Polymyxin B sulfate is similar with polymyxin E, and has either bacteriostatic or bactericidal effect on various kinds of gram-negative bacteria, such as Escherichia coli, Pseudomonas aeruginosa, Escherichia coli deputy, Klebsiella pneumoniae, acidophilus, Bordetella pertussis and Shigella dysentery.
It is mainly applied to the treatment of infection in wounds, the urinary tract, eyes, ears, and bronchus caused by Pseudomonas aeruginosa and other kinds of pseudomonas. It can also be applied for treating sepsis, peritonitis, and severe infection caused by aminoglycoside-resistant, third generation cephalosporins-resistant bacteria and Pseudomonas aeruginosa or other sensitive strains, such as bacteremia, endocarditis, pneumonia, and burn infection.
