Administer
ation
Tazo-Pip Avenir 4.5g may be given by slow intravenous
injection (over at least three to five minutes) or by slow
intravenous infusion (over 20-30 minutes).
For reconstitution instructions, see section 6.6.
The treatment of mixed infections caused by piperacillin
susceptible organisms and beta-lactamase producing organisms
susceptible to piperacillin/tazobactam generally do not require
the addition of another antibiotic.
In patients with nosocomial pneumonia and infections in
neutropenic patients Tazo-Pip Avenir can be used with an aminoglycoside.
If the use of an aminoglycoside is needed with piperacillin/tazobactam,
both Tazo-Pip Avenir 4.5g and the aminoglycoside must be used in
completely therapeutic doses.
Neutropenic patients with signs of infection (e.g. fever) should
receive immediate empirical antibiotic therapy before laboratory
results are available.
Adults and Children Over 12 Years, Each with Normal
Renal Function
The usual dosage for adults and children over 12 years is Tazo-Pip
Avenir 4.5 g given every eight hours.
Posology
The dose and frequency of Tazo-Pip Avenir 4.5g
depends
on the severity and localisation of the infection and
expected pathogens.
Adult and adolescent patients
Infections
The usual dose is 4 g piperacillin / 0.5 g tazobactam given
every 8 hours.
For nosocomial pneumonia and bacterial infections in neutropenic
patients, the recommended dose is 4 g piperacillin / 0.5 g
tazobactam administered every 6 hours. This regimen may also be
applicable to treat patients with other indicated infections when
particularly severe.
The following table summarises the
treatment frequency and the
recommended dose for adult and
adolescent patients by indication or
condition:
The total daily dose of piperacillin/tazobactam depends on
the severity and localisation of the infection and can vary from piperacillin/
tazobactam 2000/250 mg to piperacillin/tazobactam 4000/500 mg
administered every six or eight hours.
In neutropenia the recommended dose is piperacillin/tazobactam
4000/500mg given every six hours in combination with an
aminoglycoside.
Elderly with Normal Renal Function
Tazo-Pip Avenir may be used at the same dose levels as adults
except in cases of renal impairment (see below):
Renal Insufficiency in Adults, the Elderly and Children
(over 40kg) Receiving the Adult Dose
In patients with renal insufficiency, the intravenous dose should be
adjusted to the degree of actual renal impairment.
The suggested daily doses are as follows:

For patients on haemodialysis, the maximum daily dose is
piperacillin/tazobactam 8/1 g. In addition, because haemodialysis
removes 30%-50% of piperacillin in four hours, one additional
dose of piperacillin/tazobactam 2000/250 mg should be
administered following each dialysis period.
For patients with renal failure and hepatic insufficiency,
measurement of serum levels of piperacillin/tazobactam
will provide additional guidance for adjusting dosage.
Children Aged 2-12 Years with Normal Renal Function
Tazo-Pip Avenir is only recommended for the treatment
of children with neutropenia.
Neutropenia
For children weighing less than 40kg the dose should be
adjusted to 90 mg/kg (piperacillin/tazobactam 80/10 mg)
administered every six hours, in combination with an

For patients on haemodialysis, one additional dose of
piperacillin / tazobactam 2 g / 0.25 g should be
administered following each dialysis period, because
haemodialysis removes 30%-50% of piperacillin in 4 hours
. the maximum dose is 2.25 g every twelve hours
for all indications other than nosocomial
pneumonia and 2.25 g every eight hours for
nosocomial pneumonia. Since hemodialysis
removes 30% to 40% of the administered dose,
an additional dose of 0.75 g piperacillin-Tazobactam
should be administered following each dialysis
period on hemodialysis days.
Hepatic impairment
No dose adjustment is necessary (see section 5.2).

Special
Warnings and
Special
Precautions
for Use
Before initiating therapy with Tazo-Pip Avenir 4.5g, careful inquiry
should be made concerning previous hypersensitivity reactions to
penicillins.cephalosporins, and other allergens.
Serious and occasionally fatal hypersensitivity (anaphylactic shock])
reactions have been reported in patients receiving therapy with penicillins
including piperacillin/tazobactam. These reactions are more likely
to occur in persons with a history of sensitivity to multiple allergens.
Patients may experience neuromuscular excitability or convulsions if
higher than recommended doses are given intravenously
The selection of piperacillin / tazobactam to treat an
individual patient should take into account the
appropriateness of using a broad-spectrum semi-synthetic
penicillin based on factors such as the severity of the
infection and the prevalence of resistance to other suitable
antibacterial agents.
Before initiating therapy with Tazo-Pip Avenir 4.5g,
careful inquiry should be made concerning previous
hypersensitivity reactions to penicillins, other beta lactam
agents (e.g.cephalosporins,monobactam or carbapenem)
and other allergens.
Serious and occasionally fatal hypersensitivity sitivity
(anaphylactic/anaphylactoid [including shock]) reactions
have been reported in patients receiving therapy with
penicillins including piperacillin/tazobactam. These
reactions are more likely to occur in persons with a
history of sensitivity to multiple allergens.
Serious skin reactions, such as Stevens-Johnson syndrome
and toxic epidermal necrolysis, have been reported in
patients receiving piperacillin/tazobactam (see section 4.8).
If patients develop a skin rash they should be monitored
closely and piperacillin/tazobactam discontinued if lesions
progress
Patients may experience neuromuscular excitability or
convulsions if higher than recommended doses are given
intravenously.
As with treatment with other penicillins, neurological
complications in the form of convulsions may occur when
high doses are administered, especially in patients with
impaired renal function.

4. CLINICAL PARTICULARS
Go to top of the page
4.1 Therapeutic indications
Antibiotic for the treatment of moderate to severe systemic and/or local bacterial
infections caused by susceptible organisms.
Piperacillin/Tazobactam in combination with an aminoglycoside, is indicated for the
treatment of suspected bacterial infections in neutropenic adults and children.
Appendicitis complicated by rupture with peritonitis and/or abscess formation in children
aged 2-12 years.
This indication of the medicine has not been evaluated in pediatric patients under two
years.
Appropriate culture and susceptibility tests should be performed before treatment in order
to identify organisms causing infections and to determine their susceptibilities to
piperacillin/tazobactam. Because of its broad spectrum of activity against Gram-positive
and Gram-negative aerobic and anaerobic organisms, piperacillin/tazobactam is
particularly useful in the treatment of mixed infections and in presumptive therapy prior to
the availability of the results of sensitivity tests.
Therapy with piperacillin/tazobactam may, however, be initiated before results of such
test are known. Modification of the treatment may be required once these results become
available or if there is no clinical response.
In serious infections presumptive therapy with piperacillin/tazobactam may be initiated
before susceptibility test results are available.
piperacillin/tazobactam acts synergistically with aminoglycosides against certain strains of
Pseudomonas aeruginosa. Combined therapy has been successful, especially in patients
with impaired host defenses. Both drugs should be used in full therapeutic doses. As
soon as results of culture and susceptibility test become available, antimicrobial therapy
should be adjusted.

4.4 Special warnings and precautions for use
Warnings
The selection of piperacillin / tazobactam to treat an individual patient should take into
account the appropriateness of using a broad-spectrum semi-synthetic penicillin based on
factors such as the severity of the infection and the prevalence of resistance to other
suitable antibacterial agents.
Before initiating therapy with Tazo-Pip Avenir 4.5g, careful inquiry should be made
concerning previous hypersensitivity reactions to penicillins, other beta lactam agents
(e.g.cephalosporins,monobactam or carbapenem) and other allergens.
Serious and occasionally fatal hypersensitivity (anaphylactic/anaphylactoid [including
shock]) reactions have been reported in patients receiving therapy with penicillins
including piperacillin/tazobactam. These reactions are more likely to occur in persons with
a history of sensitivity to multiple allergens.
Serious hypersensitivity reactions require the discontinuation of the antibiotic, and may
require administration of epinephrine and other emergency measures.
Serious skin reactions, such as Stevens-Johnson syndrome and toxic epidermal
necrolysis, have been reported in patients receiving piperacillin/tazobactam (see section
4.8). If patients develop a skin rash they should be monitored closely and
piperacillin/tazobactam discontinued if lesions progress.

Precautions
Periodic assessment of organ system functions including renal and hepatic during
prolonged therapy is advisable.
Therapy with piperacillin/tazobactam may result in the emergence of resistant organisms,
which might cause super-infections.
Bleeding manifestations have occurred in some patients receiving β-lactam antibiotics.
These reactions have sometimes been associated with abnormalities of coagulation tests
such as clotting time, platelet aggregation and prothrombin time, and are more likely to
occur in patients
with renal failure. If bleeding manifestations occur, the antibiotic should
be discontinued and appropriate therapy instituted
Leukopenia and neutropenia may occur, especially during prolonged therapy. Therefore,

This medicinal product contains 9.44 mmol (217 mg) of sodium per vial of powder for
solution for injection or infusion. This should be taken into consideration for patients who
are on a controlled sodium diet.
Hypokalaemia may occur in patients with low potassium reserves or who are receiving
concomitant medications that may lower potassium levels; periodic electrolyte
determinations may be advisable in such patients
Modest elevation of indices of liver function may be observed.
Piperacillin therapy has been associated with an increased incidence of fever and rash in
cystic fibrosis patients (see also 4.8).
Until further experience is available, Tazo-Pip Avenir 4.5g should not be used in children
who do not have neutropenia.

4.5 Interaction with other medicinal products and other forms of interaction
Interaction with probenecid:
Concurrent administration of probenecid and piperacillin/tazobactam produced a longer
half-life and lower renal clearance for both piperacillin and tazobactam. However, peak
plasma concentrations of either drug are unaffected.
Interaction with antibiotics:
No clinically relevant adverse pharmacokinetic interaction with tobramycin or vancomycin
has been observed in healthy adults with a normal renal function. The clearance of
tobramycin and gentamicin was enhanced in patients with severe renal dysfunction using
piperacillin/tazobactam. In these patients mixing of piperacillin/tazobactam formulation
with tobramycin and gentamicin was excluded.
For information related to the administration of piperacillin/tazobactam with
aminoglycosides please refer to section 6.2.
Interaction with anticoagulants:
During simultaneous administration of heparin, oral anticoagulants and other drugs which
may affect the blood coagulation system including thrombocyte function, appropriate
coagulation tests should be performed
more frequently and monitored regularly.
Interaction with vecuronium:
Piperacillin when used concomitantly with vecuronium has been implicated in the
prolongation of the neuromuscular blockade of vecuronium. Due to their similar
mechanism of action, it is expected that the neuromuscular blockade produced by any of
the non-depolarizing muscle relaxants could be prolonged in the presence of piperacillin.
This should be taken into account when piperacillin/tazobactam is used peri-operatively.
Interaction with methotrexate:
Piperacillin may reduce the excretion of methotrexate. Serum levels of methotrexate
should be monitored in patients on methotrexate therapy.
Interaction with laboratory test results:The administration of piperacillin/tazobactam may
result in a false-positive reaction for glucose in the urine using a copper-reduction
method. It is recommended that glucose tests based on enzymatic glucose oxidase
reaction be used.
A number of chemical urine protein measurement methods may lead to false-positive
results. Protein measurement with dip sticks is not affected.
The direct Coombs test may be positive.
There have been reports of positive test results using the Bio-Rad Laboratories Platelia
Aspergillus EIA test in patients receiving piperacillin-tazobactam injection who were
subsequently found to be free of Aspergillus infection. Cross-reactions with non-
Aspergillus polysaccharides and polyfuranoses with Bio-Rad Laboratories Platelia
Aspergillus EIA test have been reported. Therefore, positive test results in patients
receiving piperacillin-tazobactam should be interpreted cautiously and confirmed by other
diagnostic methods.

4.6 Pregnancy and lactation
There are no adequate and well-controlled studies with piperacillin/tazobactam in
combination or with piperacillin or tazobactam alone in pregnant women. Studies in
animals have shown reproductive toxicity (see 5.3). Piperacillin and tazobactam cross the
placenta. Piperacillin/tazobactam should only be used during pregnancy if clearly
indicated i.e. only if the expected benefit outweighs the possible risks to the pregnant
woman and foetus.
Piperacillin is excreted in low concentrations in breast milk Tazobactam concentrations in
human milk have not been studied. The effect on the suckling infant is unknown. Women
who are breast-feeding should be treated only if clearly indicated. Diarrhoea and fungal
infections of the mucous membranes as well as sensitisation could occur in the breast-fed
infant.
A fertility study in rats showed no effect on fertility and mating after intraperitoneal
administration of tazobactam or the combination piperacillin / tazobactam (see section
5.3).

Chills
The administration of high doses of beta-lactams, particularly in patients with renal
insufficiency, can lead to encephalopathies (consciousness fluctuation, myoclonus and
convulsions).
Piperacillin therapy has been associated with an increased incidence of fever and rash in
cystic fibrosis patients.

4.9 Overdose
Symptoms
There have been post-marketing reports of overdose with Piperacillin/Tazobactam. The
majority of those events experienced including nausea, vomiting, and diarrhoea have also
been reported with the usual recommended dosages. Patients may experience
neuromuscular excitability or convulsions if higher than recommended doses are given
intravenously (particularly in the presence of renal failure).
Treatment of Intoxication
In the event of an overdose, Piperacillin/Tazobactam treatment should be discontinued.
No specific antidote is known.
Treatment should be supportive and symptomatic according to the patient's clinical
presentation. In the event of an emergency, all required intensive medical measures are
indicated as in the case of piperacillin.
Excessive serum concentrations of either piperacillin or tazobactam will be reduced by
haemodialysis (for more details see section 5.2).

5. PHARMACOLOGICAL PROPERTIES
Go to top of the page
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Combinations of penicillins, including beta-lactamase
inhibitors.
ATC Classification: J01CR05
Mechanism of action:
Piperacillin, a broad spectrum, semisynthetic penicillin active against many Gram-positive
and Gram-negative aerobic and anaerobic bacteria, exerts bactericidal activity by inhibition
of both septum and cell wall synthesis. Tazobactam, a triazolylmethyl penicillanic acid
sulphone, is a potent inhibitor of many beta-lactamases, in particular the plasmid mediated
enzymes which commonly cause resistance to penicillins and cephalosporins including
third-generation cephalosporins. The presence of tazobactam in the
Piperacillin/Tazobactam formulation enhances and extends the antibiotic spectrum of
piperacillin to include many beta-lactamase producing bacteria normally resistant to it and
other beta-lactam antibiotics. Thus, Piperacillin/Tazobactam combines the properties of a
broad spectrum antibiotic and a beta-lactamase inhibitor.
Mechanism of resistance:
The presence of tazobactam expands the spectrum of activity of piperacillin to include
microorganisms that would otherwise, due to the formation of beta-lactamase, be resistant
to piperacillin and other beta-lactam antibiotics. In vitro investigation has demonstrated that
the type I beta-lactamase inducing ability of tazobactam is insignificant with regard to Gram-
negative bacteria. In vitro studies have demonstrated a synergetic effect of
Piperacillin/Tazobactam and aminoglycosides against Pseudomonas aeruginosa and other
bacteria, including beta-lactamase producing strains.
Breakpoints
The minimum inhibitory concentration (MIC) breakpoints separating susceptible,
intermediately susceptible and resistant organisms have been defined as follows:
EUCAST clinical MIC breakpoints 2008 (version 1.2):
For susceptibility testing purposes, the concentration of tazobactam is fixed at 4
mg/L

Species-related breakpoints (S</R>)
Enterobacteriaceae
8/16
Pseudomonas

Gram-negative and Gram-positive anaerobes

The prevalence of acquired resistance may vary geographically and with time for selected
species and local information on resistance is desirable, particularly when treating severe
infections. As necessary, expert advice should be sought when the local prevalence of
resistance is such that the utility of the agent in at least some types of infections is
questionable.

5.2 Pharmacokinetic properties
Distribution
Peak piperacillin and tazobactam plasma concentrations are attained immediately after
completion of an intravenous infusion or injection. Piperacillin plasma levels produced
when given with tazobactam are similar to those attained when equivalent doses of
piperacillin are administered alone.
There is a greater proportional (approximately 28%) increase in plasma levels of
piperacillin and tazobactam with increasing dose over the dosage range of
piperacillin/tazobactam 2000/250 mg to piperacillin/tazobactam 4000/500 mg.
Both piperacillin and tazobactam are 20 to 30% bound to plasma proteins. The protein
binding of either piperacillin or tazobactam is unaffected by the presence of the other
compound. Protein binding of the tazobactam metabolite is negligible.
Piperacillin/Tazobactam is widely distributed in tissue and body fluids including intestinal
mucosa, gallbladder, lung, bile and bone.
Biotransformation
Piperacillin is metabolised to a minor microbiologically active desethyl metabolite.
Tazobactam is metabolised to a single metabolite, which has been found to be micro-
biologically inactive.
Elimination
Piperacillin and tazobactam are eliminated by the kidney via glomerular filtration and
tubular secretion.
Piperacillin is excreted rapidly as unchanged drug with 68% of the administered dose
appearing in the urine. Tazobactam and its metabolite are eliminated primarily by renal
excretion with 80% of the administered dose appearing as unchanged drug and the
remainder as the single metabolite. Piperacillin, tazobactam, and desethyl piperacillin are
also secreted into the bile.
Following single or multiple doses of Piperacillin/Tazobactam to healthy subjects, the
plasma half-life of piperacillin and tazobactam ranged from 0.7 to 1.2 hours and was
unaffected by dose or duration of infusion. The elimination half-lives of both piperacillin
and tazobactam are increased with decreasing renal clearance.
There are no significant changes in piperacillin pharmacokinetics due to tazobactam.
Piperacillin appears to reduce the rate of elimination of tazobactam.
Impaired Renal Function
Piperacillin and tazobactam are haemodialysable: 31% (piperacillin) and 39%
(tazobactam) of administered doses are filtrated. During peritoneal dialysis, 5% of
administered piperacillin and 12% of administered tazobactam are found in the dialysis
liquid. Patients treated by chronic ambulatory peritoneal dialysis should receive the same
dose as non dialysed patients with severe renal insufficiency.
Impaired Liver Function
Plasma concentrations of piperacillin and tazobactam are prolonged in hepatically
impaired patients. The half-life of piperacillin and of tazobactam increases by
approximately 25% and 18%, respectively, in patients with hepatic cirrhosis compared to
healthy subjects. However, dosage adjustments in patients with hepatic impairment are
not necessary.
Paediatric patients
The pharmacokinetics of Piperacillin/Tazobactam has been studied in paediatric patients
with intra-abdominal infections and other kinds of infections. In every age group, renal
fraction of elimination of piperacillin and tazobactam was approximately 70% and 80%,
respectively, like in adults.

5.3 Preclinical safety data
Preclinical data reveal no special hazard for humans based on conventional studies of
repeated dose toxicity and genotoxicity. Carcinogenicity studies have not been conducted
with piperacillin/tazobactam.
A fertility study of piperacillin/tazobactam reported a decrease in litter size and an
increase in fetuses with ossification delays and variations of ribs following i.p.
administration to rats. Fertility of the F1 generation and embryonic development of the F2
generation was not impaired. A teratogenicity study in rats, did not show teratogenic
effects after i.v. administration. In the rat, effects on the embryonic development were
observed at maternal toxic doses. Peri/postnatal development was impaired (reduced
fetal weights, increase in pup mortality, increase in stillbirths) concurrently with maternal
toxicity after i.p. administration in the rat.
