🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCefixime is absorbed from the gastrointestinal tract, with bioavailability estimated at 40-50% for the suspension and 50% for tablets. Ofloxacin is rapidly and almost completely absorbed, with bioavailability approaching 98%. Food may slightly delay absorption but does not significantly affect the extent.
DistributionCefixime distributes well into tissues and body fluids, including bile, sputum, and urine. Ofloxacin distributes widely into body tissues and fluids, including lung, skin, prostate, and cerebrospinal fluid (especially when inflamed). Both drugs have moderate protein binding.
Protein BindingCefixime is about 65-70% protein-bound. Ofloxacin is approximately 20-32% protein-bound.
MetabolismCefixime is not significantly metabolized and is excreted largely unchanged. Ofloxacin undergoes limited metabolism, with less than 10% metabolized in the liver.
Half-LifeThe elimination half-life of cefixime is approximately 3-4 hours in healthy adults. The elimination half-life of ofloxacin is approximately 4-5 hours, prolonged in renal impairment.
ExcretionCefixime is primarily excreted unchanged in the urine (about 50% of absorbed dose) and bile. Ofloxacin is excreted mainly unchanged in the urine (70-80%) and feces (about 20%).
BioavailabilityCefixime bioavailability is about 40-50%. Ofloxacin bioavailability is approximately 98%.
Onset of ActionOnset of action is typically within 1-2 hours after oral administration, corresponding to peak plasma concentrations.
Peak Plasma TimeCefixime peak plasma concentration occurs 2-4 hours after oral administration. Ofloxacin peak plasma concentration occurs 1-2 hours after oral administration.
Duration of ActionThe duration of action is generally 12-24 hours, depending on the dosing interval. Both drugs require twice-daily dosing for most indications.

How It Works

This medicine combines two antibiotics with distinct mechanisms. Cefixime, a cephalosporin, binds to penicillin-binding proteins (PBPs) and inhibits bacterial cell wall synthesis, leading to cell lysis and death. Ofloxacin, a fluoroquinolone, inhibits DNA gyrase and topoisomerase IV, enzymes required for DNA replication, transcription, repair, and recombination, thereby causing bacterial cell death. The combination provides a broader spectrum and may be synergistic against certain pathogens.

Mechanism Steps

1
Cefixime binds to PBPs: Cefixime binds to penicillin-binding proteins on the bacterial cell membrane, inhibiting the cross-linking of peptidoglycan chains in the cell wall.
2
Cell wall lysis: Inhibition of cell wall synthesis leads to weakening of the bacterial cell wall and eventual lysis, especially in rapidly dividing bacteria.
3
Ofloxacin inhibits DNA gyrase: Ofloxacin binds to DNA gyrase (topoisomerase II) and topoisomerase IV, blocking the supercoiling of DNA and preventing replication.
4
Bacterial DNA damage: The inhibition of these enzymes leads to double-strand breaks in bacterial DNA, halting replication and causing cell death.

💡 How to Take cfx o 100mg/100mg tablet

Dosage Information

Adult DosageThe usual adult dose of this combination is one tablet (Cefixime 100 mg + Ofloxacin 100 mg) taken orally twice daily, or as prescribed by your doctor. The duration of treatment depends on the type and severity of infection, 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.
Elderly DosageElderly patients may require dose adjustment based on renal function. Use with caution due to increased risk of tendon rupture, CNS effects, and renal impairment. Dose must be individualized by a qualified clinician.
Renal ImpairmentDose adjustment is required in patients with renal impairment. For creatinine clearance (CrCl) 20-40 mL/min, reduce dose or increase dosing interval. For CrCl <20 mL/min, further reduce dose. Consult a clinician for specific dosing.
Hepatic ImpairmentNo specific dose adjustment is established for hepatic impairment. Use with caution and monitor liver function.
Maximum Daily DoseThe maximum recommended daily dose is 200 mg of cefixime and 400 mg of ofloxacin, but this may vary based on indication and renal function. Always follow your doctor's prescription.
