Pharmacological Properties
Pharmacodynamics
Ceftazidime is a bactericidal cephalosporin antibiotic whose mechanism of action is related to disruption of bacterial cell wall synthesis.
Acquired resistance to the antibiotic varies in different regions and may change over time, with significant differences observed among individual strains. Local data on antibiotic susceptibility and the prevalence of microorganisms producing extended-spectrum beta-lactamases should be consulted, especially when treating severe infections.
Susceptible microorganisms
Gram-positive aerobes: Streptococcus pyogenes, Streptococcus agalactiae.
Gram-negative aerobes: Citrobacter koseri, Haemophilus influenzae, Moraxella catarrhalis, Neisseria meningitidis, Proteus mirabilis, Proteus spp., Providencia spp., Pasteurella multocida.
Strains with potential acquired resistance
Gram-negative aerobes: Acinetobacter baumannii, Burkholderia cepacia, Citrobacter freundii, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Klebsiella spp., Pseudomonas aeruginosa, Serratia spp., Morganella morganii.
Gram-positive aerobes: Staphylococcus aureus, Streptococcus pneumoniae, Viridans group streptococcus.
Gram-positive anaerobes: Clostridium perfringens, Peptococcus spp., Peptostreptococcus spp.
Gram-negative anaerobes: Fusobacterium spp.
Resistant microorganisms
Gram-positive aerobes: Enterococcus spp., including E. faecalis and E. faecium, Listeria spp.
Gram-positive anaerobes: Clostridium difficile.

Pharmacokinetics
After intramuscular injection of 500 mg and 1 g, mean peak serum concentrations of 18 mg/L and 37 mg/L are rapidly achieved, respectively. Within 5 minutes after intravenous bolus administration of 500 mg, 1 g, or 2 g, mean serum concentrations of 46 mg/L, 87 mg/L, or 170 mg/L are achieved, respectively. Therapeutically effective concentrations persist in serum for up to 8–12 hours after intravenous or intramuscular administration. Plasma protein binding is approximately 10%. Therapeutic concentrations exceeding the MIC (minimum inhibitory concentration) for most common pathogenic microorganisms are achieved in tissues and body fluids such as bone, heart, bile, sputum, intraocular fluid, synovial fluid, pleural fluid, and peritoneal fluid. Ceftazidime rapidly crosses the placenta and is excreted into breast milk. The drug poorly penetrates the intact blood-brain barrier; in the absence of inflammation, concentrations in the central nervous system (CNS) are low. However, during meningitis, ceftazidime concentrations in the CNS range from 4–20 mg/L or higher, which corresponds to therapeutic levels. Ceftazidime is not metabolized in the body. After parenteral administration, high and sustained serum concentrations are achieved. The elimination half-life is approximately 2 hours. The drug is excreted unchanged and in active form via the kidneys by glomerular filtration; approximately 80–90% of the dose is recovered in urine within 24 hours. In patients with impaired renal function, elimination of ceftazidime is reduced, and dosage adjustment is required. Less than 1% of the drug is excreted in bile, significantly limiting the amount reaching the intestinal tract.
Clinical Characteristics
Indications
Treatment of the following infections in adults and children, including newborns:
- Hospital-acquired pneumonia;
- Respiratory tract infections in patients with cystic fibrosis;
- Bacterial meningitis;
- Chronic suppurative otitis media;
- Malignant external otitis;
- Complicated urinary tract infections;
- Complicated skin and soft tissue infections;
- Complicated intra-abdominal infections;
- Bone and joint infections;
- Peritonitis associated with dialysis in patients undergoing continuous ambulatory peritoneal dialysis.
Treatment of bacteremia arising from any of the above-mentioned infections.
Ceftazidime may be used for the treatment of patients with neutropenia and fever suspected to be due to a bacterial infection.
Ceftazidime may be used for prophylaxis of urinary tract infections during urological procedures (transurethral resection of the prostate).
When prescribing ceftazidime, consideration should be given to its antibacterial spectrum, which is primarily directed against aerobic Gram-negative bacteria (see sections “Pharmacological properties” and “Special precautions”).
Ceftazidime should be used in combination with other antibacterial agents if a range of microorganisms causing the infection are not covered by the spectrum of ceftazidime.
The drug should be prescribed in accordance with current official guidelines for the use of antibacterial agents.
Contraindications
Hypersensitivity to ceftazidime or to any of the excipients of the medicinal product.
Hypersensitivity to other cephalosporin antibiotics.
History of severe hypersensitivity (e.g., anaphylactic reactions) to other beta-lactam antibiotics (penicillins, monobactams, and carbapenems).
Interaction with other medicinal products and other types of interactions
Concomitant administration of high doses of ceftazidime with nephrotoxic medicinal products may adversely affect renal function (see section “Special precautions”).
Chloramphenicol is an in vitro antagonist of ceftazidime and other cephalosporins. The clinical significance of this phenomenon is unknown; however, if concomitant use of ceftazidime and chloramphenicol is considered, potential antagonism should be taken into account.
Like other antibiotics, ceftazidime may affect intestinal flora, leading to reduced reabsorption of estrogens and decreased efficacy of combined oral contraceptives. Ceftazidime does not interfere with glucose in urine testing by enzymatic methods; however, a minor interference may be observed when using copper reduction methods (Benedict’s, Fehling’s, Clinitest).
Ceftazidime does not interfere with creatinine measurement by the alkaline picrate method.
Special precautions for use
Severe skin adverse reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), have been reported with ceftazidime treatment, which may be life-threatening or lead to fatal outcomes (frequency unknown). Patients should be informed about the signs and symptoms, and careful monitoring for skin reactions is required. If symptoms indicating such reactions occur, ceftazidime should be discontinued immediately and alternative therapy considered. If a serious reaction such as SJS, TEN, DRESS, or AGEP develops during ceftazidime treatment, re-administration of ceftazidimed must be avoided under any circumstances.
Severe and sometimes fatal hypersensitivity reactions have been reported with the use of beta-lactam antibiotics, including ceftazidime. In case of severe hypersensitivity reactions, ceftazidime therapy should be discontinued immediately and appropriate emergency measures initiated.
Prior to initiating therapy, patients should be questioned about previous history of severe hypersensitivity reactions to ceftazidime, cephalosporin antibiotics, or other beta-lactam antibiotics. The drug should be administered with caution to patients who have experienced mild hypersensitivity reactions to other beta-lactam antibiotics.
Ceftazidime has a limited antibacterial spectrum. It is not an appropriate agent for monotherapy of certain types of infections unless the causative pathogen has been shown to be susceptible to ceftazidime, or there is a high likelihood that the likely pathogen will be susceptible. This is particularly important when considering treatment of patients with bacteremia, bacterial meningitis, skin and soft tissue infections, and bone and joint infections. Furthermore, ceftazidime is susceptible to hydrolysis by certain extended-spectrum beta-lactamases. Therefore, when selecting ceftazidime for treatment, information regarding the prevalence of microorganisms producing extended-spectrum beta-lactamases should be taken into account.
Concomitant treatment with high doses of cephalosporins and nephrotoxic agents such as aminoglycosides or potent diuretics (e.g., furosemide) may adversely affect renal function. Clinical experience with ceftazidime has shown that this phenomenon is unlikely when recommended dosages are followed. There are no data indicating that ceftazidime adversely affects renal function at usual therapeutic doses.
Ceftazidime is eliminated by the kidneys; therefore, the dose should be reduced according to the degree of renal impairment. Cases of neurological complications have been reported when the dose was not appropriately reduced (see sections "Dosage and administration" and "Side effects").
As with other broad-spectrum antibiotics, prolonged treatment with ceftazidime may lead to overgrowth of non-susceptible microorganisms (e.g., Candida, Enterococci); in such cases, discontinuation of treatment or other necessary measures may be required. Continuous monitoring of the patient's condition is essential.
Cases of pseudomembranous colitis, ranging from mild to life-threatening, have been reported with antibiotic use. Therefore, this diagnosis should be considered in patients who develop diarrhea during or after antibiotic therapy. If prolonged and severe diarrhea or abdominal cramps occur, treatment should be discontinued immediately, further investigations performed, and specific therapy for Clostridium difficile initiated if necessary. Medicinal products that inhibit intestinal peristalsis should not be administered.
As with other broad-spectrum cephalosporins and penicillins, some previously susceptible strains of Enterobacter spp. and Serratia spp. may become resistant during ceftazidime therapy. In such cases, periodic susceptibility testing should be performed.
The medicinal product contains sodium, which should be taken into account when treating patients on a sodium-restricted diet.
Use during pregnancy or breastfeeding
Data on ceftazidime use in pregnant women are limited. Animal studies do not indicate any direct or indirect harmful effects on pregnancy, embryonic or postnatal development. The drug should be administered to pregnant women only if the potential benefit outweighs the possible risk.
Ceftazidime is excreted in breast milk in small amounts, but effects on the breastfed infant are not expected with therapeutic doses. Ceftazidime may be used during breastfeeding.
Ability to influence the ability to drive and use machines
No specific studies have been conducted. However, certain adverse reactions (e.g., dizziness) may occur, which could affect the ability to drive or operate machinery (see section "Side effects").

Children
The safety and efficacy of ceftazidime administered by continuous intravenous infusion in infants and children ≤ 2 months of age have not been established.
Geriatric patients
Due to reduced ceftazidime clearance, for elderly patients with acute infections, the daily dose generally should not exceed 3 g, especially for patients aged 80 years and older.
Hepatic impairment
Dosage adjustment is not required for patients with mild to moderate hepatic impairment. Clinical studies in patients with severe hepatic impairment have not been conducted. Careful clinical monitoring of efficacy and safety of use is recommended.
Renal impairment
Ceftazidime is excreted unchanged by the kidneys. Therefore, the dose should be reduced in patients with impaired renal function.
The initial loading dose should be 1 g. The maintenance dose should be based on creatinine clearance.

Dosing should be performed cautiously. Careful clinical monitoring of efficacy and safety of use is recommended.
Children with body weight < 40 kg
The safety and efficacy of ceftazidime administered by continuous intravenous infusion in children with body weight < 40 kg and impaired renal function have not been established. Careful clinical monitoring of efficacy and safety of use is recommended.
If children with impaired renal function require administration of the medicinal product by continuous intravenous infusion, creatinine clearance should be adjusted according to the child's body surface area or body weight.
Hemodialysis
The elimination half-life of ceftazidime in serum during hemodialysis is 3 to 5 hours.
A maintenance dose of ceftazidime, as recommended in tables 6–7 below, should be administered after each hemodialysis session.
Peritoneal dialysis
Ceftazidime can be used during peritoneal dialysis, including continuous ambulatory peritoneal dialysis.
In addition to intravenous administration, ceftazidime can be added to dialysis fluid (typically 125 mg to 250 mg per 2 L of dialysis solution).
For patients with renal insufficiency undergoing prolonged arteriovenous hemofiltration or high-flux hemofiltration in intensive care units, the recommended dose is 1 g daily as a single dose or divided doses. For low-flux hemofiltration, doses should be as for impaired renal function.
Dosing recommendations for patients undergoing venovenous hemofiltration and venovenous hemodialysis are provided in tables 6–7.

and the maintenance dose should be administered every 12 hours.
Administration
The medicinal product should be administered intravenously by injection or infusion, or by deep intramuscular injection. Recommended sites for intramuscular administration are the upper outer quadrant of the gluteus maximus muscle or the lateral aspect of the thigh.
Ceftazidime solutions may be administered directly into the vein or into an intravenous infusion system, if the patient is receiving parenteral fluids.
The dosage depends on the severity of the infection, the susceptibility, site, and type of infection, as well as the patient's age and renal function.
Preparation of the solution
Ceftazidime is compatible with most commonly used intravenous infusion solutions. However, sodium bicarbonate for injection should not be used as a solvent (see section "Incompatibilities").
All vials are under reduced pressure. Carbon dioxide is released during reconstitution, leading to increased pressure in the vial. Small bubbles of carbon dioxide in the reconstituted solution can be disregarded.

* Reconstitution for intravenous infusion should be performed in two steps (see text below).
The color of the solution may vary from light yellow to amber depending on concentration, diluent, and storage conditions. Provided that the recommendations are followed, the drug's activity is not affected by variations in its coloration.
Ceftazidime at concentrations from 1 mg/mL to 40 mg/mL is compatible with the following solutions: 0.9% sodium chloride solution; M/6 sodium lactate solution; Hartmann's solution; 5% glucose solution; 0.225% sodium chloride and 5% glucose solution; 0.45% sodium chloride and 5% glucose solution; 0.9% sodium chloride and 5% glucose solution; 0.18% sodium chloride and 4% glucose solution; 10% glucose solution; 10% glucose 40 and 0.9% sodium chloride solution; 10% glucose 40 and 5% glucose solution; 6% dextran 70 and 0.9% sodium chloride solution; 6% dextran 70 and 5% glucose solution.
Ceftazidime at concentrations from 0.05 mg/mL to 0.25 mg/mL is compatible with peritoneal dialysis fluid (lactate).
Ceftazidime for intramuscular administration may be dissolved in 0.5% or 1% lidocaine hydrochloride solution.
The stability of both agents is maintained when mixing ceftazidime at a concentration of 4 mg/mL with the following substances: hydrocortisone (hydrocortisone sodium phosphate) 1 mg/mL in 0.9% sodium chloride injection or 0.5% glucose solution; cefuroxime (cefuroxime sodium) 3 mg/mL in 0.9% sodium chloride injection; cloxacillin (cloxacillin sodium) 4 mg/mL in 0.9% sodium chloride injection; heparin 10 IU/mL or 50 IU/mL in 0.9% sodium chloride injection; potassium chloride 10 mEq/L or 40 mEq/L in 0.9% sodium chloride injection.
The contents of the Medacete-1000 vial, reconstituted with 1.5 mL of water for injections, may be added to a metronidazole solution (500 mg in 100 mL), with both drugs retaining their activity.
Preparation of solutions for intramuscular or intravenous bolus injection
- Insert the needle of the syringe through the vial stopper and add the recommended volume of diluent.
- Remove the syringe needle and shake the vial until a clear solution is obtained.
- Invert the vial. With the syringe plunger fully depressed, insert the needle into the vial. Withdraw the entire solution into the syringe, ensuring the needle remains in the solution at all times. Small bubbles of carbon dioxide may be disregarded.
Preparation of solutions for intravenous infusion
- Insert the needle of the syringe through the vial stopper and add 10 mL of diluent.
- Remove the syringe needle and shake the vial until a clear solution is obtained.
- Do not insert an air vent needle through the stopper until the drug is completely dissolved. After complete dissolution, insert an air vent needle through the stopper into the vial to relieve internal pressure.
- Add the resulting solution to an intravenous infusion system, making up to a total volume of at least 50 mL, and administer by intravenous infusion over 15–30 minutes.
Note. To ensure sterility of the preparation, it is essential not to insert an air vent needle through the stopper before the drug is fully dissolved.
The prepared solution may be stored for up to 24 hours at temperatures below 25°C or for up to 7 days at temperatures up to 4°C.
Children
Can be administered to children from the first days of life.
Overdose
Overdose may lead to neurological complications such as encephalopathy, seizures, and coma. Symptoms of overdose may occur in patients with renal impairment if the dose is not appropriately reduced (see sections "Dosage and administration" and "Special precautions"). Serum concentrations of ceftazidime can be reduced by hemodialysis or peritoneal dialysis.
Adverse Reactions
Adverse reactions are classified by organ systems and frequency of occurrence: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000); frequency not known (cannot be estimated from available data).

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after medicine authorization is important. It allows continued monitoring of the benefit-risk balance of the medicine. Healthcare professionals, pharmacists, patients, or their legal representatives should report all suspected adverse reactions and lack of efficacy through the Automated Pharmacovigilance Information System at: https://aisf.dec.gov.ua.
Shelf life. 2 years.
Storage conditions
Store at temperatures not exceeding 30 °C in the original packaging.
Keep out of the reach of children.
Incompatibilities
Ceftazidime is less stable in solutions of sodium bicarbonate for injection than in other intravenous solutions and therefore is not recommended as a solvent.
Ceftazidime and aminoglycosides should not be mixed in the same infusion system or syringe.
Precipitation has been observed when vancomycin was added to a ceftazidime solution. Therefore, infusion systems and intravenous catheters should be flushed between administration of these two drugs.
