How it works
It is a bactericidal preparation active against all the pathogens commonly found in bacterial infections of the ear. Polymixin B is bactericidal against a wide range of gram negative bacilli including Pseudomonas Spp., Escherichia coli, Enterobacter Spp., Klebsiella Spp., and Haemophilus influenzae. It exerts a bactericidal effect by binding to acid phospholipids in the cell wall and membranes of the bacterium, thereby rendering ineffective the osmotic barrier normally provided by the cell membrane. This leads to escape of the cell contents and the death of the organism.
