Polyfax is a topical antibiotic ointment widely used in the treatment and prevention of bacterial infections in minor wounds, burns, and skin grafts. It contains two active ingredients, polymyxin B sulfate and bacitracin zinc, which work together to inhibit the growth of various bacteria, effectively preventing them from spreading and causing infections. Polymyxin B targets the bacterial cell membrane, while bacitracin interferes with the bacteria's cell wall synthesis. This combination makes Polyfax a potent option for treating superficial infections caused by susceptible bacteria. It is commonly prescribed by healthcare professionals for its efficacy in promoting wound healing and preventing bacterial complications in minor skin injuries.
