Mode of Action1

Zinnat (Cefuroxime axetil) is an antibacterial for systemic use. It is a second‐generation cephalosporin.

Zinnat (Cefuroxime axetil) undergoes hydrolysis by esterase enzymes to the active antibiotic, cefuroxime. Zinnat
inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). This results in the
interruption of cell wall (peptidoglycan) biosynthesis, which leads to bacterial cell lysis and death.


Zinnat is indicated for the treatment of the infections listed below in adults and children from the age of 3 months.

  • Acute streptococcal tonsillitis and pharyngitis.
  • Acute bacterial sinusitis.
  • Acute otitis media.
  • Acute exacerbations of chronic bronchitis.
  • Cystitis.
  • Pyelonephritis.
  • Uncomplicated skin and soft tissue infections.
  • Treatment of early Lyme disease.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.
