A semisynthetic parenteral cephalosporin. It exhibits modest activity compared to other antipseudomonal cephalosporins. Like cefoperazone, it is susceptible to many enterobacterial β-lactamases. In volunteers receiving 0.1–1 g intramuscularly, mean peak plasma concentrations reached 15–20 and 35–40 mg/L, respectively. There was no accumulation when the dose was repeated every 8 h for 7 days. No metabolites have been detected. The plasma elimination half-life is 1.8– 2.1 h. The principal route of elimination is renal, 70–80% being recovered unchanged in the urine.
Significant pain at the site of infection has been a prominent adverse event. It is no longer widely available.
