Ceftriaxone sodium

Ceftriaxone Sodium is the sodium salt form of ceftriaxone, a beta-lactam, third-generation cephalosporin antibiotic with bactericidal activity. Ceftriaxone binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. PBPs participate in the terminal stages of assembling the bacterial cell wall, and in reshaping the cell wall during cell division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis. Compared to the second and first generation cephalosporins, ceftriaxone is more active against gram-negative bacteria and less active against gram-positive bacteria. Ceftriaxone also crosses the blood-brain barrier and reaches therapeutic concentrations in the central nervous system (CNS). It is grouped under the following drug class(es): Beta-lactams. Its therapeutic use is listed as antibiotics. The directory classifies it as a commercial API with a semi-synthetic source/manufacturing origin. Other names for this substance include Cefraden, Rocefin and Megion. It is listed as a controlled drug substance (Schedule I). Its PubChem CID is 23715082.
