All You Need to Know About Neomycin and Polymyxin B Sulfates for Eyes

Neomycin and Polymyxin B Sulfates are two antibiotics used to fight bacterial infections of the eye. Neomycin is a broad-spectrum antibiotic that can kill many types of bacteria, while Polymyxin B sulfate is effective against Gram-negative bacteria.

How Do They Work?

Neomycin works by interfering with the bacteria's ability to make proteins. This prevents the bacteria from multiplying and spreading.

Polymyxin B sulfate works by damaging the bacteria's cell membrane, causing the cell to leak its contents and die.
