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

• A. Alprazolam
• B. Ibuprofen
• C. Acetaminophen
• D. Amoxicillin

Answer: (A)

The main concept is understanding how drugs are placed into scheduled categories under the Controlled Substances Act. Schedule IV includes medications that have an accepted medical use but a lower potential for abuse and dependence than higher schedules, though dependence can still occur.

Alprazolam, a benzodiazepine, fits this category: it has well-established medical uses for anxiety and panic disorders, but it also carries a risk of physical and psychological dependence, which keeps it in Schedule IV. The other drugs listed are not controlled substances: ibuprofen is a nonprescription NSAID, acetaminophen is a common analgesic/antipyretic, and amoxicillin is an antibiotic.
