Description

Ceftriaxone sodium 1 g is a broad-spectrum cephalosporin antibiotic used for the treatment of various bacterial infections. It exhibits bactericidal activity by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins, leading to cell lysis and death. It is effective against gram-positive and gram-negative bacteria, including Streptococcus pneumoniae, Escherichia coli, Neisseria gonorrhoeae, and Haemophilus influenzae.

Ceftriaxone is administered via intravenous or intramuscular injection. The dosing regimen varies based on the severity and type of infection. For most infections, the usual adult dose is 1 to 2 g once daily or divided into two doses. In meningitis and severe infections, higher doses up to 4 g per day may be required. For gonorrhea, a single intramuscular dose is typically sufficient.

Adverse effects include diarrhea, nausea, rash, and local injection site reactions. Serious reactions, such as Clostridium difficile-associated diarrhea, anaphylaxis, and hemolytic anemia, may occur. Patients with a history of hypersensitivity to cephalosporins or penicillins require caution. Renal and hepatic function should be monitored in prolonged therapy, and dosage adjustments may be necessary in severe renal impairment.
