Ceftazidime Injection

• Type: Antibiotic injection

• Drug Class: Third-generation cephalosporin antibiotic

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

How It Works

• Ceftazidime works by inhibiting bacterial cell wall synthesis, which leads to weakening and rupture of the cell wall and ultimately bacterial death.

• It has strong activity against gram-negative bacteria, especially Pseudomonas aeruginosa, a common cause of hospital-acquired infections.

Common Uses

Ceftazidime is commonly used for serious bacterial infections, including:

• Hospital-acquired pneumonia (including ventilator-associated pneumonia)

• Sepsis (bloodstream infections)

• Febrile neutropenia (fever in patients with very low white blood cell count)

• Complicated urinary tract infections

• Complicated skin and soft tissue infections

• Bone and joint infections

• Meningitis caused by susceptible bacteria

• Intra-abdominal infections (often used with metronidazole)

Advantages

• Excellent coverage against Pseudomonas and other resistant gram-negative organisms

• Can be used in both community and hospital settings

• Good penetration into cerebrospinal fluid (CSF), useful for meningitis caused by gram-negative bacteria

Possible Side Effects

• Pain, redness, or swelling at injection site

• Diarrhea, nausea, vomiting

• Rash or mild allergic reactions

• Changes in liver or kidney function tests

• Rare: severe allergic reaction (anaphylaxis)

• Very rare: seizures (mostly in patients with kidney impairment if dose is not adjusted)

Precautions

• Kidney function monitoring is required; dose must be adjusted in patients with kidney problems

• Caution in patients allergic to penicillins or other cephalosporins

• Overuse can lead to antibiotic resistance or superinfections (such as Clostridium difficile colitis)

• Should be given under the supervision of a trained healthcare professional
