At a glance
Bacitracin Zinc + Neomycin Sulphate + Polymixin B Eye prep is a combination antibiotic used for the treatment of bacterial eye infections. It is effective against both gram-positive and gram-negative bacteria.
Indications
- Bacterial eye infections (blepharitis, conjunctivitis, keratitis)
- Post-operative infection prevention
- Neonatal eye infections
Pharmacology
Neomycin is an aminoglycoside antibiotic that binds to the 30S subunit of the bacterial ribosome, inhibiting protein synthesis and disrupting DNA synthesis. It is active against gram-negative aerobes and some strains of staphylococci.
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.
