🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCefixime is absorbed from the gastrointestinal tract after oral administration. The bioavailability of the oral suspension is approximately 40-50%.
DistributionCefixime is distributed widely into body tissues and fluids, including the respiratory tract, urine, and bile. It does not penetrate the cerebrospinal fluid well in the absence of inflammation.
Protein BindingCefixime is approximately 65% bound to plasma proteins, primarily albumin.
MetabolismCefixime is not significantly metabolized in the body. It is excreted largely unchanged.
Half-LifeThe elimination half-life of cefixime is approximately 3 to 4 hours in healthy adults with normal renal function.
ExcretionCefixime is excreted primarily unchanged in the urine, with about 50% of an oral dose recovered in the urine within 24 hours.
BioavailabilityThe absolute bioavailability of cefixime oral suspension is approximately 40-50%.
Onset of ActionThe onset of action is typically within 1 to 2 hours after oral administration, but clinical improvement may take 24 to 48 hours.
Peak Plasma TimePeak plasma concentrations are achieved approximately 2 to 4 hours after oral administration.
Duration of ActionThe duration of action is typically 12 to 24 hours, depending on the dose and renal function.

How It Works

Cefixime is a third-generation cephalosporin antibiotic that works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) located inside the bacterial cell wall, preventing the cross-linking of peptidoglycan strands. This leads to a weakened cell wall and ultimately bacterial cell death. Cefixime is bactericidal and has a broad spectrum of activity against many gram-positive and gram-negative bacteria.

Mechanism Steps

1
Binding to penicillin-binding proteins: Cefixime binds to specific penicillin-binding proteins (PBPs) on the bacterial cell membrane.
2
Inhibition of cell wall synthesis: This binding inhibits the transpeptidation reaction required for peptidoglycan cross-linking, weakening the cell wall.
3
Bacterial cell lysis: The weakened cell wall leads to osmotic instability and ultimately bacterial cell death.

Dosage Information

Adult DosageThe usual adult dose of cefixime is 400 mg per day, which can be taken as a single daily dose or divided into two doses of 200 mg every 12 hours. For uncomplicated urinary tract infections, a dose of 400 mg once daily is often used. For more severe infections, the dose may be increased to 400 mg every 12 hours. The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosageThe usual pediatric dose of cefixime is 8 mg/kg/day, which can be taken as a single daily dose or divided into two doses of 4 mg/kg every 12 hours. For otitis media, the dose may be 8 mg/kg/day. The maximum pediatric dose should not exceed 400 mg per day. Pediatric dosing is not established from available information for infants under 6 months of age. Consult a pediatrician.
Elderly DosageElderly patients may have reduced renal function, so the dose should be adjusted based on creatinine clearance. The usual adult dose can be used if renal function is normal. Dose must be individualized by a qualified clinician.
Renal ImpairmentIn patients with renal impairment, the dose of cefixime should be adjusted. For creatinine clearance (CrCl) 20-60 mL/min, the dose should be reduced to 300 mg once daily. For CrCl less than 20 mL/min, the dose should be reduced to 200 mg once daily. Dose must be individualized by a qualified clinician.
Hepatic ImpairmentNo specific dosage adjustment is required for hepatic impairment, as cefixime is not significantly metabolized by the liver. However, use with caution and monitor liver function.
Maximum Daily DoseThe maximum recommended daily dose of cefixime is 400 mg for adults and 400 mg for children, regardless of formulation.
