How does this medicine work?[edit | edit source]

The sodium salt form of ceftriaxone, a beta-lactam, third-generation cephalosporin antibiotic with bactericidal activity.
Ceftriaxone is a bactericidal agent that acts by inhibition of bacterial cell wall synthesis.
Ceftriaxone has activity in the presence of some beta-lactamases, both penicillinases and cephalosporinases, of Gram-negative and Gram-positive bacteria.
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).

Ceftriaxone has been shown to be active against most isolates of the following bacteria: Gram-negative Bacteria:

Gram-positive Bacteria:

Anaerobic Bacteria:

Recommended dosage:

In Pediatric Patients:

For the treatment of skin and skin structure infections, the recommended total daily dose is 50 to 75 mg/kg given once a day (or in equally divided doses twice a day). The total daily dose should not exceed 2 grams.
For the treatment of serious miscellaneous infections other than meningitis, the recommended total daily dose is 50 to 75 mg/kg, given in divided doses every 12 hours. The total daily dose should not exceed 2 grams.
In the treatment of meningitis, it is recommended that the initial therapeutic dose be 100 mg/kg (not to exceed 4 grams). Thereafter, a total daily dose of 100 mg/kg/day (not to exceed 4 grams daily) is recommended. The daily dose may be administered once a day (or in equally divided doses every 12 hours). The usual duration of therapy is 7 to 14 days.

In Adults:

The usual adult daily dose is 1 to 2 grams given once a day (or in equally divided doses twice a day) depending on the type and severity of infection.
For infections caused by Staphylococcus aureus (MSSA), the recommended daily dose is 2 to 4 grams, in order to achieve >90% target attainment. The total daily dose should not exceed 4 grams.
If Chlamydia trachomatis is a suspected pathogen, appropriate antichlamydial coverage should be added, because ceftriaxone sodium has no activity against this organism.
For preoperative use (surgical prophylaxis), a single dose of 1 gram administered intravenously 1/2 to 2 hours before surgery is recommended.
Generally, Ceftriaxone Injection, USP therapy should be continued for at least 2 days after the signs and symptoms of infection have disappeared. The usual duration of therapy is 4 to 14 days; in complicated infections, longer therapy may be required.
When treating infections caused by Streptococcus pyogenes, therapy should be continued for at least 10 days.

No dosage adjustment is necessary for patients with impairment of hepatic impairment or mild to moderate renal impairment.

Administration:

Ceftriaxone injection comes as a powder to be mixed with liquid, or as a premixed product, to be injected intravenously over a period of 30 or 60 minutes.
Ceftriaxone injection can also be given intramuscularly.
It is sometimes given as a single dose and sometimes given once or twice a day for 4-14 days, depending on the type of infection being treated.
You may receive ceftriaxone injection in a hospital or doctor's office, or you may administer the medication at home.
If you will be receiving ceftriaxone injection at home, your healthcare provider will show you how to use the medication.
Be sure that you understand these directions, and ask your healthcare provider if you have any questions.
You should begin to feel better during the first few days of your treatment with ceftriaxone injection.
If your symptoms do not improve or get worse, call your doctor.

What side effects can this medication cause?[edit | edit source]

The most common side effects of this medicine may include:

diarrhea, eosinophilia, thrombocytosis, leukopenia, and elevations of SGOT and SGPT.

Less common, but serious side effects may include:

Hypersensitivity reactions
Ceftriaxone-calcium precipitates
Clostridium difficile-associated diarrhea
Hemolytic anemia

What special precautions should I follow?[edit | edit source]

Serious, occasionally fatal, hypersensitivity (anaphylactic) reactions have been reported with ceftriaxone. If an allergic reaction to Ceftriaxone for Injection, USP occurs, discontinue the drug. Serious acute hypersensitivity reactions may require treatment with epinephrine and other emergency measures including oxygen, corticosteroids, intravenous fluids, intravenous antihistamines, pressor amines, and airway management, as clinically indicated.
Precipitation of ceftriaxone-calcium can occur when Ceftriaxone for Injection, USP is mixed with calcium-containing solutions in the same intravenous administration line. Ceftriaxone for Injection must not be administered simultaneously with calcium-containing intravenous solutions, including continuous calcium-containing infusions.
Serious neurological adverse reactions have been reported with ceftriaxone use. If neurological adverse reactions associate with Ceftriaxone for Injection therapy occur, discontinue Ceftriaxone for Injection and institute appropriate supportive measures. Make appropriate dosage adjustments in patients with severe renal impairment.
Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including ceftriaxone, and may range in severity from mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.
An immune mediated hemolytic anemia has been observed in patients receiving cephalosporin class antibacterials including ceftriaxone. If a patient develops anemia while on Ceftriaxone for Injection, USP, the diagnosis of a cephalosporin-associated anemia should be considered and Ceftriaxone for Injection, USP stopped until the etiology is determined.
There have been reports of sonographic abnormalities in the gallbladder of patients treated with ceftriaxone sodium; some of these patients also had symptoms of gallbladder disease. Therefore, ceftriaxone should be discontinued in patients who develop signs and symptoms suggestive of gallbladder disease and/or the sonographic findings described above.
In patients with both hepatic and significant renal disease, Ceftriaxone for Injection dosage should not exceed 2 grams daily.
In patients with both hepatic impairment and significant renal disease, Ceftriaxone for Injection dosage should not exceed 2 grams per day.
Cases of pancreatitis, possibly secondary to biliary obstruction, have been reported in patients treated with ceftriaxone sodium. Careful observation of the patient is essential. If superinfection occurs during therapy, appropriate measures should be taken.
Alterations in prothrombin times have occurred in patients treated with ceftriaxone sodium. Vitamin K administration (10 mg weekly) may be necessary if the prothrombin time is prolonged before or during therapy.
Ceftriaxone is also associated with rare instances of immunoallergic, usually cholestatic hepatitis similar to the injury associated with other cephalosporins.
Ceftriaxone is excreted in human breast milk. Caution should be exercised when Ceftriaxone for Injection is administered to a nursing woman.
