Neosporin (Neomycin/Polymyxin B/Bacitracin ) Eye Ointment

Neosporin general information

What is Neosporin used for?

Neosporin Ophthalmic Ointment is used to treat bacterial infections of the external surface of the eye and its adnexa, which includes the eyelids and lachrymal apparatus (tear ducts and glands).  These infections include: conjunctivitis, which is inflammation of the conjunctiva (outermost layer of the eye and the inside of the eyelid); blepharitis or inflammation of the eyelid; keratitis which is inflammation of the cornea (the clear area at the front of the eye over the lens and pupil); blepharoconjunctivitis which is inflammation of the conjunctiva and the eyelid; keratoconjunctivitis which is inflammation of the conjunctiva and cornea.  Neosporin Ophthalmic Ointment helps relieve symptoms of eye infection including sore eyes, redness, inflammation, discharge and crusting around the eyelid.  

How does Neosporin work?

Neosporin Ophthalmic Ointment contains a combination of three antibiotics that are used to treat bacterial infections of the external surface of the eye.  Neomycin in Neosporin Ophthalmic Ointment is a broad-spectrum aminoglycoside antibiotic that is used in topical medications and is effective against wide range of bacteria found in infected skin, including Staphylococcus, Pseudomonas and Proteus species, and works by blocking bacterial protein synthesis and inhibiting the production of proteins needed for bacterial cell growth.  The antibiotic Polymyxin in Neosporin Ophthalmic Ointment is only effective Gram negative bacteria like Pseudomonas aeruginosa and Escherichia coli, and is often used in combination with other antibiotics for topical bacterial infection.  It works by disrupting the bacterial cell membrane, which makes it more permeable and the bacteria more susceptible to the effects of other antibiotics.  Bacitracin in Neosporin Ophthalmic Ointment is a broad-spectrum antibiotic that is also used in combination with other antibiotics for topical bacterial infection.  It works by disrupting the bacterial cell wall and interfering with bacterial cell wall synthesis.  Polymyxin B and neomycin together are active against Staphylococcus aureus, Escherichia coli, Haemophilus influenzae, Klebsiella-Enterobacter species, Neisseria species and Pseudomonas aeruginosa.  Bacitracin is active against most Gram-positive bacteria, pathogenic Neisseria species and Haemophilus influenzae.
