Fex 750mg Tablet works by stopping bacteria from building their protective cell walls. It binds to specific proteins in the bacteria, blocking the formation of peptidoglycan, a key component of the cell wall. Without this support, the bacterial wall becomes weak and breaks, leading to the death of the bacteria. This makes Fex 750mg Tablet effective in treating bacterial infections.
