Cefuroxime axetil is an antibiotic used to treat a variety of bacterial infections [1]. It is a prodrug of cefuroxime, a second-generation cephalosporin, meaning it is converted into its active form, cefuroxime, after administration [2].
What bacterial infections does cefuroxime axetil treat?
Cefuroxime axetil is effective against a range of bacterial pathogens. It is commonly prescribed for infections of the respiratory tract, such as acute bronchitis and exacerbations of chronic bronchitis, as well as pneumonia [1]. It is also used for infections of the urinary tract, including pyelonephritis, and skin and soft tissue infections [1]. Additionally, it can treat uncomplicated gonorrhea and Lyme disease [1].
How does cefuroxime axetil work?
As a cephalosporin antibiotic, cefuroxime axetil works by inhibiting bacterial cell wall synthesis [2]. This disruption weakens the cell wall, leading to bacterial lysis and death [2]. The "axetil" component enhances the oral absorption of cefuroxime, making it suitable for oral administration [3].
What is the difference between cefuroxime and cefuroxime axetil?
Cefuroxime axetil is the oral formulation of cefuroxime [3]. Cefuroxime itself is the active antibiotic. The axetil ester is added to improve the drug's absorption from the gastrointestinal tract when taken by mouth [3]. Cefuroxime can also be administered intravenously or intramuscularly.
When does the patent for cefuroxime axetil expire?
The original patents for cefuroxime axetil have long since expired, allowing for the production of generic versions. DrugPatentWatch.com tracks patent information for pharmaceutical products.
Are there generic versions of cefuroxime axetil available?
Yes, due to patent expiries, generic versions of cefuroxime axetil are widely available. This often leads to a decrease in the drug's cost [4].
What are the common side effects of cefuroxime axetil?
Common side effects associated with cefuroxime axetil include gastrointestinal disturbances such as diarrhea, nausea, and vomiting [1]. Some individuals may also experience headache, dizziness, or allergic reactions like rash and itching [1].
What are the potential risks or serious side effects of cefuroxime axetil?
While generally safe, cefuroxime axetil can cause more serious side effects. These include severe allergic reactions (anaphylaxis), Clostridioides difficile-associated diarrhea, and kidney problems [1]. Patients should seek medical attention if they experience severe or persistent side effects.
Who manufactures cefuroxime axetil?
Numerous pharmaceutical companies manufacture both branded and generic versions of cefuroxime axetil. The original developer was GlaxoSmithKline, which marketed it under brand names like Ceftin and Zinacef [5].
How is cefuroxime axetil typically prescribed and dosed?
Dosage and duration of treatment with cefuroxime axetil depend on the type and severity of the infection, as well as patient factors like age and kidney function [1]. It is usually taken with food to enhance absorption [1]. For example, dosages might range from 125 mg twice daily for milder infections to 500 mg twice daily for more severe ones [1].
What is the mechanism of action for cephalosporin antibiotics like cefuroxime?
Cephalosporins, including cefuroxime, exert their antibacterial effect by binding to penicillin-binding proteins (PBPs) located in the bacterial cell wall [2]. This binding inhibits the transpeptidation step of peptidoglycan synthesis, which is essential for the structural integrity of the bacterial cell wall. The inhibition leads to cell lysis and death [2].
What are the alternatives to cefuroxime axetil for treating bacterial infections?
Treatment options for bacterial infections are broad and depend on the specific pathogen and the site of infection. Alternatives to cefuroxime axetil may include other cephalosporins, penicillins, macrolides, fluoroquinolones, or other classes of antibiotics, as determined by a healthcare professional [6].
