| ATC code: | J01CR05 | route: | intravenous |
| n-compartments | 2 |
Piperacillin is a broad-spectrum injectable penicillin-class antibiotic, usually co-administered with tazobactam, a beta-lactamase inhibitor. The combination is used for the treatment of moderate to severe bacterial infections including intra-abdominal, skin, gynecological, and nosocomial respiratory tract infections caused by susceptible organisms. This combination is approved and widely used today.
Pharmacokinetics
Pharmacokinetic parameters reported for piperacillin/tazobactam in healthy adult volunteers (mostly male and female, mean age ~29-35 years) after single intravenous dose.
