Flucloxin
Flucloxin Uses, Dosage, Side Effects, Food Interaction and all others data.
Flucloxin inhibits the 3rd and last step of bacterial cell wall synthesis by binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall. It is active against penicillinase-producing and non-penicillinase-producing staphylococci.
Flucloxin is isoxazolyl penicillin which combined the properties of resistance to hydrolysis by penicillinase, gastric acid stability and activity against gram-positive bacteria. Flucloxin is a bactericidal antibiotic that is particularly useful against penicillinase-producing staphylococci. Flucloxin kills bacterial cellwall, thus interfering with peptidoglycan synthesis. Peptidoglycan is a heteropolymeric structure that provides the cell wall with its mechanical stability. The final stage of peptidoglycan synthesis involves the completion of the cross-linking with the terminal glycine residue of the pentaglycin bridge linking to the fourth residue of the pentapeptide (D-alanine). The transpeptidase enzyme that performs this step is inhibited by Flucloxin. As a result the bacterial cellwall is weakened, the cell swells and then ruptures. Flucloxin resists the action of bacterial penicillinase probably because of the steric hindrance induced by the acyl side chain which prevents the opening of the β- lactam ring.
Flucloxin is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The name "penicillin" can either refer to several variants of penicillin available, or to the group of antibiotics derived from the penicillins. Flucloxin has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of Flucloxin results from the inhibition of cell wall synthesis and is mediated through flucloxacillin binding to penicillin binding proteins (PBPs). Flucloxin is stable against hydrolysis by a variety of beta-lactamases, including penicillinases, and cephalosporinases and extended spectrum beta-lactamases.

Uses
Flucloxin is used for the treatment of infections due to Gram-positive organisms, including infections caused by β-lactamase producing staphylococci.
Skin and Soft Tissue Infections: Boils, abscesses, carbuncles, furunculosis,infected wounds, infected burns, protection of skin grafts, otitis media and externa, impetigo.
Infected Skin Conditions: Ulcer, eczema and acne.
Respiratory Tract Infections: Pneumonia, lung abscess, empyema, sinusitis,pharyngitis, tonsillitis, quinsy.
Other infections caused by Flucloxin-sensitive organisms such as osteomyelitis, enteritis, endocarditis, urinary tract infection, meningitis, septicaemia.
Flucloxin is also used for use as a prophylactic agent during major surgical procedures where appropriate, for example, cardiothoracic and orthopaedic surgery
Flucloxin is also used to associated treatment for these conditions: Susceptible infections
How Flucloxin works
By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, flucloxacillin inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that flucloxacillin interferes with an autolysin inhibitor.
Dosage
Flucloxin dosage
Oral administration:
Adult or Elderly:
- Usual dosage: 250 mg four times daily. In severe infections, dosage should be doubled.
- In osteomyelitis and endocarditis: up to 8 gm daily, in divided doses 6 to 8 hourly.
- In case of secondary bacterial infection in chicken pox: Flucloxin 500 mg six hourly should be prescribed.
Children:
- Usual dosage: 2-10 years: half of the adult dose. Under 2 years: quarter of the adult dose.
Parenteral administration:
Adult or Elderly:
- Intramuscular Injection: 250 mg four times daily.
- Intravenous Injection: 250 mg-1 g four times daily by slow injection over 3 to 4 minutes or by intravenous infusion.
- All systemic doses may be doubled in severe infections: doses up to 8 g daily have been suggested for endocarditis or osteomyelitis.
Children:
- Usual dosage: 2-10 years : half of the adult dose. Under 2 years : quarter of the adult dose.
Doses should be administered half an hour before meals.
Flucloxin has been used in other routes in conjunction with systemic therapy. It has been administered in a dose of 250 mg to 500 mg daily by intraarticular injection, dissolved if necessary in a 0.5% solution of lignocaine hydrochloride, and by intrapleural injection in a dose of 250 mg daily. Using powder for injection, 125 mg-250 mg has been dissolved in 3 ml of sterile water and inhaled by nebuliser four times daily.
Side Effects
There have been some common side effects of GIT such as nausea, vomiting, diarrhoea, dyspepsia and other minor gastrointestinal disturbances. Besides these rashes, urticaria, purpura, fever, interstitial nephritis, hepatitis and cholestatic jaundice have been reported
Precaution
Patient with spirochaete infections (e.g. syphilis, leptospirosis), history of hypersensitivity to β-lactam antibiotics. Newborn infants. Hepatic or renal impairment. Pregnancy and lactation.
Interaction
The administration of probenecid with Flucloxin results in higher serum peak concentrations and prolongs the time that therapeutic concentrations of Flucloxin are achieved in serum. Physical incompatibility and/or loss of activity of Flucloxin in solution has been reported when given with gentamycin sulphate, streptomycin sulphate, vitamin mixtures. Flucloxin should not be added to intravenous lipids, blood products and protein hydrolysates or other proteinaceous fluids.
Food Interaction
- Take on an empty stomach.
Elimination Route
Bioavailability is 50–70% following oral administration.
Half Life
0.75–1 hour
Pregnancy & Breastfeeding use
The use of Flucloxin in pregnancy should be reserved for cases considered essential by the clinician. Use of the drug in the second and third trimesters may result in the sensitisation of the fetus. During lactation, trace quantities of penicillins can be detected in breast milk.
Contraindication
Flucloxin is contraindicated for those who have hypersensitivity to penicillins.
Special Warning
Dose adjustment in renal impairment : As common with other penicillins, Flucloxin usage in patients with renal impairment does not usually require dosage reduction. However, in the presence of severe renal failure (creatinine clearance < 10 ml/min) a reduction in dose or an extension of dose interval should be considered. Flucloxin is not significantly removed by dialysis and hence no supplementary dosages need to be administered either during or at the end of the dialysis period.
Acute Overdose
Symptoms: Neurotoxicity (e.g. convulsions, encephalopathy), GI effects (e.g. nausea, vomiting, diarrhoea), blood disorders (e.g. neutropenia, haemolytic anaemia, prolongation of bleeding time, defective platelet function), electrolyte disturbances.
Management: Symptomatic treatment.
Storage Condition
Store below 25° C. Reconstituted solution: Store between 2-8°C.
