Abstract

The invention provides a suspension powder-injection preparation of an amoxicillin sodium, and flucloxacillin sodium medicinal composition and new application thereof, and particularly discloses a suspension powder-injection preparation of an amoxicillin sodium and flucloxacillin sodium medicinal composition and a method for preparing the same. The suspension powder-injection preparation comprises the following components in part by weight: 1 part of amoxicillin sodium, 1 part of flucloxacillin sodium, 2 to 18 parts of emulsifier, 0.5 to 12 parts of auxiliary emulsifier and 3 to 20 parts of freeze-dry supporting agent. Furthermore, the invention relates to the application of the suspension powder-injection preparation in the preparation of medicaments for treating pelvic inflammatory diseases.

Description

technical field [0001] The present invention relates to a new dosage form of amoxicillin sodium flucloxacillin sodium pharmaceutical composition, in particular to amoxicillin sodium flucloxacillin sodium pharmaceutical composition suspension powder injection and its preparation method, and further relates to its preparation and treatment of pelvic infection new applications in medicine. Background technique [0002] Pelvic inflammatory disease mostly occurs in women, and the incidence rate has remained high in recent years and has an increasing trend. The main high-risk factors include: infection after intrauterine surgery; lower genital tract infection, mainly sexually transmitted diseases of the lower genital tract; direct spread of clinical organ inflammation. The common pathogens that cause the disease are: aerobic bacteria, anaerobic bacteria, sexually transmitted pathogens, viral infections, etc. Clinically, due to the acute onset and serious condition, it is often t...
