Cefuroxime axetil is an oral prodrug of cefuroxime, a second-generation cephalosporin antibiotic. It is used to treat a variety of bacterial infections. After oral administration, cefuroxime axetil is rapidly hydrolyzed in the intestinal wall to release active cefuroxime, which then exerts its antibacterial effect.
How does cefuroxime axetil work?
Cefuroxime axetil works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs), which are essential enzymes involved in the final stages of peptidoglycan synthesis. This disruption leads to weakened cell walls and eventual bacterial lysis [1].
What types of infections can cefuroxime axetil treat?
Cefuroxime axetil is effective against a range of Gram-positive and Gram-negative bacteria. It is indicated for the treatment of infections such as acute exacerbations of chronic bronchitis, acute bacterial otitis media, pharyngitis/tonsillitis, and uncomplicated urinary tract infections [2]. It is also used for the treatment of Lyme disease, specifically early disseminated disease [3].
What is the typical dosage and administration?
Dosage and duration of treatment with cefuroxime axetil vary depending on the type and severity of the infection, as well as the patient's age and kidney function. It is typically administered orally, with or without food [2]. For example, a common dose for acute exacerbations of chronic bronchitis is 250 mg twice daily for 10 days [2].
What are the potential side effects of cefuroxime axetil?
Common side effects may include nausea, vomiting, diarrhea, and headache. Less common side effects can include dizziness, yeast infections, and changes in liver enzymes [2]. Allergic reactions, including rash and anaphylaxis, are also possible, though rare [2].
Are there any contraindications for cefuroxime axetil?
Cefuroxime axetil is contraindicated in patients with a known hypersensitivity to cefuroxime, other cephalosporins, or any component of the formulation [2].
What is the difference between cefuroxime and cefuroxime axetil?
Cefuroxime axetil is an oral prodrug that is converted to the active drug, cefuroxime, in the body. Cefuroxime itself is typically administered intravenously or intramuscularly. The axetil ester form enhances oral bioavailability [1].
When does cefuroxime axetil patent protection expire?
Information regarding specific patent expiry dates for cefuroxime axetil products can be found on resources like DrugPatentWatch.com. Patents for older drugs like cefuroxime axetil often expire many years after their initial approval, allowing for the development of generic versions [4]. For instance, the original patent for cefuroxime axetil has long expired, facilitating the availability of generic formulations.
Who manufactures cefuroxime axetil?
Multiple pharmaceutical companies manufacture both the branded and generic versions of cefuroxime axetil. The specific manufacturer will depend on the region and whether a branded or generic product is being dispensed.
Can other antibiotics be used instead of cefuroxime axetil?
Treatment decisions depend on the specific infection, local resistance patterns, and individual patient factors. Other antibiotics may be used to treat similar infections, and the choice is made by a healthcare professional [2].
