Dược Lực Học : Cefotetan is a semisynthetic cephamycin antibiotic that is administered intravenously or intramuscularly. The drug is highly resistant to a broad spectrum of beta-lactamases and is active against a wide range of both aerobic and anaerobic gram-positive and gram-negative microorganisms.
Cơ Chế Tác Dụng : A semisynthetic cephamycin antibiotic that is administered intravenously or intramuscularly. The drug is highly resistant to a broad spectrum of beta-lactamases and is active against a wide range of both aerobic and anaerobic gram-positive and gram-negative microorganisms. [PubChem] The bactericidal action of cefotetan results from inhibition of cell wall synthesis by binding and inhibiting the bacterial penicillin binding proteins which help in the cell wall biosynthesis.
Dược Động Học :

▧ Volume of Distribution :
* 10.4 L [elderly patients (greater than 65 years) with normal renal function] * 10.3 L [healthy volunteers (aged 25 to 28 years)]
▧ Protein binding :
Cefotetan is 88% plasma protein bound.
▧ Metabolism :
No active metabolites of cefotetan have been detected; however, small amounts (less than 7%) of cefotetan in plasma and urine may be converted to its tautomer, which has antimicrobial activity similar to the parent drug.
▧ Route of Elimination :
No active metabolites of cefotetan have been detected; however, small amounts (less than 7%) of cefotetan in plasma and urine may be converted to its tautomer, which has antimicrobial activity similar to the parent drug. In normal patients, from 51% to 81% of an administered dose of Cefotetan is excreted unchanged by the kidneys over a 24 hour period, which results in high and prolonged urinary concentrations.
▧ Half Life :
In volunteers with reduced renal function, the plasma half-life of cefotetan is prolonged
▧ Clearance :
* 1.8 +/- 0.1 L/h [elderly patients with normal renal function (.65 years)] * 1.8 +/- 0.3 L/h [healthy volunteers (aged 25 to 28 years)]
Chỉ Định : For prophylaxis and treatment of bacterial infections.
Tương Tác Thuốc :
  • Acenocoumarol The cephalosporin, cefotetan, may increase the anticoagulant effect of acenocoumarol.
  • Amikacin Increased risk of nephrotoxicity
  • Anisindione The cephalosporin, cefotetan, may increase the anticoagulant effect of anisindione.
  • Dicoumarol The cephalosporin, cefotetan, may increase the anticoagulant effect of dicumarol.
  • Gentamicin Increased risk of nephrotoxicity
  • Kanamycin Increased risk of nephrotoxicity
  • Neomycin Increased risk of nephrotoxicity
  • Netilmicin Increased risk of nephrotoxicity
  • Probenecid Probenecid may increase the serum level of cefotetan.
  • Streptomycin Increased risk of nephrotoxicity
  • Tobramycin Increased risk of nephrotoxicity
  • Warfarin The cephalosporin, cefotetan, may increase the anticoagulant effect of warfarin.
