🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAmpicillin is absorbed from the gastrointestinal tract after oral administration. Sulbactam is also absorbed orally. Food may slightly delay absorption but does not significantly reduce the overall extent. The bioavailability of ampicillin is approximately 30-55% when taken orally.
DistributionBoth ampicillin and sulbactam distribute widely into body tissues and fluids, including pleural fluid, peritoneal fluid, and synovial fluid. They cross the placenta and are excreted in breast milk in small amounts. Protein binding is relatively low.
Protein BindingAmpicillin is approximately 15-25% bound to plasma proteins. Sulbactam is about 38% bound to plasma proteins.
MetabolismAmpicillin is partially metabolized in the liver to inactive metabolites. Sulbactam undergoes limited metabolism and is primarily excreted unchanged.
Half-LifeThe elimination half-life of ampicillin is approximately 1 to 1.5 hours in adults with normal renal function. Sulbactam has a half-life of about 1 hour. These half-lives are prolonged in patients with renal impairment.
ExcretionAmpicillin and sulbactam are primarily excreted unchanged in the urine. Approximately 60-70% of ampicillin and 70-80% of sulbactam are recovered in urine within 8 hours after oral administration.
BioavailabilityThe oral bioavailability of ampicillin is approximately 30-55%. Sulbactam's oral bioavailability is about 60-70%.
Onset of ActionThe onset of antibacterial action begins within 1-2 hours after oral administration, but clinical improvement may take 24-48 hours.
Peak Plasma TimePeak plasma concentrations of ampicillin and sulbactam are reached approximately 1-2 hours after oral administration.
Duration of ActionThe antibacterial effect typically lasts for about 6-8 hours, depending on the dose and renal function.

How It Works

This medicine combines ampicillin, a broad-spectrum penicillin antibiotic, with sulbactam, a beta-lactamase inhibitor. Ampicillin works by binding to penicillin-binding proteins (PBPs) on the bacterial cell wall, inhibiting the final transpeptidation step of peptidoglycan synthesis. This leads to weakened cell walls and bacterial lysis. Sulbactam irreversibly inhibits certain beta-lactamase enzymes produced by bacteria, preventing them from hydrolyzing ampicillin. This dual action allows ampicillin to remain active against beta-lactamase-producing bacteria that would otherwise be resistant.

Mechanism Steps

1
Binding to penicillin-binding proteins: Ampicillin binds to specific penicillin-binding proteins on the bacterial cell wall, inhibiting cell wall synthesis.
2
Inhibition of beta-lactamase enzymes: Sulbactam irreversibly binds to beta-lactamase enzymes, preventing them from breaking down ampicillin.
3
Bacterial cell lysis: With cell wall synthesis inhibited and beta-lactamases blocked, bacteria undergo lysis and die.

Dosage Information

Adult DosageThe usual adult dose of this medicine is one 375 mg tablet taken orally every 8 to 12 hours, depending on the severity and type of infection. For more severe infections, a higher dose or more frequent administration may be prescribed. The duration of treatment varies by indication, typically 5 to 14 days. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-adjust the dose.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children.
Elderly DosageElderly patients may have reduced renal function, which can increase the risk of side effects. Dose adjustment may be necessary based on renal function. Consult a doctor for appropriate dosing.
Renal ImpairmentIn patients with renal impairment, dose adjustment is required. For creatinine clearance between 15-29 mL/min, the dose may be reduced or the interval extended. For creatinine clearance less than 15 mL/min, the drug should be used with caution and dose adjusted accordingly. Consult a doctor for specific recommendations.
Hepatic ImpairmentNo specific dose adjustment is established for hepatic impairment, but caution is advised. Monitor liver function tests periodically.
Maximum Daily DoseThe maximum recommended daily dose is not established from available information. Doses should not exceed those prescribed by a qualified clinician.
