Problems solved by technology

Carbapenems are the drug of choice for the treatment of severe Acinetobacter baumannii infections, but carbapenem-multidrug-resistant strains have emerged around the world in recent years, with worrying multi-drug resistance emerging from Spain to Norway The "invasion" phenomenon of Acinetobacter baumannii is prevalent among traumatized soldiers of the U.S. and British troops stationed in Afghanistan and Iraq, causing serious public health problems. Acinetobacter baumannii brought back by the U.S. military in Iraq is prevalent in the United States

Abstract

The invention provides a combined medicine and specifically provides a combined medicine of imipenem / cilastatin sodium and sulbactam sodium for treating infectious diseases caused by acinetobacter baumanii. The combined medicine of imipenem / cilastatin sodium and sulbactam sodium has a synergistic effect and accumulated antibacterial action on infectious diseases caused by acinetobacter baumanii, especially a good synergistic effect and accumulated antibacterial action on multidrug resistant acinetobacter baumanii stains, and can be used for curing clinical infection caused by multidrug resistant acinetobacter baumanii in clinical practice.

Description

technical field [0001] The invention provides a combination medicine, in particular, a combination medicine of imipenem cilastatin sodium / sulbactam sodium for treating infectious diseases caused by Acinetobacter baumannii. It belongs to the field of medical technology. Background technique [0002] Carbapenem antibiotics are a class of antibiotics with the broadest antibacterial spectrum and strong antibacterial activity so far. In the past 20 years, imipenem and cilastatin sodium among carbapenems have been used as compound preparations. Its components are imipenem 500mg and cilastatin sodium (calculated as C16H25N2O5S) 500mg, which are key drugs for the treatment of severe infections, especially in the treatment of severe infections of the respiratory tract, which have irreplaceable curative effects and have saved the lives of countless patients , but with the widespread use of carbapenems, the resistance rate of Acinetobacter baumannii to carbapenems has increased year b...
