodium and clavulanate potassium, and the art still needs an excellent pharmaceutical composition of amoxicillin sodium and clavulanate potassium, which has excellent sustained-release properties and stability, and the present invention Amoxicillin sodium and clavulanate potassium microspheres were prepared by using microsphere technology, and amoxicillin sodium and clavulanate potassium microsphere injections with excellent sustained-release characteristics and stability were provided

Abstract

The invention discloses an amoxicillin sodium potassium clavulanate composition microballoon injection, which is characterized by comprising the following components in parts by weight: 5 parts of amoxicillin sodium, 1 part of potassium clavulanate, 4-6 parts of gelatin, 4-6 parts of Arabic gum, 3-6 parts of disodium hydrogen phosphate, 2-4 parts of trehalose and 1-3 parts of glycerol. Compared with the prior art, the amoxicillin sodium potassium clavulanate composition microballoon injection prepared by the invention has good stability, high entrapment rate, good process repeatability, even particle distribution, good injectable property and good slow release character, and is suitable for industrialization production.

Description

technical field [0001] The invention relates to a microsphere injection of a pharmaceutical composition, in particular to a microsphere injection of amoxicillin sodium clavulanate potassium pharmaceutical composition, and belongs to the field of pharmaceutical preparations. Background technique [0002] Amoxicillin is a broad-spectrum penicillin antibiotic, and clavulanate potassium itself has only weak antibacterial activity, but has a strong broad-spectrum β-lactamase inhibitory effect. The combination of the two can protect amoxicillin from β-lactamase hydrolysis. The antibacterial spectrum of this product is the same as that of amoxicillin, and it has been expanded. It has a good effect on enzyme-producing Staphylococcus aureus, Staphylococcus epidermidis, coagulase-negative staphylococcus and enterococci, and has good effects on certain β-lactamase-producing Enterobacteriaceae, Haemophilus influenzae, and Moraxella catarrhalis , Bacteroides fragilis, etc. also have goo...
