Which of the following is a controlled substance?

Rationale

Butorphanol is a controlled substance.

Butorphanol is classified as a controlled substance due to its potential for abuse and dependence, particularly as it is an opioid agonist-antagonist used for pain management. This classification is regulated to ensure its safe use and to prevent misuse.

A (Metoprolol) YOUR ANSWER

Metoprolol is a beta-blocker primarily used to treat high blood pressure and heart-related issues. It does not have any properties that warrant its classification as a controlled substance, as it has a low potential for abuse and is not associated with dependency.

B (Butorphanol) CORRECT

As noted, butorphanol is an opioid medication that can lead to physical dependence and has abuse potential, which necessitates its classification as a controlled substance. Its effects on the central nervous system and potential for misuse are the reasons behind its regulation.

C (Carvedilol) YOUR ANSWER

Carvedilol is another beta-blocker similar to metoprolol, used to treat heart failure and hypertension. Like metoprolol, it does not possess addictive properties or a potential for abuse, thus it is not classified as a controlled substance.

D (Propranolol) YOUR ANSWER

Propranolol is also a beta-blocker used to treat various conditions including anxiety and hypertension. It shares the same safety profile as metoprolol and carvedilol, lacking the characteristics that would classify it as a controlled substance.

Conclusion

Among the options provided, butorphanol stands out as a controlled substance due to its opioid properties and potential for abuse. In contrast, metoprolol, carvedilol, and propranolol are beta-blockers with no significant risk of addiction or abuse, thus not requiring control under drug regulation laws. Understanding these classifications is crucial for safe prescribing practices and awareness of medication risks.
