์์ฉ ๊ธฐ์ : Cefadroxil is a **time-dependent, bactericidal** antibiotic. It exerts its effect by binding to specific **Penicillin-Binding Proteins (PBPs)** located inside the bacterial cell wall. * Binding to PBPs โ **Inhibition of peptidoglycan cross-linking** (the structural backbone of the bacterial cell wall) โ Weakening of the cell wall โ Activation of bacterial autolysins โ **Cell lysis and death**. Because it is a time-dependent antibiotic, maintaining serum drug concentrations above the Minimum Inhibitory Concentration (MIC) for the majority of the dosing interval is critical for clinical efficacy.

Acute oral cephalosporin overdoses are unlikely to cause significant problems other than **gastrointestinal distress** (vomiting, diarrhea, anorexia). Massive overdoses or prolonged use, particularly in patients with compromised kidney function, may theoretically lead to neurotoxicity, neutropenia, hepatitis, or nephrotoxicity. Treatment is generally supportive and symptomatic.
