Problems solved by technology

[0003] However, ampicillin sodium and sulbactam sodium are unstable during production and storage, and impurities are easily introduced, such as residual solvents in the production process, degradation of other polymers during storage, etc. These impurities can cause allergies when used clinically. Adverse reactions, which have a serious impact on drug safety, are not conducive to safe drug use in clinical practice

Abstract

The present invention discloses a pharmaceutical composition of ampicillin sodium and sulbactam sodium, wherein a sulbactam sodium is combined with an ampicillin sodium with a specific rotation of +264° to +269°, wherein the ampicillin sodium and the sulbactam sodium have a mass ratio of 2:1. The invention is produced by combining the sulbactam sodium with an ampicillin sodium with a selected specific rotation, thereby improving pharmaceutical stability and user safety of the pharmaceutical composition.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a pharmaceutical composition of ampicillin sodium sulbactam sodium. Background technique [0002] Ampicillin Sodium Sulbactam Sodium is a medicine for injection. The aliases are sultacillin, Youlixin, Shuminxin, Youlixin, Shutaxicillin, Ampicillin-Sulbactam. Its antibacterial mechanism is the same as that of penicillin G, which plays an antibacterial effect by binding to the main penicillin-binding proteins (PBPs) of bacteria and interfering with the synthesis of bacterial cell walls. Its role is characterized by a broad spectrum, not resistant to penicillinase. It is suitable for the treatment of sensitive bacteria, including respiratory tract infections, liver and gallbladder system infections, urinary system infections, and skin and soft tissue infections caused by β-lactamase-producing strains. Treatment of mixed infections of aerobic and anaerobic bacteria, especially abdominal in...
