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

• A. Eszopiclone
• B. Zaleplon
• C. Temazepam
• D. Lisdexamfetamine

Answer: (A)

Scheduling controls place substances in groups based on medical use and potential for abuse. Schedule IV drugs have accepted medical uses and a relatively lower abuse potential compared with higher schedules, with the possibility of limited physical or psychological dependence.

Eszopiclone is a non-benzodiazepine hypnotic used to treat insomnia and is listed as Schedule IV. This reflects its medical use and comparatively lower risk of abuse relative to drugs in higher schedules. For context, other sleep medications in this area, like zaleplon and temazepam, are also placed in Schedule IV in standard classifications, while lisdexamfetamine is a Schedule II stimulant with higher abuse potential. The material identifies eszopiclone as Schedule IV, which is why it’s the correct entry in this context.
