Mechanism of Action

Aztreonam exhibits bactericidal action by inhibiting bacterial cell wall synthesis due to its high affinity for penicillin-binding protein 3 (PBP-3) of gram-negative bacteria. It is highly resistant to hydrolysis by β-lactamases. It is active against Enterobacteriaceae spp, E. coli, Klebsiella, Proteus, Providencia, Salmonella, Serratia, Shigella and Yersinia spp.. Absorption: Absorbed poorly from the GI tract (oral). Distribution: Body tissues and fluids (wide), bile, CSF (especially in the presence of meningitis), crosses the placenta and enters breast milk. Protein-binding: 56%. Metabolism: Minimal metabolism; SQ-26992 (primary metabolite, inactive). Excretion: Via urine by renal tubular secretion and glomerular filtration (60-70% as unchanged), via faeces (small amounts of unchanged drug and metabolites); 1.7 hr (elimination half-life). Removed by dialysis and peritoneal dialysis (lesser extent).

Special Precautions

Hypersensitivity to other β-lactams; renal and hepatic impairment; pregnancy.
