Cefotetan. A review of its antibacterial activity, pharmacokinetic properties and therapeutic use.
Cefotetan is a new semisynthetic cephamycin antibiotic administered intravenously or intramuscularly. It has a broad spectrum of activity against Gram-negative aerobic and most clinically important Gram-positive and anaerobic bacteria, and is generally more active against Gram-negative bacteria than the 'first and second generation' agents. Cefotetan is particularly active against Enterobacteriaceae but has little activity against Pseudomonas aeruginosa. An extended plasma elimination half-life of about 3.5 hours, and relatively high achievable serum and tissue levels, enables cefotetan to be administered on a twice daily basis in the treatment of mild to severe infections. Cefotetan has shown good clinical efficacy in intra-abdominal, obstetric and gynaecological infections, postoperative wound infections, and infections in immunocompromised patients - all of which are often complicated due to their polymicrobial nature or by the presence of anaerobic pathogens. A satisfactory clinical response is achieved in over 90% of paediatric patients with acute otorhinolaryngological infections, whereas in the treatment of chronic disease, as with other agents, the efficacy is dramatically reduced. Like other cephalosporins, cefotetan is effective in treating patients with complicated urinary tract infections and lower respiratory tract infections. Its efficacy in urinary tract infections is at least as good as cefoxitin, although in this and some other clinical areas its activity relative to that of other cephamycins and cephalosporins remains to be assessed. Thus, with its convenient twice daily dosage schedule, cefotetan would appear to be a useful addition to a rapidly expanding group of antibacterial agents.
