🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCefalexin is absorbed from the gastrointestinal tract after oral administration. Probenecid is also absorbed orally. Food may slightly delay the rate but not the extent of cefalexin absorption. Specific absorption percentages for this combination are not established from the available information.
DistributionCefalexin distributes into many body tissues and fluids, including the kidneys, lungs, skin, and soft tissues. Probenecid distributes in extracellular fluid and is highly bound to plasma proteins. Exact distribution volumes for this combination are not established from the available information.
Protein BindingCefalexin is approximately 10-15% bound to plasma proteins. Probenecid is highly protein-bound, approximately 85-95%. These values are for the individual ingredients and may not reflect the combination exactly.
MetabolismCefalexin is not significantly metabolized and is excreted largely unchanged. Probenecid is metabolized in the liver, mainly by glucuronidation, and its metabolites are excreted in urine. Specific metabolic data for the combination are not established from the available information.
Half-LifeThe elimination half-life of cefalexin is approximately 0.5 to 1.2 hours in adults with normal kidney function. Probenecid has a half-life of about 6 to 12 hours. When combined, probenecid prolongs cefalexin levels, but the exact half-life of the combination is not established from the available information.
ExcretionCefalexin is excreted primarily unchanged in the urine by glomerular filtration and tubular secretion. Probenecid is excreted in urine as metabolites and unchanged drug. Probenecid reduces the tubular secretion of cefalexin, which is the basis for their combined use.
BioavailabilityThe oral bioavailability of cefalexin is approximately 90% in fasting adults. The bioavailability of probenecid is not precisely established from the available information. The combination may alter the effective exposure to cefalexin.
Onset of ActionAntibacterial effects begin within a few hours after the first dose, but clinical improvement usually takes 24 to 48 hours. Probenecid's effect on cefalexin levels begins with the first dose.
Peak Plasma TimeCefalexin reaches peak plasma concentrations about 1 hour after oral administration. Probenecid peaks in about 2 to 4 hours. The peak time for the combination is not established from the available information.
Duration of ActionCefalexin's antibacterial effect is usually maintained for about 6 to 12 hours per dose, but probenecid may prolong effective levels. The exact duration for this combination is not established from the available information.

How It Works

Cefalexin is a first-generation cephalosporin antibiotic that kills bacteria by binding to penicillin-binding proteins and blocking the cross-linking of peptidoglycan in the bacterial cell wall. This weakens the cell wall and causes bacterial lysis. Probenecid does not kill bacteria; it inhibits the renal tubular secretion of cefalexin, which raises and prolongs cefalexin concentrations in the blood and tissues. Together, the combination aims to provide more sustained antibiotic exposure than cefalexin alone.

Mechanism Steps

1
Cefalexin binds penicillin-binding proteins: Cefalexin attaches to penicillin-binding proteins on the bacterial cell membrane, which are enzymes needed for cell wall construction.
2
Cell wall synthesis is blocked: By inhibiting these enzymes, cefalexin prevents the cross-linking of peptidoglycan strands, making the bacterial cell wall weak and unstable.
3
Bacterial lysis occurs: The weakened cell wall cannot maintain the internal pressure of the bacterium, so the cell bursts and dies.
4
Probenecid inhibits renal secretion: Probenecid blocks organic anion transporters in the kidney tubules that normally remove cefalexin from the blood into urine.
5
Cefalexin levels remain higher for longer: Because cefalexin is removed more slowly, its blood and tissue concentrations stay elevated, which can help the antibiotic work more effectively against susceptible bacteria.

Dosage Information

Adult DosageThe dose of this medicine is individualized by a qualified clinician based on the type and severity of infection, kidney function, and other factors. A common adult dose for cefalexin is 250 mg to 500 mg every 6 to 12 hours, but the addition of probenecid changes the dosing schedule. Do not self-medicate. Follow your doctor's prescription exactly, and complete the full course even if you feel better.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may have reduced kidney function and are more sensitive to the effects of this medicine. Dose adjustment may be needed based on kidney function. Consult your doctor for individualized dosing.
Renal ImpairmentDose adjustment is required in patients with kidney impairment. Cefalexin is removed by the kidneys, and probenecid affects kidney function. Your doctor may reduce the dose or extend the dosing interval based on creatinine clearance. Do not use without medical advice if you have kidney disease.
Hepatic ImpairmentNo specific dose adjustment is established for liver impairment, but caution is advised. Probenecid is metabolized in the liver, so monitor liver function if you have liver disease. Consult your doctor for individualized dosing.
Maximum Daily DoseThe maximum daily dose must be determined by a qualified clinician based on the indication and patient factors. Do not exceed the prescribed dose.
