Problems solved by technology

[0003] However, because cephalexin is a β-lactamase antibiotic, its chemical properties are unstable and easily hydrolyzed, which seriously affects product quality and even affects drug safety.
At present, the marketed preparations are required to be stored in a cool and dark place to ensure the stability of the preparation, which has not fundamentally solved the problem of easy hydrolysis of cephalexin

Abstract

The invention relates to a cefalexin capsule which comprises cefalexin and auxiliary materials. The auxiliary materials comprise filler, a disintegrating agent, a surfactant, a stabilizer, a lubricant and a glidant, wherein the surfactant is one or more of lauryl sodium sulfate, polysorbate-80, poloxamer, polyethylene glycol tricaprylin and polyethylene glycol stearin. The cefalexin capsule disclosed by the invention is short in disintegration time, and drugs dissolve out rapidly.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a cephalexin capsule. Background technique [0002] Cephradine (Cephradine, Velosef), also known as cephalosporin IV, cephalosporin IV, etc., is the first generation of semi-synthetic cephalosporins. ,7R)-3-methyl-7-[(R)-2-amino-2-phenylacetamido]-8-oxo-5-thia-1-azabicyclo[4.2.0]octane-2 -ene-2-carboxylic acid. This product is acid-resistant and can be taken orally, with good absorption and high blood concentration. It is characterized by resistance to β-lactamase. This product has a good antibacterial effect on Neisseria, but Haemophilus influenzae is less sensitive to this product; The product has a certain antibacterial effect on some Escherichia coli, Proteus mirabilis, Salmonella and Shigella. The remaining Enterobacteriaceae, Acinetobacter, Pseudomonas aeruginosa, and Bacteroides fragilis all showed resistance to this product. Fusobacterium and Veillonella are...
