Cefuroxime axetil is an oral prodrug of cefuroxime [1]. This means that after administration, cefuroxime axetil is metabolized in the body to release active cefuroxime [1].
What is the difference in how they are administered?
Cefuroxime axetil is typically administered orally in tablet or suspension form [1]. Cefuroxime itself is often administered intravenously or intramuscularly, although oral formulations of cefuroxime (not as the axetil prodrug) also exist [2]. The axetil ester formulation enhances the oral bioavailability of cefuroxime [1].
Why is cefuroxime axetil used instead of just cefuroxime?
The primary reason for using cefuroxime axetil is to improve absorption from the gastrointestinal tract. Cefuroxime, when taken orally, is not well absorbed [1]. The axetil ester modification makes the drug more lipophilic, facilitating its passage through the intestinal wall and subsequent hydrolysis to the active cefuroxime within the body [1]. This allows for effective treatment of infections with an oral medication, avoiding the need for injections in many cases.
What types of infections are treated with cefuroxime axetil?
Cefuroxime axetil is used to treat a variety of bacterial infections. These can include [3]:
* Respiratory tract infections (e.g., acute bronchitis, exacerbations of chronic bronchitis, pneumonia)
* Urinary tract infections (e.g., cystitis, pyelonephritis)
* Skin and soft tissue infections (e.g., cellulitis, impetigo)
* Pharyngitis and tonsillitis
* Lyme disease (early stages)
How does cefuroxime axetil work?
Cefuroxime is a second-generation cephalosporin antibiotic [1]. It works by inhibiting bacterial cell wall synthesis [1]. This disruption leads to the death of the bacteria, thereby combating the infection [1].
Are there any safety concerns with cefuroxime axetil?
Common side effects associated with cefuroxime axetil include diarrhea, nausea, headache, and dizziness [3]. As with all antibiotics, there is a risk of developing Clostridioides difficile-associated diarrhea [3]. Patients with known hypersensitivity to cephalosporins or penicillins should use cefuroxime axetil with caution [3].
