🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is administered by injection, so absorption is not applicable. It is directly delivered into the bloodstream or muscle tissue.
DistributionCeftriaxone is widely distributed into body tissues and fluids, including cerebrospinal fluid, bile, and synovial fluid. It crosses the placenta and is excreted in breast milk. Sulbactam also distributes widely, but its penetration into cerebrospinal fluid is limited.
Protein BindingCeftriaxone is highly protein-bound (approximately 85-95%), primarily to albumin. Sulbactam is approximately 38% protein-bound.
MetabolismCeftriaxone is not significantly metabolized and is excreted largely unchanged. Sulbactam is partially metabolized in the liver.
Half-LifeThe elimination half-life of ceftriaxone is approximately 6-9 hours in healthy adults, and it is prolonged in patients with renal or hepatic impairment. The half-life of sulbactam is approximately 1-1.5 hours.
ExcretionCeftriaxone is excreted primarily unchanged in the urine (about 50-60%) and in bile (about 40-50%). Sulbactam is excreted mainly in the urine (about 70-80%) as unchanged drug.
BioavailabilityNot applicable for injectable administration; bioavailability is 100% when given intravenously.
Onset of ActionThe onset of action is rapid, typically within 30 minutes to 1 hour after intravenous administration.
Peak Plasma TimePeak plasma concentrations are achieved immediately after intravenous injection and within 1-2 hours after intramuscular injection.
Duration of ActionThe antibacterial effect lasts for approximately 12-24 hours, depending on the dose and the susceptibility of the organism.

How It Works

This medicine combines two active ingredients. Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins, leading to weakened cell walls and bacterial death. Sulbactam is a beta-lactamase inhibitor that irreversibly binds to certain beta-lactamase enzymes produced by bacteria, preventing them from destroying ceftriaxone. This combination extends the spectrum of ceftriaxone against bacteria that produce beta-lactamases, making the combination effective against a broader range of pathogens.

Mechanism Steps

1
Ceftriaxone binds to penicillin-binding proteins: Ceftriaxone attaches to specific proteins in the bacterial cell wall, blocking the cross-linking of peptidoglycan strands.
2
Inhibition of cell wall synthesis: This blockade prevents the bacteria from building a strong cell wall, leading to cell lysis and death.
3
Sulbactam inhibits beta-lactamase enzymes: Sulbactam binds irreversibly to beta-lactamase enzymes, preventing them from breaking down ceftriaxone.
4
Enhanced antibacterial spectrum: By protecting ceftriaxone, sulbactam allows the antibiotic to act against bacteria that would otherwise be resistant.

Dosage Information

Adult DosageThe usual adult dose of this medicine is 1.5 g (500 mg ceftriaxone + 250 mg sulbactam) to 3 g (1 g ceftriaxone + 500 mg sulbactam) administered intravenously or intramuscularly every 12 hours. For severe infections, higher doses may be used. The dose must be individualized by a qualified clinician based on the indication, severity of infection, age, weight, renal and hepatic function. Treatment duration varies from 5 to 14 days depending on the infection.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing.
Elderly DosageElderly patients may have reduced kidney function and may require dose adjustment. Monitor renal function closely. Dose must be individualized by a qualified clinician.
Renal ImpairmentIn patients with renal impairment (creatinine clearance < 30 mL/min), dose adjustment may be necessary. Ceftriaxone does not require adjustment in mild to moderate renal impairment, but sulbactam may accumulate. Consult a clinician for individualized dosing.
Hepatic ImpairmentIn patients with severe hepatic impairment, dose adjustment may be needed. Monitor liver function. Consult a clinician for individualized dosing.
Maximum Daily DoseThe maximum recommended daily dose is 4 g of ceftriaxone and 1 g of sulbactam, but this must be determined by a clinician based on the patient's condition.
