Ceftriaxone Sodium Injection 500 mg is used to treat a wide range of bacterial infections. It belongs to the cephalosporin class of antibiotics and works by inhibiting cell wall synthesis, effectively eliminating bacteria. This antibiotic is commonly used for infections such as pneumonia, urinary tract infections, skin infections, and sexually transmitted infections like gonorrhea. It is administered intravenously or intramuscularly, ensuring rapid delivery to combat severe or systemic infections, providing effective treatment to support recovery and prevent complications. Ceftriaxone Sodium Injection is a broad-spectrum, third-generation cephalosporin antibiotic used for the treatment of various bacterial infections. It is highly effective against a wide range of Gram-positive and Gram-negative bacteria. This product by Pfizer Injectables is provided in a dosage form of 500 mg of ceftriaxone per 1 mL vial, and it is packaged in packs containing 10 vials. Details and Features: Dosage Form: 500 mg of Ceftriaxone per vialVolume: Each vial contains powder for reconstitution to achieve the desired concentration for injectionPackaging: 10 vials per packUse: Indicated for intramuscular (IM) or intravenous (IV) administrationApplication: Commonly used for treating infections such as pneumonia, urinary tract infections, gonorrhea, septicemia, meningitis, and surgical prophylaxis Mechanism of Action: Ceftriaxone works by inhibiting bacterial cell wall synthesis. It targets the penicillin-binding proteins (PBPs) within the bacterial cell wall, disrupting the cross-linking of peptidoglycan chains, which are crucial for bacterial cell wall structural integrity. This leads to cell lysis and death, particularly in actively dividing bacteria. Warnings: Hypersensitivity: Contraindicated in patients with known hypersensitivity to ceftriaxone, cephalosporins, or beta-lactam antibiotics. Interaction with Calcium-Containing IV Solutions: Reconstituted Ceftriaxone should not be mixed or simultaneously infused with calcium-containing IV solutions due to the risk of crystalline precipitate formation. Neonatal Safety: Use is cautioned in neonates due to the risk of bilirubin encephalopathy. Clostridium difficile-Associated Diarrhea (CDAD): Prolonged use of antibiotics like ceftriaxone may lead to overgrowth of non-susceptible organisms, including fungi. Monitoring for signs of pseudomembranous colitis is advised. Renal and Hepatic Impairment: Use cautiously and adjust dosing in patients with significant renal and combined renal/hepatic impairment. Side Effects: While generally well-tolerated, Ceftriaxone may have some side effects, including: Local Reactions: Pain, induration, and tenderness at the IM injection site; potential thrombophlebitis after IV administration Gastrointestinal: Diarrhea, nausea, vomiting, risk of CDAD with severe cases Hypersensitivity Reactions: Rash, pruritus, fever, and, on rare occasions, a more severe anaphylactic reaction Hematologic: Eosinophilia, thrombocytosis, leukopenia Hepatic: Transient elevations in liver enzymes Ceftriaxone administration should always be conducted under the guidance of a healthcare professional with appropriate dosing and observation to manage any adverse effects and maximize therapeutic efficacy.
