Pharmacology
IndicationUsed to prevent infection during surgery and to treat many kinds of infections of the blood, bone or joints, respiratory tract, skin, and urinary tract.
PharmacodynamicsCefalotin (INN) or cephalothin (USAN) is a semisynthetic first generation cephalosporin having a broad spectrum of antibiotic activity that is administered parenterally.
Mechanism of actionThe bactericidal activity of cefalotin results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). The PBPs are transpeptidases which are vital in peptidoglycan biosynthesis. Therefore, their inhibition prevents this vital cell wall compenent from being properly synthesized.
