Pharmacodynamics
Cefmetazole is a second-generation cephalosporin. The cephalosporins are bactericidal drugs with both gram-positive and gram-negative activity. They inhibit bacterial cell wall synthesis in a way similar to the penicillins. Cefmetazole is more active than 1st-generation cephalosporins against indole-positive <i>Proteus</i>, <i>Serratia</i>, anaerobic gram-negative bacilli (including <i>B. fragilis</i>), and some <i>E. coli</i>, <i>Klebsiella</i>, and <i>P. mirabilis</i>, but is less active than cefoxitin or cefotetan against most gram-negative bacilli.
Mechanism of ActionThe bactericidal activity of cefmetazole results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs).
Biological Half-Life1.50 ±0.14 hours
Metabolism/MetabolitesNo appreciable metabolism.
MeSH Pharmacological ClassificationSubstances that inhibit the growth or reproduction of BACTERIA.
Absorption, Distribution and ExcretionBioavailability is approximately 100% following intramuscular injection.
Cellular LocationsExtracellular
응용 분야
개요Cefmetazole is a cephamycin with a nonaromatic side chain at C-7. In addition to a fairly characteristic second-generation cephalosporin antimicrobial spectrum, it possess fairly significant anti-antiaerobic activity. The ejection of its C-3 side chain leads to alcohol intolerance of the disulfuram type and prolonged clotting times.
