What is typically included in Schedule IV drugs?

Schedule IV drugs are characterized as having a lower potential for abuse relative to substances in schedules I through III, and they are generally accepted for medical use in the United States. Tramadol is classified in this category due to its lower likelihood of causing dependence and its approved medical applications, primarily for pain management.

The other substances listed are classified differently: Hydrocodone is associated with higher potential for abuse and is classified as a Schedule II drug. Methadone, while used in specific treatment settings such as opioid addiction, is also classified as Schedule II because of its potential for abuse. Likewise, cocaine is classified as a Schedule II drug due to its stimulant effects and potential for addiction.

This context highlights how Tramadol's therapeutic uses and lower abuse potential place it squarely within Schedule IV, distinguishing it from the others listed.
