Which of the following drugs is listed as Schedule IV in the material?

• A. Amoxicillin
• B. Diazepam
• C. Alprazolam
• D. Flurazepam

Answer: (D)

Schedule IV drugs have medical use and a relatively low potential for abuse compared with drugs in higher schedules; many benzodiazepines fall into this category due to their therapeutic roles and the level of risk they pose. Flurazepam is a benzodiazepine hypnotic used to treat insomnia, and in the material you’re studying it is listed as Schedule IV. That positioning reflects its accepted medical use alongside a lower relative abuse potential. Amoxicillin isn’t a controlled substance at all, so it isn’t scheduled. The other benzodiazepines listed are not designated Schedule IV in this material, which is why Flurazepam is the correct choice in this context.
