Which of the following is an approved treatment for narcotic dependence?

Methadone is an approved treatment for narcotic dependence because it is a long-acting opioid that helps manage withdrawal symptoms and cravings associated with opioid addiction. It works by acting on the same receptors in the brain as other opioids, providing relief without producing the same euphoric high, which reduces the potential for misuse. Methadone maintenance therapy is often part of a comprehensive treatment plan that includes counseling and support services, making it effective in promoting recovery and stability in individuals with opioid dependence.

In contrast, other options like oxycodone, codeine, and fentanyl are not recommended for treating narcotic dependence. They are primarily used for pain management and can contribute to the cycle of addiction due to their high potential for abuse and dependence.
