Description
Indication & Scope
Unasyn® is a prescription β-lactam/β-lactamase inhibitor combination indicated for the treatment of susceptible bacterial infections, including respiratory tract, urinary tract, intra-abdominal, gynecologic, skin and soft tissue, bone and joint infections, septicemia, and gonorrhea. It is also indicated for perioperative prophylaxis in abdominal and gynecologic surgery.
- Mechanism: Sulbactam irreversibly inhibits β-lactamase enzymes, protecting ampicillin from enzymatic degradation and restoring antibacterial activity against β-lactamase-producing organisms.
- Drug class: Aminopenicillin/β-lactamase inhibitor combination.
- Clinical use: Treatment of susceptible bacterial infections and prevention of postoperative infections in selected surgical procedures.
