Which drug class treats eye infections?

• A. Otic Preparations
• B. Platelet Inhibitor
• C. Smoking Deterrent
• D. Ophthalmic Anti-Infective

Answer: (D)

Eye infections are treated with drugs designed to act locally on the eye. Medicines in the ophthalmic anti-infective class are formulated as eye drops or ointments, so they reach the ocular tissues directly and in high local concentrations, while minimizing systemic exposure. This targeted approach makes them the appropriate choice for conjunctivitis, keratitis, and other ocular infections, because you want a drug that treats the infection right at its site of action.

The other options don’t fit because they refer to areas or purposes unrelated to the eye: otic preparations are for ear conditions, platelet inhibitors affect blood clotting, and smoking deterrents aid in smoking cessation. Hence, ophthalmic anti-infectives are the drug class specifically used to treat eye infections.
