详细说明

DrugBank - DB01331

• Drug Groups: approved
• Description: Cefoxitin is a semi-synthetic, broad-spectrum cepha antibiotic for intravenous administration. It is derived from cephamycin C, which is produced by Streptomyces lactamdurans.
• Indication: For the treatment of serious infections caused by susceptible strains microorganisms.
• Pharmacology: Cefoxitin is a cephamycin antibiotic often grouped with the second-generation cephalosporins. It is active against a broad range of gram-negative bacteria including anaerobes. The methoxy group in the 7a position provides cefoxitin with a high degree of stability in the presence of beta-lactamases, both penicillinases and cephalosporinases, of gram-negative bacteria.
• Toxicity: The acute intravenous LD50 in the adult female mouse and rabbit was about 8.0 g/kg and greater than 1.0 g/kg, respectively. The acute intraperitoneal LD50 in the adult rat was greater than 10.0 g/kg.
• Affected Organisms: Enteric bacteria and other eubacteria
• Biotransformation: Minimal (approximately 85 percent of cefoxitin is excreted unchanged by the kidneys over a 6-hour period).
• Half Life: The half-life after an intravenous dose is 41 to 59 minutes.
• Elimination: Approximately 85 percent of cefoxitin is excreted unchanged by the kidneys over a 6-hour period, resulting in high urinary concentrations. Cefoxitin passes into pleural and joint fluids and is detectable in antibacterial concentrations in bile.
