Pharmacology
Bacitracin: Inhibits bacterial cell wall synthesis by preventing transfer of mucopeptides into the growing cell wall.
Neomycin: Interferes with bacterial protein synthesis by binding to 30S ribosomal subunits.
Polymyxin B: Binds to phospholipids, alters permeability, and damages the bacterial cytoplasmic membrane permitting leakage of intracellular constituents.
Contraindications
Hypersensitivity to neomycin, polymyxin B, bacitracin, or any component of the formulation
Administration

Warnings/Precautions
Concerns related to adverse effects:
• Neomycin sensitization: Neomycin may cause cutaneous sensitization. Symptoms of neomycin sensitization include itching, reddening, edema, and failure to heal. Discontinuation of product and avoidance of similar products should be considered.
• Ocular effects: May retard corneal wound healing.
• Superinfection: Prolonged use may lead to overgrowth of nonsusceptible organisms, including fungi. If superinfection is suspected, institute appropriate alternative therapy.
Other warnings/precautions:
• Appropriate use: For topical ophthalmic use only. Do not introduce directly into anterior chamber of the eye. Inadvertent contamination of multiple-dose ophthalmic tube tip has caused bacterial keratitis.
