Ceftazidime Hydrochloride is a non-toxic hydrochloride salt derivative of Ceftazidime, a broad-spectrum, third-generation, β-lactam cephalosporin that interferes with bacterial cell wall synthesis. Patented in 1979 by Glaxo Group, it came into commercial use in 1984. It is derived from cephaloridine. Interestingly, it can generate degradation products in aqueous solutions that are actually inhibitory to HIV-1 cell lines in vitro. Ceftazidime Hydrochloride is sparingly soluble in aqueous solution. Organic solvents are commonly used to facilitate dissolution.

Background
Like β-lactams, cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to cephalosporins is commonly due to cells containing plasmid encoded β-lactamases, however, ceftazidime is stable in the presence of β-lactamases.
