Which class of controlled substances includes substances like BZDs and sleep aids?

The correct classification for substances like benzodiazepines (BZDs) and sleep aids is Class C4. This category includes drugs that have a lower potential for abuse compared to classes C1 through C3, but still may lead to psychological or physical dependence. Benzodiazepines are commonly prescribed for anxiety, insomnia, and other conditions due to their sedative effects and ability to enhance the action of the neurotransmitter GABA.

Class C4 is specifically designed to encompass substances that are widely used in clinical practice but must still be regulated due to their potential for misuse and dependence. Common examples include medications such as diazepam, lorazepam, and certain sleep aids like zolpidem. The scheduling reflects the balance between the therapeutic benefits of these medications and the risks associated with their abuse.

Understanding the categorization of controlled substances is essential for safe medication dispensing and adhering to legal regulations regarding prescriptions and usage in pharmacy practice.
