General description

Cefoxitin is a β-lactam that belongs to the group of cephamycin antibiotics and is considered a 2nd generation cephalosporin. It shows resistance to β-lactamases and is used to treat a broad spectrum of bacterial infections caused by gram-positive and gram-negative bacteria, such as bronchitis, pharyngitis, meningitis, and urinary tract infection among others. It is used for intravenous and intramuscular injections. It is found to be active against Bacteroides and is therapeutically used for the treatment of mixed aerobic-anaerobic infections.

Application

The analytical standard can be used to:
  • Determine cefoxitin sodium using four stability-indicating spectrophotometric methods in the presence of its alkaline degradation products in its pure form and pharmaceutical dosage forms
  • Separate and measure cefoxitin sodium in commercial drug products by high-performance liquid chromatography (HPLC)
