Cefixime is an oral antibiotic used to treat a variety of bacterial infections. It belongs to the cephalosporin class of antibiotics and works by preventing bacteria from forming their cell walls, leading to their death [1].
What kinds of infections does Cefixime treat?
Cefixime is prescribed for infections affecting the following areas:
* Respiratory Tract: Including bronchitis and pneumonia [1].
* Urinary Tract: Such as cystitis and uncomplicated urinary tract infections [1].
* Ear, Nose, and Throat: Such as sinusitis, pharyngitis, tonsillitis, and otitis media [1].
* Genital Tract: Including uncomplicated gonorrhea [1].
How does Cefixime work?
Cefixime is a third-generation cephalosporin antibiotic. It targets specific enzymes called penicillin-binding proteins (PBPs) that are essential for the synthesis of peptidoglycan, a key component of bacterial cell walls. By binding to these PBPs, cefixime inhibits the cross-linking of peptidoglycan strands, thereby weakening the cell wall and ultimately causing the bacterial cell to lyse and die [2].
What is the typical dosage and duration of Cefixime treatment?
Dosage and duration of treatment depend on the type and severity of the infection, as well as the patient's age and kidney function. For adults and children weighing over 30 kg, a common dose is 400 mg once daily, or 200 mg every 12 hours. For children weighing less than 30 kg, the dose is usually calculated based on body weight. Treatment typically lasts for 5 to 10 days [1].
What are the potential side effects of Cefixime?
Common side effects reported with cefixime use include diarrhea, nausea, vomiting, abdominal pain, and headache. Less common side effects may include dizziness, rash, itching, and changes in blood counts. Severe adverse reactions, though rare, can include severe allergic reactions, Clostridium difficile-associated diarrhea, and kidney problems [1].
When might Cefixime not be suitable?
Cefixime should not be used by individuals with a known hypersensitivity to cefixime or other cephalosporin antibiotics. Caution is advised for patients with a history of penicillin allergy, severe kidney impairment, or gastrointestinal diseases [1].
Can Cefixime be used during pregnancy or breastfeeding?
The use of cefixime during pregnancy should be limited to situations where it is clearly needed, as its safety in pregnant women has not been definitively established. It is not known whether cefixime is excreted in human milk, so caution should be exercised when administering it to breastfeeding women [1].
How does Cefixime's patent status affect its availability?
