🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAmoxycillin and dicloxacillin are both absorbed from the gastrointestinal tract after oral administration. Amoxycillin is rapidly absorbed, with peak plasma concentrations occurring 1 to 2 hours after ingestion. Dicloxacillin is also absorbed but may have a slightly slower absorption rate. Food can affect the absorption of dicloxacillin; taking it with food may reduce absorption. However, this combination is often taken with food to minimize stomach upset. The exact bioavailability of the combination product is not established from the available information.
DistributionBoth amoxycillin and dicloxacillin distribute widely into body tissues and fluids, including skin, soft tissues, and bone. Amoxycillin achieves good concentrations in respiratory secretions, middle ear fluid, and urine. Dicloxacillin is highly protein-bound and penetrates well into skin and soft tissues, making it suitable for skin infections. The volume of distribution for each component is not established from the available information.
Protein BindingAmoxycillin is approximately 17-20% protein-bound. Dicloxacillin is highly protein-bound, approximately 95-99%. The protein binding of the combination product is not established from the available information.
MetabolismAmoxycillin is partially metabolized in the liver to inactive metabolites, but a significant portion is excreted unchanged. Dicloxacillin is metabolized in the liver to inactive metabolites. The exact metabolic pathways and extent of metabolism for the combination product are not established from the available information.
Half-LifeThe elimination half-life of amoxycillin is approximately 1 to 1.5 hours in patients with normal renal function. The elimination half-life of dicloxacillin is approximately 0.5 to 0.9 hours. The half-life of the combination product is not established from the available information.
ExcretionAmoxycillin is primarily excreted unchanged in the urine via glomerular filtration and tubular secretion. Dicloxacillin is excreted in the urine and bile, with a significant portion excreted in the feces. The exact excretion profile of the combination product is not established from the available information.
BioavailabilityThe bioavailability of amoxycillin is approximately 80-90% when taken orally. The bioavailability of dicloxacillin is approximately 35-76% and is reduced when taken with food. The bioavailability of the combination product is not established from the available information.
Onset of ActionThe onset of action for this medicine is typically within 1 to 2 hours after oral administration, corresponding to the absorption and peak plasma concentrations of the antibiotics. However, clinical improvement of symptoms may take 24 to 48 hours.
Peak Plasma TimePeak plasma concentrations for amoxycillin occur approximately 1 to 2 hours after oral administration. For dicloxacillin, peak plasma concentrations occur approximately 0.5 to 2 hours after oral administration. The peak plasma time for the combination product is not established from the available information.
Duration of ActionThe duration of action for this medicine depends on the dosing frequency. With typical dosing every 6 to 8 hours, the antibacterial effect is maintained throughout the dosing interval. The exact duration of action for the combination product is not established from the available information.

How It Works

This medicine contains two penicillin antibiotics that inhibit bacterial cell wall synthesis. Amoxycillin and dicloxacillin both bind to penicillin-binding proteins (PBPs) in the bacterial cell membrane, interfering with the cross-linking of peptidoglycan chains that form the bacterial cell wall. This leads to weakening of the cell wall and ultimately bacterial lysis and death. Dicloxacillin is resistant to degradation by penicillinase enzymes produced by certain bacteria, such as Staphylococcus aureus, allowing it to remain active against these organisms. Amoxycillin has a broader spectrum but is susceptible to penicillinase. The combination provides coverage against both penicillinase-producing and non-producing bacteria.

Mechanism Steps

1
Binding to penicillin-binding proteins: Amoxycillin and dicloxacillin bind to specific penicillin-binding proteins (PBPs) located in the bacterial cell membrane.
2
Inhibition of cell wall cross-linking: This binding inhibits the transpeptidase enzyme responsible for cross-linking peptidoglycan chains, which are essential for cell wall integrity.
3
Activation of autolysins: The disruption of cell wall synthesis leads to activation of bacterial autolytic enzymes that further degrade the cell wall.
4
Bacterial lysis and death: The weakened cell wall cannot withstand osmotic pressure, causing the bacterium to lyse and die.

Dosage Information

Adult DosageThe usual adult dose of this medicine is one capsule (250 mg amoxycillin + 250 mg dicloxacillin) taken orally every 6 to 8 hours, depending on the severity of the infection. For skin and soft tissue infections, the dose may be 250-500 mg every 6 hours. The duration of therapy is typically 7 to 14 days, but may vary. 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 kidney function and may require dose adjustment. Dose must be individualized by a qualified clinician based on renal function.
Renal ImpairmentIn patients with renal impairment, dose adjustment may be necessary. For amoxycillin, the dosing interval may be extended in patients with creatinine clearance less than 30 mL/min. Dicloxacillin is primarily metabolized in the liver, so renal adjustment may not be needed, but caution is advised. Consult a clinician for individualized dosing.
Hepatic ImpairmentIn patients with hepatic impairment, no specific dose adjustment is established, but monitoring for signs of toxicity is advised. Consult a clinician for individualized dosing.
Maximum Daily DoseThe maximum daily dose is not established from the available information. Doses should not exceed the recommended range without medical supervision.
