What is Cefquinome sulfate?

Description

Cefquinome sulfate is a veterinary, parenteral, fourth-generation cephalosporin belonging to the class of aminothiazolyl compounds. They have high cell permeability and high stability to beta-lactamases. They have broad-spectrum antimicrobial activity against Gram-positive and Gram-negative bacteria (e.g. Pseudomonas aeruginosa and Enterobacteriaceae).

Chemical properties

Cefquinome sulfate is Off-White Solid

The Uses of Cefquinome sulfate

An antibacterial used in veterinary medicine. Used in the treatment of infections caused by pathogens such as S. aureus, E. coli, Streptococcus, P. multocida and A. pleuropneumoniae. Also used to treat mastitis in dairy cows.
