Which of the following drug is NOT used in the treatment of heroin dependence?
**Core Concept**
Heroin dependence is a complex condition requiring multi-faceted treatment approaches. Medications like methadone, buprenorphine, and naltrexone are used to manage withdrawal symptoms, cravings, and relapse prevention.
**Why the Correct Answer is Right**
The correct answer is not used in the treatment of heroin dependence because it does not address the opioid withdrawal or craving symptoms effectively. Heroin dependence treatment focuses on medications that either replace the opioid (methadone, buprenorphine) or block its effects (naltrexone). The correct answer does not belong to this category.

* It is often used for relapse prevention and can be used in combination with other medications.
**Option C:**
