Mechanism of Action of Roxicef
How does Cefuroxime work to cure or prevent bacteria infections?
Cefuroxime axetil undergoes hydrolysis by esterase enzymes to the active antibiotic, cefuroxime. Remember that Cefuroxime axetil is a prodrug.
Cefuroxime inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). This results in the interruption of cell wall (peptidoglycan) biosynthesis, which leads to bacterial cell lysis and death.
When not to use Roxicef
Do not use Cefuroxime if you are allergic to it or to any of cephalosporins and penicillin antibiotics.
Can Roxicef be used in pregnancy?
Cefuroxime is considered safe in pregnancy.
Pregnancy category B.
Can Roxicef be used while breastfeeding
It enters breast milk, use not advised.
- Food increases Cefuroxime absorption, so take it with food.
- Cefuroxime may affect the gut flora, leading to lower oestrogen reabsorption and reduced efficacy of combined oral contraceptives.
- Concomitant use of probenicid is not recommended. This is because administration of probenecid with Cefuroxime prolongs the excretion of cefuroxime and produces an elevated peak serum level.
- Treatments with cephalosporins should be carried out with caution on patients who are taking strong-acting diuretics (such as furosemide) or potential nephrotoxic preparations (such as aminoglycoside antibiotics), since impairment of renal function through such combinations cannot be ruled out.
- Determination of blood/plasma glucose levels: A false-positive reaction for glucose in the urine may occur with copper reduction tests (e.g., Benedict’s or Fehling’s solution). As a false-negative result may occur in the ferricyanide test, it is recommended that either the glucose oxidase or hexokinase method be used to determine blood/plasma glucose levels in patients receiving cefuroxime axetil.
- Concomitant use with oral anticoagulants may give rise to increased international normalised ratio (INR).
- Drugs that reduce gastric acidity may result in a lower bioavailability of Cefuroxime compared with administration in the fasting state.
