CLINICAL PHARMACOLOGY A wide range of antibacterial action is provided by the overlapping spectra of neomycin, polymyxin B sulfate, and gramicidin. Neomycin is bactericidal for many gram-positive and gram-negative organisms. It is an aminoglycoside antibiotic which inhibits protein synthesis by binding with ribosomal RNA and causing misreading of the bacterial genetic code.
Polymyxin B is bactericidal for a variety of gram-negative organisms. It increases the permeability of the bacterial cell membrane by interacting with the phospholipid components of the membrane. Gramicidin is bactericidal for a variety of gram-positive organisms.
It increases the permeability of the bacterial cell membrane to inorganic cations by forming a network of channels through the normal lipid bilayer of the membrane. Microbiology: Neomycin sulfate, polymyxin B sulfate, and gramicidin together are considered active against the following microorganisms: Staphylococcus aureus , streptococci, including Streptococcus pneumoniae , Escherichia coli, Haemophilus influenzae, Klebsiella-Enterobacter species, Neisseria species, and Pseudomonas aeruginosa . The product does not provide adequate coverage against Serratia marcescens .
