Ceftriaxone + Tazobactum is a combination of two medicines: Ceftriaxone and Tazobactum.

Ceftriaxone is an antibiotic. It works by preventing the formation of the bacterial protective covering which is essential for the survival of bacteria.
Tazobactum is a beta-lactamase inhibitor which reduces resistance and enhances the activity of Ceftriaxone against bacteria.
