์์ฉ ๊ธฐ์ : Dicloxacillin is a **bactericidal** beta-lactam antibiotic. * It binds to specific **Penicillin-Binding Proteins (PBPs)** located inside the bacterial cell wall. * This binding inhibits the third and final stage of bacterial cell wall synthesis โ blocks the cross-linking of peptidoglycan. * The weakened cell wall leads to the activation of autolysins โ **cell lysis** and bacterial death. * Its bulky side chain prevents the beta-lactam ring from being hydrolyzed by staphylococcal penicillinase.

- Anorexia
- Vomiting
- Diarrhea
- Antibiotic-associated diarrhea (superinfections)
- Hypersensitivity reactions (rashes, fever, eosinophilia, anaphylaxis)
- Neurotoxicity (ataxia at very high doses)
- Elevated liver enzymes
- Tachypnea
- Dyspnea
- Edema
- Tachycardia

- Aminoglycosides ยท In vitro evidence of synergism with dicloxacillin against S. aureus strains; however, penicillins can inactivate aminoglycosides in vitro, so do not mix in the same syringe/fluid line.
- Cyclosporine ยท Dicloxacillin may reduce cyclosporine levels.
- Probenecid ยท Competitively blocks the tubular secretion of dicloxacillin, thereby increasing serum levels and serum half-lives.
- Tetracyclines ยท Theoretical antagonism; concurrent use is usually not recommended.
- Warfarin ยท Dicloxacillin may cause decreased warfarin efficacy.

- Toxic clinical signs (GI upset, hypersensitivity)

Acute oral penicillin overdoses are unlikely to cause significant problems other than **GI distress** (vomiting, diarrhea). In humans, very high dosages of parenteral penicillins, especially in patients with renal disease, have induced **CNS effects** (neurotoxicity).
