Which drug is categorized as Sedative/Tranquilizer (Controlled)?

• A. Acepromazine
• B. Alprazolam (Xanax)
• C. Trazodone
• D. Gabapentin

Answer: (B)

This question is about recognizing a controlled-substance that functions as a sedative/tranquilizer. Alprazolam is a benzodiazepine, a class that provides calming effects, anxiety relief, and muscle relaxation. Because benzodiazepines have potential for dependence and misuse, they are regulated as controlled substances (Schedule IV in the U.S.). In veterinary settings, this means strict handling, logging, and prescription controls.

Acepromazine is a tranquilizer used for pre-anesthetic sedation but is not a controlled substance. Trazodone and gabapentin are used for anxiety or pain but are not generally classified as controlled substances, so they aren’t in the same category of Sedative/Tranquilizer (Controlled).
