Abstract

The invention relates to a children pharmaceutical composition containing ceftriaxone sodium, namely a pharmaceutical combined preparation containing ceftriaxone sodium and a low-sodium carrier infusion solution, and particularly relates to a combined package. The children pharmaceutical composition comprises ceftriaxone sodium for injection and the low-sodium carrier infusion solution. The low-sodium carrier infusion solution contains a glucose and sodium chloride injection (15-200):1, a glucose and sodium chloride potassium chloride injection (15-200):1: (0-1) and the like. Compared with a mixture of ceftriaxone sodium and the low-sodium carrier infusion solution, the children pharmaceutical composition has the advantages that clinical application steps are simplified, clinical risks generated because kidneys of children are not developed to be mature and overmuch sodium in blood cannot be metabolized are reduced, and the clinical application quality and safety performance of children medication are improved.

Description

technical field [0001] The invention relates to a pharmaceutical composition of children's type ceftriaxone sodium and a low-sodium carrier, belonging to the field of medicinal chemistry. Background technique [0002] Ceftriaxone sodium, also known as ceftriaxone, the original research product name: Rocephine, is a new, long-acting, broad-spectrum third-generation semi-synthetic cephalosporin, belonging to β-lactam antibiotics, by inhibiting the synthesis of bacterial cell walls And play a bactericidal effect. It has strong antibacterial activity against most Gram-positive and negative bacteria. The antibacterial spectrum includes Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Haemophilus influenzae, Enterobacter aerogenes, Proteus, Diococcus and Staphylococcus aureus Wait. Clinically, it is mainly used for meningitis, pneumonia, skin and soft tissue infection, peritonitis, urinary system infection, gonorrhea, liver and gallbladder infection, surgical tra...
