Pharmacology
IndicationCefacetrile is a broad-spectrum first generation cephalosporin antibiotic effective in Gram-positive and Gram-negative bacterial infections.
PharmacodynamicsCefacetrile is effective against many Gram-positive bacterial strains and somewhat less effective against Gram-negative species. It works by inhibition of bacterial cell wall synthesis. It attains high serum levels and is excreted quickly via the urine.
Mechanism of actionIn vitro tests demonstrate that the bactericidal action of cephalosporins results from inhibition of cell wall synthesis. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins.
