Which of the following is classified as a Schedule V (C5) drug?

1. Hydromorphone

2. Lacosamide

3. PCP

4. Buprenorphine

The correct answer is: Lacosamide

In the context of controlled substances, Schedule V (C5) drugs are substances that have a lower potential for abuse compared to Schedules I-IV, and they are typically used in medical treatment for conditions that require less potent analgesic effects and are less likely to lead to physical dependency. Lacosamide fits this classification as it is primarily used as an anticonvulsant for the treatment of epilepsy. It is recognized for having a lower potential for abuse. The other substances listed are classified differently due to their higher potential for abuse and addiction. For example, hydromorphone is classified as a Schedule II drug due to its strong opioid nature, which carries a significant risk for dependency. PCP (phencyclidine), a hallucinogen with a high potential for abuse, is classified as a Schedule I substance, while buprenorphine, although less potent than some opioids, is still a Schedule III medication, indicating that it has a higher abuse potential than Schedule V drugs. These classifications are crucial for understanding the legal and regulatory framework surrounding the prescription and dispensing of controlled substances.
