Ceftriaxone + Tazobactam is a combination antibiotic used to treat moderate to severe bacterial infections, including those caused by beta-lactamase producing bacteria.

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

Tazobactam is a beta-lactamase inhibitor that prevents bacteria from breaking down Ceftriaxone, making the combination effective against resistant strains.
