At a glance
Bacitracin Zinc + Polymixin B Eye prep is a combination antibiotic used for the treatment of bacterial eye infections and prevention of post-surgical eye infections. It is effective against both gram-positive and gram-negative bacteria.
Indications
- Bacterial eye infections (conjunctivitis, blepharitis)
- Prevention of post-surgical eye infections
Pharmacology
Bacitracin inhibits bacterial cell wall peptidoglycan synthesis and is active against gram-positive bacteria (staphylococci, streptococci, corynebacteria, clostridia) and some gram-negative species (Neisseria and Haemophilus influenzae).
Polymyxin B binds to membrane phospholipids, disrupting the bacterial cytoplasmic membrane of most gram-negative organisms, allowing leakage of intracellular constituents.
