Alfentanil is classified as which Schedule?

• A. Schedule III
• B. Schedule II
• C. Schedule IV
• D. Schedule I

Answer: (B)

Alfentanil is a potent synthetic opioid used in anesthesia, and its classification reflects both a high potential for abuse and an accepted medical use under strict controls. That combination places it in Schedule II. Schedule II substances have recognized medical uses but require strict prescribing rules, no refills, and enhanced recordkeeping and DEA oversight. This differs from substances in lower schedules with lower abuse potential and looser restrictions, and from Schedule I, which has no accepted medical use.
