Which medication is in Schedule II and contains hydrocodone?

Hycodan is the correct choice because it is a combination medication that contains hydrocodone and is classified as a Schedule II controlled substance. Hydrocodone is an opioid analgesic widely recognized for its pain-relieving properties, and due to its potential for abuse and addiction, medications containing hydrocodone are strictly regulated under the Controlled Substances Act.

The other medications listed are classified differently. Percodan contains oxycodone, which is also a Schedule II substance but not hydrocodone. Duragesic, a transdermal patch, contains fentanyl and is also in Schedule II but is again separate from hydrocodone. Ativan, on the other hand, is a benzodiazepine (lorazepam) and is classified under Schedule IV, which indicates it has a lower potential for abuse compared to Schedule II substances.

Thus, Hycodan specifically represents the combination of hydrocodone and falls into the appropriate scheduling due to the specific opioid content it contains.
