Pharmacological Properties

A combination antibacterial agent containing piperacillin, a broad-spectrum semi-synthetic antibiotic, and tazobactam, an inhibitor of most β-lactamases.

Pharmacodynamics. The mechanism of action of sodium piperacillin is due to inhibition of cell wall synthesis; the drug exhibits bactericidal activity. Sodium tazobactam is a β-lactamase inhibitor of Richmond-Sykes Class II: penicillinases and cephalosporinases. At recommended doses, tazobactam does not induce chromosomal β-lactamases.

The presence of tazobactam significantly extends the spectrum of piperacillin activity. The drug is active against most strains of microorganisms producing β-lactamases and resistant to piperacillin alone. The agent is active against a wide range of bacteria:

Pharmacokinetics. All pharmacokinetic parameters were similar following both separate and combined administration of piperacillin and tazobactam.

Adsorption. After intravenous administration, maximum plasma concentrations of piperacillin and tazobactam are achieved almost immediately. Following administration of 4 g of piperacillin sodium, the maximum plasma concentration is 298 μg/mL.

After administration of 500 mg of tazobactam sodium, the maximum plasma concentration is 34 μg/mL.

Uptake. Maximum plasma concentration (Cmax) is achieved immediately after intravenous injection.

Distribution. Protein binding is observed for both piperacillin and tazobactam and is approximately 30%. Piperacillin and tazobactam are widely distributed into tissues, including lungs, female reproductive organs (uterus, ovaries, fallopian tubes), gallbladder, bile, intestinal mucosa, and interstitial fluid. Tissue concentrations generally range from 50% to 100% compared to plasma levels. Distribution of piperacillin and tazobactam into cerebrospinal fluid is low in the absence of meningeal inflammation.

Biotransformation. Piperacillin is metabolized to a desethyl metabolite, which exhibits weak microbiological activity. Tazobactam is metabolized to a single microbiologically inactive metabolite.

Metabolism. Piperacillin is metabolized to a desethyl metabolite, which exhibits antimicrobial activity. Tazobactam is metabolized to a single metabolite that lacks pharmacological and antibacterial activity.

Elimination. After single or multiple doses of piperacillin/tazobactam in healthy volunteers, the plasma elimination half-life ranged from 0.7 to 1.2 hours. Dose and infusion duration did not affect this parameter. The elimination half-life of both piperacillin and tazobactam increased with decreased renal clearance.

Administration of tazobactam did not significantly affect the pharmacokinetics of piperacillin. Piperacillin reduces the elimination rate of tazobactam. Both piperacillin and tazobactam are eliminated by the kidneys via glomerular filtration and tubular secretion. Piperacillin is rapidly eliminated as it is a hydrophilic drug. Approximately 68% of the dose is excreted in urine. Tazobactam and its metabolites are primarily (about 80%) eliminated by the kidneys.

Patients with impaired renal function. The elimination half-life of piperacillin and tazobactam increases as creatinine clearance decreases. The half-life increases two- and four-fold for piperacillin and tazobactam, respectively, when creatinine clearance is less than 20 mL/min, compared to patients with normal renal function. Hemodialysis removes 30–50% of Zopercin® and an additional 5% of the tazobactam dose as metabolite. Peritoneal dialysis removes 6–21% of piperacillin and tazobactam, respectively, and an additional 18% of tazobactam as metabolite.

Patients with impaired hepatic function. In patients with impaired liver function, plasma concentrations of piperacillin and tazobactam increase. The elimination half-life of piperacillin and tazobactam increases by approximately 25% and 18%, respectively, in patients with liver cirrhosis compared to healthy volunteers. However, dosage adjustment of the drug is not required in patients with impaired liver function.

Pediatric patients. The pharmacokinetics of Zopercin® were studied in children with intra-abdominal and other types of infections. In each age group, renal excretion of piperacillin and tazobactam accounted for approximately 70% and 80%, respectively, similar to that observed in adults.

Clinical characteristics.

Indications.

Zopercin® is indicated for the treatment of the following infections in adults and children aged 2 years and older.

Adults and adolescents.

  • Severe pneumonia, including nosocomial and ventilator-associated pneumonia;
  • Complicated urinary tract infections (including pyelonephritis);
  • Complicated intra-abdominal infections;
  • Complicated skin and soft tissue infections (including diabetic foot syndrome).

Treatment of patients with bacteremia associated or likely associated with any of the above-mentioned infections.

Zopercin® may be used for the treatment of patients with febrile neutropenia, likely caused by a bacterial infection.

Children aged 2–12 years.

  • Complicated intra-abdominal infections.

Zopercin® may be used for the treatment of children with febrile neutropenia, likely caused by a bacterial infection.

Attention should be paid to official guidelines on the appropriate use of antibacterial agents.

Contraindications.

Hypersensitivity reactions to any penicillins, cephalosporins, or β-lactamase inhibitors.

Special safety precautions.

Serious and sometimes fatal hypersensitivity reactions (anaphylactic/anaphylactoid, including shock) have been reported during therapy with penicillin-group agents, including Zopercin®. Patients with a history of hypersensitivity to multiple allergens are most susceptible to such reactions.

Severe reactions have also been reported during treatment with cephalosporins in patients with a history of penicillin hypersensitivity. If allergic reactions occur during therapy with Zopercin®, the drug should be discontinued immediately. Serious hypersensitivity reactions may require administration of epinephrine or other emergency measures.

Prior to initiating therapy with Zopercin®, a thorough patient history should be obtained regarding previous allergic reactions to penicillins, cephalosporins, and other allergens.

In case of severe, persistent diarrhea, pseudomembranous colitis, which may be life-threatening and is caused by antibiotic-associated microorganisms, should be considered.
Symptoms may appear during or after antibacterial therapy. In such cases, the drug should be discontinued immediately and appropriate treatment initiated (e.g., oral metronidazole or vancomycin). Antiperistaltic agents are contraindicated.

Interaction with other medicinal products and other forms of interaction.

Probenecid. Concomitant administration of probenecid and Zopercin® results in prolonged elimination half-life and reduced renal clearance of both piperacillin and tazobactam. However, this does not affect the maximum plasma concentration of either agent.

Antibiotics. Piperacillin alone or in combination with tazobactam does not cause clinically significant changes in the pharmacokinetics of tobramycin in patients with normal renal function or mild to moderate renal impairment. Tobramycin administration did not significantly alter the pharmacokinetics of piperacillin, tazobactam, or metabolite M1. No clinically significant interaction between the pharmacokinetics of Zopercin® and vancomycin has been observed in healthy adult volunteers with normal renal function.

Due to physical incompatibility between aminoglycosides and beta-lactam antibiotics in vitro, Zopercin® and aminoglycosides must not be mixed. They should be administered separately. When combination therapy is prescribed, the powder for injection solution of Zopercin® and the aminoglycoside should be reconstituted and diluted separately.

Anticoagulants. When used concomitantly with heparin, oral anticoagulants, and other agents affecting the blood coagulation system, including platelet function, coagulation tests should be monitored regularly.

Vecuronium. Concomitant administration of piperacillin with vecuronium results in prolonged neuromuscular blockade. Due to a similar mechanism of action, neuromuscular blockade induced by any non-depolarizing neuromuscular blocking agent may be prolonged by piperacillin administration. This should be considered when using Zopercin® during surgical procedures.

Methotrexate. Piperacillin may reduce methotrexate elimination. Serum methotrexate levels should be monitored in patients receiving methotrexate.

Effect on laboratory tests. As with other penicillin-group agents, administration of Zopercin® may result in false-positive urine glucose tests (when using reduction methods). Enzymatic glucose oxidase-based tests for glucose detection are recommended.

Positive results in the Platelia Aspergillus ELISA (enzyme-linked immunosorbent assay) test by Bio-Rad Laboratories have been reported in patients receiving Zopercin® injections, despite no subsequent diagnosis of aspergillosis. Cross-reactions with non-aspergillus polysaccharides and polyfuranoses in the Platelia Aspergillus ELISA test by Bio-Rad Laboratories have also been reported. Therefore, positive test results in patients receiving Zopercin® should be interpreted cautiously and confirmed by other diagnostic methods.

Special precautions for use.

Since leukopenia and neutropenia may develop during prolonged therapy, periodic monitoring of blood parameters is recommended.

When high doses of the drug are administered (especially in patients with impaired renal function), neurological complications such as seizures may occur, similar to those observed with other penicillin-class antibiotics. During long-term treatment, renal and hepatic function should be periodically monitored.

In some patients receiving beta-lactam antibiotics, symptoms of bleeding have been observed. Such reactions were sometimes associated with coagulation disorders, including blood clotting time, platelet aggregation, and prothrombin time. These abnormalities were most frequently observed in patients with renal impairment. If bleeding occurs, antibiotic administration should be discontinued and appropriate treatment initiated.

As with other antibiotics, one should always remain alert to the possibility of needing to provide emergency interventions, particularly during prolonged treatment.

Microbiological testing may be required to detect any superinfection. Appropriate measures should be taken if signs of superinfection appear.

As with other penicillin-class antibiotics, exceeding recommended doses may lead to neuromuscular excitability or seizures in patients.

Zopercin® contains 216 mg (9.4 mEq) of sodium per 4.5 g vial; therefore, administration of the drug may increase the total body sodium load. This should be taken into account in patients on a low-sodium diet.

Hypokalemia may develop in patients with low potassium levels or in those receiving potassium-depleting agents. In such patients, periodic monitoring of electrolyte balance is necessary.

Slight elevations in liver function test parameters may occur.

Antimicrobial agents administered in high doses over a short period for the treatment of gonorrhea may mask or delay the symptoms of syphilis. Therefore, patients with gonorrhea should be tested for syphilis prior to initiating treatment. In patients with primary lesions, dark-field microscopy should be performed, and serological tests should be repeated at 6 weeks and 3 months.

When penicillins (particularly piperacillin) are used in patients with cystic fibrosis, fever and rash may occur.

Use during pregnancy or breastfeeding

Pregnancy. There are currently no adequate and well-controlled studies of piperacillin/tazobactam combination, or of piperacillin or tazobactam alone, conducted in pregnant women. Zopercin® crosses the placenta. The drug should be used during pregnancy only if the potential benefit justifies the potential risk to the woman and the fetus.

Breastfeeding period. Piperacillin is excreted in breast milk in low concentrations; the concentration of tazobactam in breast milk has not been studied. Breastfeeding is not recommended during treatment.

Effect on ability to drive or operate machinery.

The effect of the drug on the ability to drive or operate machinery has not been established.

Administration and Dosage

The medicinal product should be administered slowly by intravenous infusion over more than 30 minutes.

The dose and frequency of administration of Zopercin® depend on the severity and location of the infection, as well as the likely causative pathogens.

Adults and children aged 12 years and older (with body weight over 50 kg) with normal renal function. The usual dose for adults and children aged 12 years and older is 4.5 g of Zopercin® (4 g piperacillin / 0.5 g tazobactam) every 8 hours.

In neutropenic patients and in severe pneumonia, the recommended dose of Zopercin® (4 g piperacillin / 0.5 g tazobactam) is 4.5 g every 6 hours.

This dosing regimen may also be used for the treatment of patients with other complicated conditions associated with acute infection.

Recommended administration frequencies for adult and adolescent patients are listed in Table 3.

Geriatric patients with normal renal function. Piperacillin and tazobactam may be administered to geriatric patients in the same dosage as for adults, except for patients with renal impairment (see below).

Renal impairment in adults, geriatric patients, and children. For patients with renal impairment, the intravenous dose of the drug should be adjusted according to the degree of renal function impairment (each patient must be carefully monitored for signs of toxicity; the drug dose and dosing interval should be adjusted accordingly; see Table 4).

Due to hemodialysis removing 30–50 % of piperacillin within 4 hours, an additional dose of 2 g/0.25 g of piperacillin/tazobactam should be administered after each dialysis session. For patients with renal and hepatic insufficiency, monitoring of serum piperacillin/tazobactam levels will ensure adequate dose adjustment.

Children aged 2 to 12 years with normal renal function and body weight less than 50 kg.

Neutropenia. The dose should be adjusted to 90 mg/kg (80 mg piperacillin/10 mg tazobactam) administered every 6 hours in combination with aminoglycosides, not exceeding 4.5 g (4 g piperacillin/0.5 g tazobactam) every 6 hours.

Complicated intra-abdominal infections. For treatment of children aged 2 to 12 years, the dose should be adjusted to 112.5 mg/kg (100 mg piperacillin/12.5 mg tazobactam) administered every 8 hours, not exceeding 4.5 g (4 g piperacillin/0.5 g tazobactam) every 8 hours.

Since experience with Zopercin® in pediatric patients is limited, it is primarily used in this population for the treatment of neutropenia or complicated forms of acute appendicitis.

Renal insufficiency in children up to 12 years of age. In children with renal insufficiency, the intravenous dose of the drug should be adjusted according to the renal function status (see Table 5).

For children with body weight <50 kg undergoing hemodialysis, an additional dose of 40 mg piperacillin/5 mg tazobactam per kg should be administered after each dialysis session.

Patients should be carefully monitored and observed for symptoms of drug toxicity. The dose and dosing interval should be adjusted accordingly.

Use in children under 2 years of age. The safety and efficacy of this medicinal product in children under 2 years of age have not been established. There are no published data from controlled clinical trials.

Patients with hepatic impairment. In most cases, dose adjustment is not required.

If necessary, in patients with renal and hepatic impairment, measuring serum levels of piperacillin and tazobactam allows appropriate dose adjustment.

Duration of treatment. The duration of treatment should be determined based on the patient's condition, severity of infection, results of bacteriological examination, and current regulatory documents and guidelines on rational antibiotic therapy.

Typically, the duration of treatment course ranges from 5 to 14 days.

Instructions for solution preparation.

The contents of a vial containing 4 g/0.5 g of piperacillin/tazobactam should be reconstituted with 20 mL of one of the following diluents.

After reconstitution, the solution should be further diluted to the desired volume (from 50 mL to 150 mL) using one of the following diluents:

  • ● 0.9% sodium chloride injection solution;
  • ● 5% aqueous glucose solution;
    • sterile water for injection (maximum recommended volume for a single dose is 50 mL).

The prepared solution should preferably be used immediately.

Volume displacement. 1 gram of piperacillin/tazobactam crystalline powder has a volume displacement of 0.7 mL.

  2. The infusion bottle must be labeled with the patient’s full name, name and amount of the added diluent, date and time of preparation, and, if possible, the expiration date or time.

  3. The intravenous infusion process should be monitored periodically. If cloudiness, crystallization, discoloration, or any other signs of drug interaction or contamination occur, the infusion must be discontinued.

  4. The duration of intravenous infusion should be at least 30 minutes.

If the prepared solution is not used immediately, the healthcare professional responsible for subsequent administration is responsible for the storage conditions and duration until administration.

Any unused solution must be disposed of (destroyed).

Children. The drug is indicated for children aged 2 years and older.

Overdose.

Symptoms. Overdose cases have been reported in post-marketing studies. Most of these cases, which were accompanied by nausea, vomiting, and diarrhea, occurred following administration of the usual recommended doses. Nervous system and muscular excitation or seizures may occur in patients receiving doses exceeding the recommended intravenous doses (especially in patients with renal impairment).

Treatment. In case of overdose, further administration of piperacillin/tazobactam should be discontinued. There is no known specific antidote.

Treatment is supportive and symptomatic, depending on the patient’s condition. In emergency situations, intensive care measures should be implemented, similar to those used in piperacillin overdose.

Excess serum concentrations of piperacillin or tazobactam can be reduced by hemodialysis.

In case of motor excitation or seizures, anticonvulsant agents (e.g., diazepam or barbiturates) may be administered.

In case of severe anaphylactic reactions, standard emergency measures should be initiated.
