Tobradex is a combination ophthalmic preparation. Which two active ingredients does it contain?

• A. Tobramycin and Dexamethasone
• B. Neomycin and Hydrocortisone
• C. Amoxicillin and Clavulanic acid
• D. Ofloxacin and Prednisolone

Answer: (A)

The idea behind Tobradex is to treat both infection and inflammation in one eye drop. It combines an antibiotic with a corticosteroid, so you tackle the bacteria causing the infection and also reduce the inflammatory response that can damage ocular tissues and cause pain and redness.

Tobramycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis, helping to kill or stop the growth of many eye pathogens. Dexamethasone is a potent corticosteroid that lowers inflammation by reducing the production of inflammatory mediators and limiting immune cell activity. Together, they provide both antimicrobial action and anti-inflammatory relief, which is why this combination is used for inflammatory eye conditions where infection is a concern.

The other options mix different antibiotics and steroids that are not the Tobradex formulation, so they don’t represent this specific Tobradex combination.
