์์ฉ ๊ธฐ์ : Cefotetan is a **bactericidal** time-dependent antibiotic. - It binds to specific **Penicillin-Binding Proteins (PBPs)** located inside the bacterial cell wall. - Binding โ inhibition of the third and final stage of bacterial cell wall synthesis (mucopeptide/peptidoglycan cross-linking). - This leads to weakened cell walls โ cell lysis and death mediated by bacterial autolysins. - As a cephamycin, it is highly resistant to degradation by many beta-lactamases produced by Gram-negative and anaerobic bacteria.

- Known hypersensitivity to cephamycins or cephalosporins
- Caution in patients with documented hypersensitivity to penicillins or other beta-lactams (cross-reactivity possible)
- Caution in patients with severe renal dysfunction (dose interval adjustment may be required)
์ด์๋ฐ์
- Pain at IM injection site
- Thrombophlebitis (IV administration)
- Hypersensitivity reactions (rash, fever, anaphylaxis)
- Bleeding tendencies (hypoprothrombinemia due to NMTT side chain)
- Gastrointestinal flora alteration (diarrhea, superinfections)
- Rarely: nephrotoxicity, neurotoxicity, neutropenia, thrombocytopenia at high doses
์ฝ๋ฌผ ์ํธ์์ฉ
- Alcohol ยท Potential for a disulfiram-like reaction (vomiting, etc.) due to the NMTT side chain.
- Aminoglycosides ยท Potential additive nephrotoxicity; do not mix together in the same syringe/fluid bag (administer separately). May have synergistic antibacterial activity.
- Nephrotoxic drugs (e.g., Amphotericin B) ยท Potential additive nephrotoxicity.
๋ชจ๋ํฐ๋ง
- Clinical efficacy (resolution of infection)
- Renal function in patients with pre-existing renal disease
- Signs of bleeding or coagulopathy (due to NMTT side chain)

Massive or chronic overdoses are required to cause significant adverse effects. **Seizures** are possible with extreme beta-lactam overdoses, particularly in patients with renal impairment. Treatment is supportive and symptomatic.
