Sterile Veterinary Ophthalmic Ointment


TriOptic-P Caution

Federal law restricts this drug to use by or on the order of a licensed veterinarian.


Each gram contains bacitracin zinc 400 units, neomycin sulfate 5 mg (equivalent to 3.5 mg of neomycin base), polymyxin B sulfate 10,000 units, in a base of white petrolatum and mineral oil.

ACTIONS: The 3 antibiotics present in TriOptic-P Veterinary Ophthalmic Ointment provide a broad spectrum of activity against the gram-positive and gram-negative bacteria commonly involved in superficial infections of the eyelid and conjunctiva. Bacitracin is effective against gram-positive bacteria including hemolytic and non-hemolytic Streptococci and Staphylococci. Resistant strains rarely develop. Neomycin is effective against both gram-positive and gram-negative bacteria including Staphylococci, Escherichia coli, Haemophilus influenzae, and many strains of Proteus and Pseudomonas. Polymyxin B is bactericidal to gram-negative bacteria especially Pseudomonas. No resistant strains have been found to develop in vivo.

TriOptic-P Indications

In the treatment of superficial bacterial infections of the eyelid and conjunctiva in dogs and cats when due to organisms susceptible to the antibiotics contained in the ointment. Laboratory tests should be conducted including in vitro culturing and susceptibility tests on samples collected prior to treatment.

As with any antibiotic preparation, prolonged use may result in the overgrowth of nonsusceptible organisms including fungi. Appropriate measures should be taken if this occurs. If infection does not respond to treatment in 2 or 3 days, the diagnosis and therapy should be reevaluated.
