According to the Code of Federal Regulations, which of the following medications is a Schedule II controlled substance?

Rationale

Methadone is classified as a Schedule II controlled substance.

Methadone is recognized for its potential for abuse and dependence, which necessitates strict regulation under the Controlled Substances Act. As a Schedule II drug, it is legally prescribed but heavily monitored due to its use in pain management and opioid addiction treatment.

A (Metoprolol) YOUR ANSWER

Metoprolol is a beta-blocker used primarily for treating hypertension and heart-related conditions. It is not classified as a controlled substance, as it does not have a high potential for abuse or dependency, making it a Schedule IV or V drug instead.

B (Methadone) CORRECT

As a powerful opioid analgesic, methadone is classified under Schedule II due to its high potential for abuse and risk of severe psychological or physical dependence. It is commonly used in opioid addiction treatment programs and requires careful prescription practices.

C (Metformin) YOUR ANSWER

Metformin is an oral medication primarily used to manage type 2 diabetes and is not associated with abuse potential. Therefore, it is not classified as a controlled substance at all, as it does not pose significant risk for dependence.

D (Methotrexate) YOUR ANSWER

Methotrexate is an antimetabolite and anti-inflammatory drug used for conditions such as cancer and autoimmune diseases. Despite its serious side effects, it is not classified as a controlled substance, as it does not have an abuse potential like substances in Schedule II.

Conclusion

Controlled substances are categorized based on their potential for abuse and dependency, with Schedule II substances like methadone requiring stringent regulations. In this context, methadone stands out as the only choice among the options that meets the criteria for Schedule II classification, highlighting the importance of proper management and oversight in its prescription and use.
