Overview

Ceftazidime Pentahydrate is a third generation cephalosporin antibiotic. Cephalosporins are composed of 7-aminocephalosporanic acids and are of different sizes depending on their side chain substituents. Studies show that Ceftazidime Pentahydrate has greater activity against|Pseudomonas aeruginosa|than it does against gram-positive cocci.
