| Common Name | Cefalotin |
|---|
| Description | Cefalotin is only found in individuals that have used or taken this drug. It is a cephalosporin antibiotic.The 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. |
