Terramycin is composed of which ingredients?

• A. Oxytetracycline + Polymyxin B
• B. Gentamicin + Neomycin
• C. Ciprofloxacin + Dexamethasone
• D. Moxifloxacin + Polymyxin B

Answer: (A)

Terramycin is an ophthalmic antibiotic ointment that pairs a tetracycline with a polymyxin B. The active ingredients are oxytetracycline, which provides broad coverage against many gram-positive bacteria and some gram-negatives, and polymyxin B, which adds activity against gram-negative organisms by disrupting their membranes. This combination targets a range of bacteria commonly seen in equine ocular infections. The other listed options mix different antibiotics or include a steroid, so they do not match the Terramycin formulation. Therefore, the composition is oxytetracycline and polymyxin B.
