DOSAGE AND ADMINISTRATION
Piperacillin and tazobactam for injection is indicated only for the specified conditions listed above. Infections caused by piperacillin-susceptible organisms, for which piperacillin has been shown to be effective, are also amenable to piperacillin and tazobactam for injection treatment due to its piperacillin content. The tazobactam component of this combination product does not decrease the activity of the piperacillin component against piperacillin-susceptible organisms. Therefore, the treatment of mixed infections caused by piperacillin-susceptible organisms and piperacillin-resistant, ß-lactamase producing organisms susceptible to piperacillin and tazobactam for injection should not require the addition of another antibiotic (see
DOSAGE AND ADMINISTRATION
Piperacillin and tazobactam for injection is useful as presumptive therapy in the indicated conditions prior to the identification of causative organisms because of its broad spectrum of bactericidal activity against gram-positive and gram-negative aerobic and anaerobic organisms.
Appropriate cultures should usually be performed before initiating antimicrobial treatment in order to isolate and identify the organisms causing infection and to determine their susceptibility to piperacillin and tazobactam for injection. Antimicrobial therapy should be adjusted, if appropriate, once the results of culture(s) and antimicrobial susceptibility testing are known.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of piperacillin and tazobactam for injection and other antibacterial drugs, piperacillin and tazobactam for injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Clinical Trials Related to Piperacillin and Tazobactam (Piperacillin / Tazobactam)
Safety and Pharmacokinetics of Piperacillin-tazobactam Extended Infusion in Infants and Children (PIP-TAZO) [Not yet recruiting]
Severe infection is one of the main causes of disease in hospitalized children and can be
deadly. With the lack of novel antibiotics approved in children and the emergence of drug
resistant bacteria, there is a critical need to optimize dosing of existing antibiotics.
Piperacillin-tazobactam is an antibiotic frequently used for treatment of severe infection
in children in Canadian hospitals. To optimize this antibiotic's efficacy despite the rise
of antibiotic resistance, alternative dosing strategy is commonly used in adults, which
consists of prolonging the time during which the drug is infused (4 hours instead of 30
min). Children clear piperacillin-tazobactam from their bodies at a slower rate than adults,
consequently extended-infusion strategy cannot be directly extrapolated from adult to
children. We believe that younger children need piperacillin-tazobactam infusions that are
shorter compared to adults to achieve appropriate concentrations.
Piperacillin-Tazobactam Continuous Versus Intermittent Infusion for Pseudomonas Aeruginosa [Completed]
The main objective is to verify that the administration of piperacillin / tazobactam
administered by continuous infusion to treat complicated infections or with known or
suspected nosocomial isolation of Pseudomonas aeruginosa is superior in efficacy to a 30%
higher dose administered in conventional short infusion.
The secondary objectives were compared between the following variables:
- Microbiological response at 3 days of starting treatment
- Time to microbiological cure
- Clinical response at 3 days of starting treatment
- Time to achieve defervescence
- To examine the relationship between pharmacokinetic variables and parameters of
efficacy and safety
- To test the hypothesis that continuous infusion maintains adequate plasma drug levels
compared with levels achieved with intermittent administration.
- Cost-effectiveness analysis
- Occurrence of adverse effects
To this end, we designed a multicenter, randomized, controlled, double blind, comparing both
forms of administration in patients with complicated or nosocomial infection with or without
isolation of Pseudomonas aeruginosa.
Patients who are candidates for inclusion are classified according to APACHE II and to have
or not isolation of Pseudomonas aeruginosa. Subsequently be randomized to receive
piperacillin-tazobactam by continuous infusion or short. Primary endpoint was measured as
the ultimate effectiveness of treatment and other variables such as high efficiency, safety,
pharmacokinetic and pharmacoeconomic.
PK/PD of High Dose Pip/Tazo in Obese Patients [Recruiting]
Worldwide rates of obesity have doubled in the last 30 years, and obesity has been
associated as a risk factor for hospital-acquired infections and increased occurrence of
death in critically-ill patients. Piperacillin/tazobactam is a commonly prescribed
antibiotic for critically ill patients with an infection, however, limited information
exists for dosing this drug in obese patients. In these limited reports, standard doses of
piperacillin/tazobactam given to the small number of obese patients resulted in lower blood
concentrations, which could lead to inadequate killing of bacteria. The purpose of this
study is to compare blood concentrations from standard piperacillin/tazobactam dosing
compared to higher dosing regimens in obese patients. This study will also include
information on the safety and tolerability of the higher dose regimens. The study
investigators believe that the higher dosing regimen will produce adequate blood levels in
obese patients and will not add any more risk of harm to obese patients receiving this
Pharmacokinetics of Piperacillin/Tazobactam in Patients Treated by Continuous Renal Replacement Therapy [Completed]
The pharmacokinetics of piperacillin/tazobactam will be evaluated in twenty septic patients
with renal failure undergoing continuous veno-venous hemodiafiltration.
Continuous Infusion Piperacillin-tazobactam for the Treatment of Cystic Fibrosis [Terminated]
Cystic fibrosis is an inherited disorder leading to chronic pulmonary inflammation and
infection. A majority of people with cystic fibrosis have large quantities of bacteria
residing in their lungs. One of the most common and harmful bacteria is called Pseudomonas
Patients with cystic fibrosis require frequent therapy with intravenous (I. V.) antibiotics
to treat lung infections thought to be caused by Pseudomonas aeruginosa. One of the
antibiotics frequently used to treat this bacteria is piperacillin-tazobactam.
Piperacillin-tazobactam is thought to be the most effective when there is a constant level
of drug in the body. The standard way to administer piperacillin-tazobactam is to give
several grams 4 times each day as a 30 minute infusion. An alternative way to give
piperacillin-tazobactam is by a continuous infusion; a continuous infusion will make it more
likely that drug will remain at a constant level in the body. The objective of this study is
to determine if administering piperacillin-tazobactam as a continuous infusion is more
effective at treating people having a pulmonary exacerbation of cystic fibrosis than a
standard 30 minute infusion, 4 times a day.
