Aztreonam therapy is often accompanied by mild, asymptomatic elevations in serum aminotransferase levels, but it has not been reported to cause clinically apparent liver injury.

Mechanism of action of Aztreonam

Aztreonam (az tree' oh nam) is a monocyclic beta-lactam compound (monobactam) that was originally isolated from Chromobacterium violaceum. It acts by binding to penicillin binding proteins inhibiting cell wall synthesis and decreasing bacterial growth. Aztreonam is active mostly against gram negative organisms and more closely resembles aminoglycosides rather than penicillins.
