Which of the following drugs is classified as a Schedule V drug?

Pregabalin is classified as a Schedule V controlled substance under the Controlled Substances Act. Schedule V drugs are those that have a lower potential for abuse relative to Schedule IV drugs and are generally recognized as having accepted medical uses. The criteria for this classification include the drug's medical utility, potential for addiction, and the necessity for regulation to prevent misuse.

Pregabalin is primarily used for the management of neuropathic pain, fibromyalgia, and as an adjunct therapy for seizures. Its classification as Schedule V reflects an acknowledgment that while it does have some potential for misuse, the risk is considerably lower than that associated with drugs in higher schedules, such as Schedule II or III.

In contrast, drugs like hydrocodone, oxycodone, and fentanyl are classified as Schedule II substances due to their higher potential for abuse and addiction, as well as their limited medicinal use compared to Schedule V substances. This distinction is critical in pharmacy practice, as it impacts prescribing, dispensing, and monitoring requirements for these medications. Understanding these classifications is essential for ensuring patient safety and adhering to legal guidelines in pharmacy practice.
