Ceftriaxone + Sulbactam is a broad-spectrum combination antibiotic used to treat moderate to severe bacterial infections.

Ceftriaxone is a bactericidal antibiotic that inhibits bacterial cell wall synthesis, causing bacterial death.

Sulbactam is a beta-lactamase inhibitor that protects Ceftriaxone from enzymatic degradation, making the combination effective against beta-lactamase producing bacteria.
