Abstract

The invention belongs to the technical field of medicine, and discloses a medicinal-composition suspension powder injection taking mezlocillin sodium and sulbactam sodium as active components. The injection comprises 4 parts of mezlocillin sodium, 1 part of sulbactam sodium, 5 to 20 parts of Tween 80, 1 to 10 parts of cholesterol, 0.5 to 15 parts of deoxysodium cholate, and 2 to 30 parts of frozen-dried supporting agent. The invention further discloses novel application of the injection in the preparation of medicaments for preventing postoperative infection of appendicitis.

Description

technical field [0001] The invention relates to a suspension powder injection of the mezlocillin sodium sulbactam sodium pharmaceutical composition and a preparation method thereof, and further relates to its new application in the preparation of a drug for preventing postoperative infection of appendicitis. Background technique [0002] Acute suppurative appendicitis is the most common cause of surgical emergency, and surgical resection of the appendix is ​​the treatment of choice. Suppurative appendicitis is usually a mixed infection of Gram-negative bacilli and anaerobic bacteria, and the incidence of secondary infection after surgery is high. If antibiotics are not used during the perioperative period, the postoperative incision infection rate of suppurative or gangrenous appendicitis is 33% to 34.6%. [0003] Mezlocillin (Mezlocilline, Bay1353) belongs to the ureide penicillin, as the most valuable ureide penicillin widely used at home and abroad, it is effective again...
