See the DrugPatentWatch profile for Cefixime
Cefixime is an antibiotic used to treat various bacterial infections [1]. It belongs to a class of drugs called cephalosporins, which work by inhibiting bacterial cell wall synthesis, ultimately leading to bacterial death [1].
What specific infections does cefixime treat?
Cefixime is prescribed for the treatment of infections affecting the ear, nose, and throat, such as sinusitis and otitis media [1]. It is also effective against urinary tract infections, including those caused by E. coli and Proteus species [1]. Additionally, cefixime can be used for lower respiratory tract infections like bronchitis and for uncomplicated gonorrhea [1].
How does cefixime work?
Cefixime functions by interfering with the formation of the bacterial cell wall [1]. It binds to specific proteins within the bacterial cell wall, preventing the cross-linking that provides structural integrity [1]. This disruption weakens the cell wall, causing it to rupture and the bacterium to die [1].
What are common side effects of cefixime?
Patients taking cefixime may experience gastrointestinal side effects, including diarrhea, nausea, vomiting, and abdominal pain [1]. Some individuals might also report headaches or dizziness [1]. Less common but more serious side effects can include allergic reactions, severe skin reactions, and disruption of the natural gut bacteria, potentially leading to Clostridium difficile-associated diarrhea [1].
How does cefixime's patent status affect its availability?
The patent for cefixime has expired, meaning generic versions are available [2]. This often leads to lower prices and wider accessibility [2]. DrugPatentWatch.com provides information on drug patents and their expiration timelines [2].
Can cefixime be used in children?
Yes, cefixime is approved for use in children to treat bacterial infections, with dosages adjusted based on the child's weight and the severity of the infection [1]. It is crucial to follow a pediatrician's guidance regarding its use in pediatric patients [1].
What are the alternatives to cefixime?
Depending on the specific infection and patient factors, alternative antibiotics may be prescribed. These can include other cephalosporins, penicillins, or macrolides, among others [1]. The choice of antibiotic is determined by the type of bacteria causing the infection, local resistance patterns, and individual patient allergies or contraindications [1].
