Ceftazidime pentahydrateProduct ingredient for Ceftazidime

Name
Ceftazidime pentahydrate
Drug Entry
Ceftazidime

Bacteria possess a cell wall comprising a glycopeptide polymer commonly known as peptidoglycan, which is synthesized and remodelled through the action of a family of enzymes known as "penicillin-binding proteins" (PBPs).1 β-lactam antibiotics, including cephalosporins, are PBP inhibitors that, through inhibition of essential PBPs, result in impaired cell wall homeostasis, loss of cell integrity, and ultimately bacterial cell death.1,2,3 Ceftazidime is a third-generation cephalosporin with broad-spectrum antibacterial activity, including against some treatment-resistant bacteria such as Pseudomonas aeruginosa.12

Ceftazidime was approved by the FDA on July 19, 1985, and is currently available either alone or in combination with the non-β-lactam β-lactamase inhibitor avibactam to treat a variety of bacterial infections.12,13
