👨‍⚕️ Doctor's Practical Tips

Evidence-based practical advice from experienced clinicians

1
Always verify the patient's allergy history before administering this medicine, especially to penicillins and cephalosporins.
2
Adjust the dose based on creatinine clearance in patients with renal impairment to avoid seizures and other toxicities.
3
Monitor for signs of superinfection, such as oral thrush or C. difficile diarrhea, during prolonged therapy.
4
When treating Pseudomonas infections, consider combination therapy with an aminoglycoside for synergy, but monitor renal function.
5
Ensure the full prescribed course is completed to prevent antibiotic resistance.
6
Educate patients about the importance of reporting any signs of allergic reactions immediately.

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAztreonam is not absorbed orally and must be administered parenterally. Following intramuscular injection, it is rapidly and completely absorbed. Following intravenous infusion, it is completely bioavailable.
DistributionAztreonam distributes widely into body tissues and fluids, including pleural fluid, synovial fluid, peritoneal fluid, and blister fluid. It crosses the placenta and is excreted in breast milk in low concentrations. It does not penetrate the cerebrospinal fluid well unless the meninges are inflamed.
Protein BindingApproximately 56% bound to serum proteins.
MetabolismAztreonam is minimally metabolized in the liver. The majority of the drug is excreted unchanged.
Half-LifeThe elimination half-life is approximately 1.5 to 2 hours in adults with normal renal function. It is prolonged in patients with renal impairment.
ExcretionAztreonam is primarily excreted unchanged in the urine (approximately 60-70% of a dose) via glomerular filtration and tubular secretion. A small amount is excreted in feces.
Bioavailability100% for intravenous administration; approximately 100% for intramuscular administration.
Onset of ActionRapid; bacterial killing begins shortly after the drug reaches therapeutic concentrations, typically within 1-2 hours after administration.
Peak Plasma TimeApproximately 1 hour after intramuscular injection; immediately after intravenous infusion.
Duration of ActionThe duration of action depends on the dosing interval; therapeutic levels are maintained for approximately 6-8 hours after a standard dose, requiring dosing every 6-8 hours.

How It Works

Aztreonam exerts its bactericidal effect by binding with high affinity to penicillin-binding protein 3 (PBP3) in susceptible Gram-negative bacteria. This binding inhibits the transpeptidation reaction necessary for cross-linking peptidoglycan chains in the bacterial cell wall. As a result, the cell wall becomes weakened and osmotically unstable, leading to bacterial lysis and death. Because aztreonam has a monobactam structure, it is stable against many beta-lactamases produced by Gram-negative bacteria, but it is hydrolyzed by extended-spectrum beta-lactamases (ESBLs) and carbapenemases. It has no activity against Gram-positive bacteria or anaerobes due to poor binding to their PBPs.

Mechanism Steps

1
Binding to PBP3: Aztreonam diffuses through the outer membrane of Gram-negative bacteria and binds covalently to penicillin-binding protein 3 (PBP3).
2
Inhibition of cell wall synthesis: This binding inhibits the transpeptidase activity of PBP3, preventing the cross-linking of peptidoglycan strands in the bacterial cell wall.
3
Cell wall weakening and lysis: The weakened cell wall cannot withstand osmotic pressure, leading to cell lysis and bacterial death.

💡 How to Take ztokem injection

Strength: Aztreonam 2000 mg (2 g) powder for injection.

1This medicine is administered by a healthcare professional in a hospital or clinic setting.
2It is given as an intravenous (IV) injection or infusion, or as an intramuscular (IM) injection.
3The dose and frequency will be determined by your doctor based on your condition and kidney function.
4Do not attempt to self-administer this medicine.
5Follow your doctor's instructions for the duration of therapy.

Dosage Information

Adult DosageThe usual adult dose of this medicine ranges from 1 g to 2 g every 6 to 12 hours, depending on the severity and type of infection. For severe infections, doses up to 2 g every 6 to 8 hours may be used. The maximum recommended daily dose is 8 g. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may have reduced renal function; dose should be adjusted based on creatinine clearance. No specific dose adjustments are recommended other than those based on renal function.
Renal ImpairmentIn patients with renal impairment, the dose and/or dosing interval should be adjusted. For creatinine clearance 10-30 mL/min, the usual dose is 1-2 g initially, followed by half the usual dose at the usual interval. For creatinine clearance less than 10 mL/min, the initial dose is 1-2 g, followed by half the usual dose every 12 hours. Patients on hemodialysis should receive an additional dose after dialysis.
Hepatic ImpairmentNo specific dose adjustment is required for hepatic impairment alone, as aztreonam is minimally metabolized by the liver.
Maximum Daily DoseThe maximum recommended daily dose is 8 g.

Additional Safety Advice

General Safety

This medicine must be administered by a qualified healthcare professional. Inform your doctor about all your medical conditions, especially kidney disease, liver disease, or allergies to antibiotics. Do not use this medicine if you are allergic to aztreonam or have had a severe allergic reaction to any antibiotic. Tell your doctor about all medications you are taking, including prescription and over-the-counter drugs, vitamins, and herbal supplements. Avoid alcohol during treatment as it may worsen side effects. If you are pregnant or breastfeeding, consult your doctor before receiving this medicine.
