Polymyxin B Sulfate is the sulfate salt of polymyxin B1 and B2 which are produced by the growth of Bacillus polymyxa (Prazmowski) Migula (Fam. Bacillaceae). It has a potency of not less than 6,000 polymyxin B units per milligram, calculated on an anhydrous basis. The structural formulae are:

Gramicidin (also called gramicidin D) is a mixture of three pairs of antibacterial substances (Gramicidin A, B and C) produced by the growth of Bacillus brevis Dubos (Fam. Bacillaceae). It has a potency of not less than 900 mcg of standard gramicidin per mg. The structural formulae are:

A wide range of antibacterial action is provided by the overlapping spectra of neomycin, polymyxin B sulfate, and gramicidin.

Neomycin is bactericidal for many gram-positive and gram-negative organisms. It is an aminoglycoside antibiotic which inhibits protein synthesis by binding with ribosomal RNA and causing misreading of the bacterial genetic code.

Polymyxin B is bactericidal for a variety of gram-negative organisms. It increases the permeability of the bacterial cell membrane by interacting with the phospholipid components of the membrane.

Gramicidin is bactericidal for a variety of gram-positive organisms. It increases the permeability of the bacterial cell membrane to inorganic cations by forming a network of channels through the normal lipid bilayer of the membrane.

Neomycin and polymyxin B sulfates and gramicidin ophthalmic solution is indicated for the topical treatment of superficial infections of the external eye and its adnexa caused by susceptible bacteria. Such infections encompass conjunctivitis, keratitis and keratoconjunctivitis, blepharitis and blepharoconjunctivitis.

This product is contraindicated in those persons who have shown hypersensitivity to any of its components.

NOT FOR INJECTION INTO THE EYE. This product should never be directly introduced into the anterior chamber of the eye or injected subconjunctivally.

Topical antibiotics, particularly neomycin sulfate, may cause cutaneous sensitization. A precise incidence of hypersensitivity reactions (primarily skin rash) due to topical antibiotics is not known.

The manifestations of sensitization to topical antibiotics are usually itching, reddening and edema of the conjunctiva and eyelid. A sensitization reaction may manifest simply as a failure to heal. During long-term use of topical antibiotic products, periodic examination for such signs is advisable, and the patient should be told to discontinue the product if they are observed. Symptoms usually subside quickly on withdrawing the medication. Applications of products containing these ingredients should be avoided for the patient thereafter. (See PRECAUTIONS:General).
