Abstract

The invention relates to a compound cefalexin capsule and a preparation method thereof. The compound cefalexin capsule is prepared from the following raw materials in parts by weight: 220-270 parts of cefalexin, 2-20 parts of ambroxol, 25-125 parts of polacrilin potassium, 50-100 parts of chito-oligosaccharide, 5-50 parts of talc and 10-75 parts of starch. The compound cefalexin capsule is reasonable in formula, high in drug dissolution, simple in preparation method without pollution and remarkable in efficacy without adverse reaction.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a compound cephalexin capsule and a preparation method thereof. Background technique [0002] Cephalexin is a broad-spectrum β-lactam antibiotic, the first generation of oral cephalosporins, suitable for Gram-positive and negative cocci including Streptococcus pneumoniae, sensitive Staphylococcus aureus, Neisseria meningitidis, Neisseria gonorrhoeae Some cocci strains. Cefalexin has weak effect on Gram-negative bacilli, and a small number of Escherichia coli may still be sensitive at clinical concentrations. Insensitive pathogens include Streptococcus faecalis, methicillin-resistant Staphylococcus aureus, Haemophilus influenzae, Proteus, Serratia, Enterobacter, and Pseudomonas aeruginosa, etc. drug resistance. The main mechanism of bacterial resistance to cephalexin is the production of β-lactamase. The bactericidal mechanism of cephalexin is t...
