🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Flucloxacillin sodium is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding inhibits the transpeptidation reaction, preventing cross-linking of peptidoglycan chains, which is essential for cell wall integrity. The result is bacterial cell lysis and death, particularly in actively dividing bacteria. Flucloxacillin is resistant to hydrolysis by penicillinase enzymes produced by certain staphylococci, making it effective against penicillinase-producing Staphylococcus aureus.
Mechanism Steps
💡 How to Take flulen injection
Strength: Injection: 1000 mg
Dosage Information
| Adult Dosage | The usual adult dose is 250 mg to 2 g every 4 to 6 hours by intramuscular or intravenous injection, depending on the severity and type of infection. For severe infections, higher doses may be used. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may have reduced renal function; dose adjustment may be necessary based on creatinine clearance. Use with caution and monitor renal function. |
| Renal Impairment | In patients with renal impairment, dose reduction or increased dosing interval may be required. For creatinine clearance less than 10 mL/min, the dose should be reduced. Consult a clinician for specific adjustments. |
| Hepatic Impairment | No specific dose adjustment is established for hepatic impairment, but use with caution and monitor liver function. |
| Maximum Daily Dose | The maximum daily dose is not established from available information. Doses up to 12 g per day have been used in severe infections under close medical supervision. |
