Which of the following is an antibiotic eye drop?

• A. Ciprofloxacin
• B. Prednisone
• C. Latanoprost
• D. Timolol

Answer: (A)

An antibiotic eye drop is used to treat eye infections by killing bacteria or stopping their growth. Ciprofloxacin is a fluoroquinolone antibiotic formulated for the eye; it works by inhibiting bacterial enzymes needed for DNA replication, which stops bacteria from multiplying and helps clear the infection. The other medications have different purposes: prednisone is a corticosteroid that reduces inflammation, latanoprost lowers intraocular pressure by increasing fluid outflow, and timolol also lowers eye pressure but by reducing fluid production. None of those treat bacterial infections, which is why ciprofloxacin is the antibiotic option.
