Mahacef-CV 200 Tablet is an antibiotic medicine used to treat bacterial infections in children. It contains Cefixime (cephalosporin) and Clavulanic acid. Cefixime works by inhibiting the formation of the bacterial cell wall (a protective covering) that is necessary for their survival. This causes damage to the bacterial cell wall and eventually leads to the death of the bacterial cell. Clavulanic acid inhibits the beta-lactamase enzyme, which prevents bacteria from destroying the efficacy of Cefixime.
