Abstract

The invention discloses a suspension powder injection of a piperacillin sodium and tazobactam sodium pharmaceutical composition, and further discloses an application thereof to preparing medicines for treating lung abscess.

Description

technical field [0001] The invention relates to piperacillin sodium-tazobactam sodium pharmaceutical composition suspension powder injection and its new therapeutic application. Background technique [0002] Lung abscess refers to the suppurative lesion of the lungs caused by various pathogenic bacteria infection. The early stage is purulent inflammation, followed by tissue necrosis and abscess. Since the use of antibiotics, the incidence of the disease has decreased significantly, but in recent years, due to the abuse of antibiotics, drug-resistant strains have increased, and because the abscess cavity of the lung abscess is surrounded by a layer of uneven thickness and fibrous tissue, general antibiotics are not suitable. Through this wall into the abscess cavity, conventional therapy is not good, resulting in poor curative effect and slow recovery of the disease course. In severe cases, pulmonary abscess drainage or even surgical lung abscess resection is required, which ...
