Mechanism of Action:

Ceftriaxone, a third-generation cephalosporin antibiotic, works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) inside the bacterial cell wall, disrupting the cross-linking of peptidoglycan layers, which are essential for cell wall structural integrity and maintenance. This disruption leads to cell wall breakdown and eventual cell lysis, effectively killing the bacteria.

Warnings:

• Hypersensitivity: Contraindicated in patients with known allergy to ceftriaxone, cephalosporins, or any of the excipients. Use with caution in those with a history of penicillin allergies due to possible cross-reactivity.
  
• Neonatal Risk: Not recommended for use in neonates with hyperbilirubinemia due to risk of bilirubin encephalopathy.
  
• Calcium Interaction: Avoid mixing with calcium-containing solutions due to the risk of precipitation, which can cause serious adverse effects.
  
• Gastrointestinal Effects: Potential development of Clostridium difficile-associated diarrhea (CDAD), ranging from mild diarrhea to fatal colitis.
  
• Renal and Hepatic Impairment: Dose adjustments may be needed for patients with significant renal or hepatic dysfunction.
