Label directions

  • 5–10 mg cefoperazone per kg body weight by IM or IV route [1].
  • The pack also contains one unit of sterile water for injection, 20 mL [1].

Warnings and precautions

  • Hypersensitivity reactions have occurred with cephalosporins, with cross-reactivity to penicillin allergies possible [2].

About cefoperazone (the active ingredient)

Third-generation cephalosporin (beta-lactam) antibacterial.

How it works

As a beta-lactam, it inhibits the penicillin-binding proteins and so bacterial cell wall synthesis [4]. Biliary elimination of newer cephalosporins such as cefoperazone may be appreciable [2].

Key safety points

  • Hypersensitivity reactions have occurred with cephalosporins, with cross-reactivity to penicillin allergies possible [2].
  • Cephalosporin injections IM can be painful, and repeated IV administration may lead to local phlebitis [2].

About sulbactam (the active ingredient)

Beta-lactamase inhibitor.

How it works

Inhibitors of beta-lactamases (e.g. clavulanic acid and sulbactam) were added to minimise destruction of the partner beta-lactam drug by bacterial enzymes [4].
