Abstract

The invention discloses a novel cefazolin sodium compound with lower moisture absorption, better storage stability and the like, composition of the compound and an application of the compound in preparation of drugs for treating or preventing respiratory tract infection of human or animals due to gram positive or negative bacterial sensitive bacteria, endocarditis, peritonitis, pyelonephritis, urinary tract infection, septicemia and infection of bone, joints, skin and soft tissue.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to provide a novel compound with better stability of the antibacterial drug cefazolin sodium, a pharmaceutical composition thereof, a preparation method and application thereof. Background technique [0002] The antibacterial spectrum of cefazolin sodium is similar to that of cephalexin. It is effective against Staphylococcus (including enzyme-producing strains), Streptococcus (except Enterococcus), Streptococcus pneumoniae, Escherichia coli, Proteus mirabilis, Klebsiella, Haemophilus influenzae and producing Enterobacter aerogenes have antibacterial effect. It is characterized by a strong effect on Gram-negative bacteria and weak resistance to Staphylococcus β-lactamase. Usually used for injection. After intramuscular injection of 1g, the blood concentration in 1 hour is 64μg / ml; in intravenous injection of 1g, the blood concentration in 30 minutes is 106μg / ml. The half-life is...
