์์ฉ ๊ธฐ์ : Cephapirin is a **time-dependent, bactericidal** beta-lactam antibiotic. * Binds to specific **penicillin-binding proteins (PBPs)** (such as **transpeptidases**, **carboxypeptidases**, and **endopeptidases**) located inside the bacterial cytoplasmic membrane. * Inhibition of these enzymes โ blocks the final stages of mucopeptide (peptidoglycan) synthesis in the bacterial cell wall. * Defective cell wall formation โ creates an osmotically unstable spheroplast โ **cell lysis** and death. * *Note*: Like other beta-lactams, it is most effective against actively growing and dividing bacteria.
