PIPERACILLIN-TAZOBACTAM

OVERVIEW
Piperacillin-Tazobactam

 

Introduction

Piperacillin is an extended-spectrum ureidopenicillin which, when combined with the beta-lactamase inhibitor tazobactam, is used to treat moderate-to-severe infectious due to susceptible organisms including lactamase producing penicillin-resistant bacteria.  Piperacillin-tazobactam has been linked with idiosyncratic liver injury, but only rarely and as isolated case reports.

 

Background

Piperacillin-tazobactam is the combination of a fourth generation, extended-spectrum penicillin and a beta-lactamase inhibitor that is used for moderate-to-severe infections caused by susceptible agents, such as (but not limited to) Escherichia coli, many Bacteroides and Klebsiella species, Staphylococcus aureus, and Haemophilus  influenzae.  The combination of piperacillin with tazobactam provides broad activity against beta-lactamase producing penicillin-resistant bacterial species.  This combination was approved for use in the United States in 1985 and is generally reserved for severe infections requiring parenteral therapy.  Piperacillin-tazobactam is available in parenteral form for intravenous use in generic forms and under the trade name Zosyn.  Recommended doses are 3 to 4.5 grams of piperacillin with 0.375 to 0.5 grams of tazobactam every 6 to 8 hours for 7 to 14 days.  Common side effects include headache, dizziness, nausea, diarrhea, constipation, skin rash and hypersensitivity reactions.

 

Hepatotoxicity

In large clinical trials, ALT elevations were reported in 6% to 15% and bilirubin elevations in 3 to 5% of patients receiving piperacillin-tazobactam, with considerably lower rates in patients receiving comparator antibiotics (such as imipenim-cilastatin) and lower rates reported with piperacillin alone.  These abnormalities were reported to resolve quickly with stopping therapy.  Rare instances of idiosyncratic liver injury have been reported in persons receiving the piperacillin without tazobactam.  This combination does not appear to increase the risk of cholestatic hepatitis that might be caused by piperacillin or other penicillins and is not associated with the common delayed cholestatic hepatitis that it typical of clavulanate combinations with penicillins (amoxicillin or ticarcillin).

 

Mechanism of Injury

The cause of the liver injury associated with piperacillin use is probably hypersensitivity or allergy.  Cases of reoccurrence on reexposure have been reported.

 

Outcome and Management

In the few cases that have been described, patients have recovered promptly.  Patients with piperacillin induced hepatitis should avoid reexposure to other penicillins and should take cephalosporins with caution.
