Pharmacology

Indication

For prophylaxis and treatment of bacterial infections.

Pharmacodynamics

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.

Mechanism of action

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.

TargetActionsOrganism
APenicillin-binding protein 3
inhibitor
Streptococcus pneumoniae
Absorption
Not Available
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)]
