3、Mechanism and clinical use:
Bacitracin Zinc is used in medicine as a polypeptide antibiotic. Bacitracin zinc has bactericidal action for Gram-positive bacteria. The mechanism of action: act on cell wall, bind with cell wall of sensitive bacteria, damage cell wall integrity, and give rise to outflow of important materials in cell.
It can effectively inhibit Gram-positive bacteria and some Gram-negative bacteria. The rate of bacterial resistance to bacteria is slow. There is no cross resistance with other antibiotics. It can promote the growth of livestock and poultry, and improve feed conversion rate.
On June 2019, API Bacitracin Zinc was granted “written confirmation for active substance exported to EU”.
