Which drug is an example of a Schedule IV drug?

Alprazolam is classified as a Schedule IV controlled substance, indicating that it has a lower potential for abuse relative to drugs in Schedules I-III but still carries a risk of dependence and has accepted medical uses. Schedule IV drugs are defined by their therapeutic benefits as well as their potential for abuse, and alprazolam is commonly prescribed for the management of anxiety and panic disorders.

Other choices represent substances with different classifications. Hydromorphone is an opioid analgesic in Schedule II due to its higher potential for abuse and addiction. Methylphenidate, used for ADHD, is classified as a Schedule II drug as well, reflecting its potential for misuse and dependence. Marinol, a specific formulation of THC, is classified under Schedule III, recognizing its lower abuse potential compared to the more tightly controlled substances.

By understanding the classifications, particularly for alprazolam, it's clear how the regulatory framework for controlled substances evaluates the balance between medical utility and potential for abuse.
