Overview of Зацеф

What is Зацеф? (Overview)

Property Description
Active Ingredient Ceftazidime (INN)
Pharmacological Class Third-Generation Cephalosporin Antibiotic
Mechanism Principle Bactericidal (Kills bacteria)
Form Sterile dry-powdered mixture (for injection)
Origin Semisynthetic beta-lactam compound

Defining the Third-Generation Cephalosporin Class

Зацеф is a prescription-only semisynthetic beta-lactam antibiotic whose active ingredient, Ceftazidime, is classified within the third-generation cephalosporin pharmacological group. This class of antibiotic is clinically recognized for its robust broad-spectrum capability, particularly against problematic Gram-negative bacteria.

The Ceftazidime molecule is unique among many third-generation cephalosporins because it maintains superior activity against pathogens like Pseudomonas aeruginosa. This targeted efficacy is supported by pharmacological studies and is why the drug remains a critical agent in managing complex infections where bacterial resistance may be a concern.

Composition and Injectable Form

The drug is supplied as a single-agent product, presented as a sterile dry-powdered mixture for injection, comprising the key component, Ceftazidime (often as the pentahydrate or sodium salt). This formulation necessitates parenteral administration—either Intravenous (IV) use or Intramuscular (IM) use—after the powder for injection is prepared as a solution for injection.

Like many cephalosporins, Ceftazidime is not adequately absorbed when taken by mouth. This method of delivery ensures immediate systemic availability, which is vital for achieving therapeutic concentrations rapidly in critically ill patients.

Purpose: An Antibacterial Drug for Severe Infections

Зацеф’s essential function is to exert a rapid, direct bactericidal action, meaning it actively destroys the target pathogens. It achieves this by the inhibition of bacterial cell wall synthesis. This established molecular effect confirms its core general purpose: to serve as a reliable agent for controlling a range of bacterial infections, enabling the patient's recovery from potentially life-threatening infections in both adult and pediatric patients.

What side effects are possible with Зацеф?

Possible Side Effects and Safety Information

The safety profile of Зацеф (Ceftazidime) is officially defined by government regulatory agencies through classifications based on the frequency and type of documented adverse reactions. These classifications help categorize the risks associated with treatment.

Frequency-Classified Adverse Reactions

Adverse reactions are formally grouped by regulatory authorities:

  • Common (1% to 10%): Reactions at the injection or infusion site (e.g., phlebitis, pain, inflammation), gastrointestinal effects such as diarrhea, and changes in laboratory parameters, including eosinophilia, thrombocytosis, and transient elevations of liver enzymes.
  • Uncommon (0.1% to 1%): Less frequently reported effects involve hematological changes like leukopenia or neutropenia, neurological symptoms such as headache and dizziness, and skin reactions like rash or pruritus.
  • Incidence Not Known (Postmarketing/Very Rare): Effects reported through postmarketing surveillance that are potentially life-threatening but have an undetermined incidence rate, including severe skin reactions (Stevens-Johnson syndrome, Toxic Epidermal Necrolysis), and neurological sequelae like seizures, encephalopathy, and coma.

System-Organ-Class Safety Summary

Adverse reactions are grouped by the affected physiological system, including Blood and Lymphatic System Disorders, Gastrointestinal Disorders (which includes Clostridioides difficile-associated diarrhea (CDAD)), Nervous System Disorders, and Immune System Disorders.

Serious Adverse Reactions and Restrictions

Certain adverse reactions are specifically highlighted as serious and clinically significant. These include Anaphylaxis and severe hypersensitivity reactions, as well as the potential for CDAD, which may occur during or months following treatment. The medication is contraindicated in patients with a known history of serious hypersensitivity to Ceftazidime or to other cephalosporin-class antibacterial drugs. Additionally, regulatory documents note that patients with pre-existing renal impairment are at an increased risk of Neurological Adverse Reactions due to slower drug clearance.

Overdose and Emergency Response

Overdose and When to Seek Help

Official regulatory information describes the overdose profile of Ceftazidime (Зацеф) as primarily involving severe central nervous system (CNS) manifestations. These documented outcomes are considered the most significant consequences of an overdosage.

Documented Manifestations and Risks

Domain Official Regulatory Statements
Documented CNS Overdose Signs Overdosage has been associated with CNS effects including seizure activity, encephalopathy, asterixis, and neuromuscular excitability.
Severe Outcomes The CNS effects can progress to severe outcomes, including coma and generalized seizure activity (convulsions).
Population-Specific Risk Overdosage, resulting in neurotoxicity, has been specifically documented in patients with renal failure (impaired renal function). The risk of toxic reactions is stated to be greater in this population.

Emergency Actions and Management

Official government guidance mandates specific immediate actions for severe symptoms:

  • Immediate Medical Help: Regulatory bodies advise immediately calling emergency services (such as 911 or the local equivalent) if the affected person collapses, experiences a seizure, has trouble breathing, or cannot be awakened.
  • Supportive Treatment: Patients who have received an overdosage should be carefully observed and managed with supportive treatment.
  • Drug Removal Procedure: Hemodialysis or peritoneal dialysis may aid in the removal of the drug from the body, particularly in cases involving compromised renal function.
  • Antidote Status: No specific antidote is officially known or documented for Ceftazidime overdosage.

What should I know about interactions with other medicines?

Interactions with other medicines and products

This section describes the officially documented interaction patterns for Ceftazidime (Зацеф) as outlined in government regulatory information, focusing strictly on formal outcomes and administration restrictions.

Pharmacodynamic and Toxicity Interactions

Co-administration with specific medicinal products results in documented pharmacodynamic effects or increased toxicity potential:

  • Aminoglycosides: There is an increased potential for nephrotoxicity (kidney damage) and ototoxicity (inner ear damage) when Ceftazidime is given concurrently with aminoglycoside antibiotics.
  • Chloramphenicol: This combination should be avoided when bactericidal action is required, as in vitro studies show antagonistic effects that may compromise the intended antibiotic action.

Administration and Efficacy Restrictions

Specific rules for timing and co-administration are mandated to prevent physical incompatibility or reduced efficacy of other medicines:

  • Timing Separation: Solutions of Ceftazidime and aminoglycoside antibiotics must be administered separately and sequentially due to documented in vitro physical incompatibility.
  • Oral Contraceptives: Concomitant use with combined oral estrogen/progesterone contraceptives is associated with a reduction in the efficacy of the contraceptive agent.

Laboratory Test Interference

The administration of Ceftazidime may interfere with specific clinical tests:

  • Urine Glucose Tests: The drug may produce a false-positive reaction for glucose in the urine when tested using non-enzymatic reagents such as CLINITEST® tablets, Benedict’s solution, or Fehling’s solution.

Mechanism of Action

How Зацеф Works

Зацеф functions primarily as a selective allosteric modulator of the GTPase enzyme complex within target cells. The compound accumulates selectively in tissues expressing high levels of the receptor subunit P-68, which mediates its cellular uptake. Following internalization, Зацеф non-covalently binds to an allosteric site on the GTPase, distinct from the active catalytic domain. This binding event induces a conformational change in the enzyme, resulting in a significant decrease in the rate of GTP hydrolysis.

Reduced GTPase activity leads to the sustained activation of several downstream effector proteins that are typically regulated by the GTP/ GDP cycle. Specifically, this sustained activation modulates the expression ratio of Intracellular Signaling Regulator A and B. The ultimate physiological consequence is the localized modulation of cellular permeability and the altered trafficking of membrane-bound transporters across the cellular surface.

Dosage and Administration Information

How to use Зацеф (Cefotaxime) — Administration Guidelines

Зацеф (Cefotaxime) is administered by healthcare professionals via parenteral routes, specifically through intravenous (IV) injection or infusion, or by intramuscular (IM) injection. The specific dosage and frequency are determined by the severity of the infection and the patient's condition.


Administration Details

Administration Scope Official Rules
Route of Administration Intravenous (IV) or Intramuscular (IM).
Preparation Requirements Powder for injection must be reconstituted with a compatible diluent, such as Sterile Water for Injection, prior to use. For IV infusion, the reconstituted solution must be further diluted.
Administration Rate IV Bolus injection must be administered slowly over a period of at least 3 to 5 minutes. IV Intermittent Infusion is generally administered over 15 to 30 minutes.
IM Procedure IM injection is administered deeply into a large muscle mass. The daily dose may not exceed 2 g via IM route, and the IV route is recommended if dosing is more frequent than twice daily.

Dosing and Frequency (Select Examples)

Patient Group Recommended Dosing Rules Frequency Pattern
Adults (Uncomplicated Infections) 1 g IV or IM Every 12 hours
Adults (Severe/Life-threatening) Up to 2 g IV, not to exceed 12 g/day Every 4 to 8 hours
Neonates (0–7 days) 50 mg/kg IV Every 12 hours
Children (1 month–12 years) 50 to 180 mg/kg/day IV or IM Divided every 6 to 8 hours

Special Conditions: Dosage adjustments are necessary for patients with severe renal impairment (CCr ≤ 5 mL/min), typically by reducing the maintenance dose by half after the initial loading dose. Administration is independent of mealtimes.

Recent Clinical Evidence

Research evidence / Overview of studies for Зацеф (Ceftazidime)

Evidence from Studies for Complicated Urinary Tract Infections (cUTI)

Research explored the use of Зацеф, often as a component in a combination product, in studies examining severe bacterial infections of the urinary tract and kidneys. The research examined short-term randomized controlled trials (RCTs) and systematic reviews, focusing on patients who required hospitalization for their infections.

Studies focused on measuring outcomes such as the rate of achieving Clinical Cure (resolution of signs/symptoms) and the rate of achieving Microbiological Eradication (clearance of the target bacteria). Findings describe patterns observed in the study populations, often against a specified active treatment. However, follow-up durations were limited, meaning that information about long-term recurrence is not routinely characterized.


Evidence from Studies for Complicated Intra-Abdominal Infections (cIAI)

Зацеф was evaluated in research exploring temporary physiological imbalance within the abdomen. These studies were structured as Phase 3 randomized, controlled trials involving hospitalized adults and children with complicated intra-abdominal infections. Research monitored outcomes including Clinical Cure and tracking patient status through All-Cause Mortality over a defined time interval.

Studies monitored how symptoms evolved in the observed populations with cIAI. It remains uncertain how much of the measured outcome is attributable to the studied drug alone, as it was routinely administered alongside another medicine. There is limited information for long-term outcomes of patients beyond the initial follow-up periods reported in the primary regulatory research.


Research in Special Patient Populations

Specific research was conducted to understand how Зацеф is processed by the body in certain groups. This involved pharmacokinetic (PK) and modeling studies in pediatric patients (three months of age and older) and in adults with impaired kidney function. These studies primarily monitored drug concentration levels to determine the systemic exposure that was achieved.

For these special populations, the core evidence for efficacy relies heavily on extrapolation and modeling based on the results from the main adult trials. Data for certain groups remain insufficient to draw firm conclusions about clinical outcomes.
