Abstract

The invention discloses a suspension powder injection with a cefoperazone sodium and tazobactam sodium pharmaceutical composition as an active ingredient, and comprises the following components: 4 parts of the cefoperazone sodium, 1 part of the tazobactam sodium, 5-30 parts of an emulsifier, 1-15 parts of an auxiliary emulsifier and 1-40 parts of a freeze-drying support agent. The invention further discloses an application thereof in preparing medicines for treating cystitis.

Description

technical field [0001] The invention relates to cefoperazone sodium tazobactam sodium pharmaceutical composition suspension powder injection, and further relates to its new application in the preparation of medicines for treating cystitis. Background technique [0002] Cystitis is a common and frequently-occurring infectious disease in clinical practice. It is intractable and protracted. It takes a long time to treat and has a high recurrence rate. There are two clinical manifestations of cystitis, acute and chronic.
