Which is an example of a controlled substance?

Oxycodone is an example of a controlled substance because it is classified as a Schedule II drug under the Controlled Substances Act. This classification indicates that oxycodone has a high potential for abuse, which can lead to severe psychological or physical dependence. Controlled substances are regulated by law due to their potential for abuse and are subject to specific legal requirements regarding prescribing, dispensing, and documentation.

In contrast, ibuprofen and amoxicillin are not controlled substances; ibuprofen is an over-the-counter nonsteroidal anti-inflammatory drug (NSAID) and amoxicillin is an antibiotic that is also not classified as a controlled substance. Hydroxyzine, while a prescription medication, is categorized as an antihistamine and is classified as a non-controlled substance. Understanding these classifications is critical for anyone involved in pharmacy practice, as it affects how medications are handled and dispensed.
