Cefoperazone-Sulbactam
Cephalosporin · Antibiotic
Also known as Cefoperazone/Sulbactam, CPZ/SUL, Cefosul, Cefozon-S, Zosul
Mechanism
Cefoperazone, a third-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins, leading to bactericidal action. Sulbactam is a beta-lactamase inhibitor that irreversibly inactivates a broad spectrum of bacterial beta-lactamases, thereby protecting cefoperazone from degradation and extending its antimicrobial spectrum, especially against resistant strains.
Indications
Dosing
- Adult
- 2-4 g (cefoperazone component) IV/IM daily, given in equally divided doses every 12 hours. For severe infections, the dose may be increased up to 8 g/day (cefoperazone component) in 2-4 divided doses.
- Pediatric
- 40-80 mg/kg/day (cefoperazone component) IV/IM, given in 2-4 equally divided doses. For severe infections, up to 160 mg/kg/day (cefoperazone component) may be administered in 2-4 divided doses, not exceeding 8 g/day cefoperazone.
- Renal adjustment
- CrCl > 30 mL/min: No adjustment. CrCl 15-30 mL/min: Usual dose every 12 hours, but limit sulbactam to 1 g every 12 hours. CrCl < 15 mL/min: Usual dose every 12 hours, but limit sulbactam to 500 mg every 12 hours. Administer after hemodialysis.
- Hepatic adjustment
- In severe hepatic impairment and/or biliary obstruction, monitor cefoperazone levels; total daily cefoperazone dose should not exceed 4 g due to predominant biliary excretion.
- Geriatric
- No specific dose adjustment solely based on age. Consider age-related decrease in renal function.
- Max dose
- Cefoperazone: 8 g/day; Sulbactam: 4 g/day.
Pharmacokinetics
Contraindications
- Hypersensitivity to cefoperazone, sulbactam, other cephalosporins, penicillins, or any component of the formulation.
- History of severe hypersensitivity reaction to any other beta-lactam antibacterial agent.
Side effects
- Pseudomembranous colitis (C. difficile infection)
- Severe hypersensitivity reactions (anaphylaxis)
- Coagulopathy (vitamin K deficiency, bleeding)
- Seizures (especially in renal impairment)
- Neutropenia
- Thrombocytopenia
- Hemolytic anemia
- Cholestatic jaundice
Pregnancy & lactation
Category B. Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women.
Both cefoperazone and sulbactam are excreted in small amounts into breast milk. Generally considered compatible with breastfeeding, but monitor infant for potential adverse effects (e.g., diarrhea, candidiasis, allergic reaction).
