1. Ceftriaxone Sodium 1g IV Fig. 1.1 Ceftriaxone (Rocephin) It inhibits the cell wall synthesis promoting osmotic instability‚ usually bactericidal. It hinders or kills bacteria. Ceftriaxone sodium is a broad-spectrum bactericidal cephalosporin antibiotic. Ceftriaxone is active in vitro against a wide range of Gram-positive and Gram-negative organisms‚ which include β-lactamase producing strains. Ceftriaxone is indicated in the treatment of the following infections either before the infecting
