polymyxin b sulfate + bacitracin zinc + neomycin

Polymyxin b sulfate + bacitracin zinc + neomycin is a **topical ophthalmic triple-antibiotic combination** used for the treatment of superficial bacterial infections of the external eye and its adnexa, including conjunctivitis, keratitis, keratoconjunctivitis, blepharitis, and blepharoconjunctivitis caused by susceptible organisms. The ointment combines three small-molecule antibiotics with complementary antibacterial spectra: polymyxin B disrupts the cell membrane of susceptible gram-negative bacteria, neomycin is an aminoglycoside that inhibits bacterial protein synthesis, and bacitracin inhibits bacterial cell wall synthesis with primary activity against gram-positive organisms. It has been marketed as ophthalmic ointment products including Neo-Polycin and Neomycin and Polymyxin B Sulfates and Bacitracin Zinc Ophthalmic Ointment, and the provided context identifies Bausch & Lomb as a developer/marketer.
