Ceftriaxone Sodium + Sulbactam Injection

• Type: Combination antibiotic injection

• Drug Class:

  • Ceftriaxone: Third-generation cephalosporin antibiotic

  • Sulbactam: Beta-lactamase inhibitor

• Form: Sterile powder for reconstitution, given intravenously (IV) or intramuscularly (IM)

How It Works

• Ceftriaxone works by blocking bacterial cell wall synthesis, killing the bacteria.

• Sulbactam protects ceftriaxone from being destroyed by beta-lactamase enzymes produced by resistant bacteria.

• Together, they provide broader antibacterial coverage, including many resistant strains.

Common Uses

This combination is used for moderate to severe bacterial infections, including:

• Pneumonia (community-acquired or hospital-acquired)

• Sepsis (bloodstream infections)

• Complicated urinary tract infections (UTIs)

• Skin and soft tissue infections

• Intra-abdominal infections (with or without metronidazole)

• Biliary tract infections

• Bone and joint infections

• Pelvic inflammatory disease

Advantages

• Broader coverage than ceftriaxone alone

• Effective against many beta-lactamase–producing bacteria

• Can often be given once or twice daily due to ceftriaxone’s long duration

• Good penetration into tissues, including bile ducts (helpful for biliary tract infections)

Possible Side Effects

• Pain, swelling, or irritation at injection site

• Diarrhea, nausea, or vomiting

• Mild rash or allergic reaction

• Headache, fever

• Changes in liver enzymes or kidney function (in blood tests)

• Rare: gallbladder sludge/stones with prolonged use

• Very rare: severe allergic reaction (anaphylaxis)

Precautions

• Use with caution if allergic to penicillins or cephalosporins

• Liver and kidney function monitoring may be needed in long-term therapy

• Overuse or misuse can lead to antibiotic resistance

• Should be administered under medical supervision, especially for severe infections
