Ceftriaxone Injection is a broad-spectrum antibiotic used to treat bacterial infections. Once administered, Ceftriaxone Injection works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins, disrupting the production of peptidoglycan, a crucial component of bacterial cell walls. This weakens the cell structure, causing bacteria to rupture and die. Ceftriaxone Injection is effective against both Gram-positive and Gram-negative bacteria, making it versatile for infections like pneumonia, meningitis, and sepsis. After injection, ceftriaxone injection distributes widely in body tissues and fluids, maintaining high concentrations to combat infection. It’s typically administered intravenously or intramuscularly, with effects starting within hours.
