4.2 Drug Indication

For prophylaxis and treatment of bacterial infections.


FDA Label


5 Pharmacology and Biochemistry
5.1 Pharmacology

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.


5.2 MeSH Pharmacological Classification

5.4 ATC Code

J01D - Other beta-lactam antibacterials

J01DC - Second-generation cephalosporins

J01DC05 - Cefotetan


5.5 Absorption, Distribution and Excretion

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.


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)]


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)]


5.6 Metabolism/Metabolites

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.


5.7 Biological Half-Life

In volunteers with reduced renal function, the plasma half-life of cefotetan is prolonged


5.8 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.
