Which of the following is an example of a CII controlled substance?

• A. Codeine
• B. Zolpidem
• C. Oxycodone
• D. Lyrica

Answer: (C)

Oxycodone is classified as a CII controlled substance due to its high potential for abuse and the risk of severe psychological or physical dependence. The classification system for controlled substances in the United States places drugs into schedules based on their accepted medical uses, potential for abuse, and safety or dependence liability.

As a CII substance, oxycodone is recognized for its use as a powerful pain reliever but is strictly regulated to prevent misuse. It is subject to stringent prescribing and dispensing requirements compared to lower-scheduled substances, reflecting the serious nature of its potential for addiction and abuse.

Codeine, although also used in pain management, can vary in scheduling depending on its formulation and concentration; it may not always be classified as a CII. Zolpidem, primarily used for treating insomnia, is classified as a CIV, which indicates lower potential for abuse. Lyrica, used for neuropathic pain and seizures, is classified as a CV, reflecting its even lower risk. Thus, oxycodone is the correct answer representing a CII controlled substance.
