Final answer:
Methadone is the drug used to treat autonomic symptoms associated with heroin withdrawal.
Step-by-step explanation:
Methadone is the drug used to treat autonomic symptoms associated with heroin withdrawal. It is a synthetic opioid that is less euphorigenic than heroin and similar drugs. Methadone clinics help individuals struggling with opioid addiction manage withdrawal symptoms by using methadone. The drug used to treat autonomic symptoms associated with heroin withdrawal is primarily methadone. Methadone is a synthetic opioid that can alleviate the symptoms of opiate withdrawal by acting on the same opioid receptors as heroin does. However, methadone is less euphorigenic, meaning it produces fewer sensations of euphoria compared to heroin and is also used in regulated methadone clinics for opioid addiction treatment. Another medication that may be used is buprenorphine, which also serves to reduce withdrawal symptoms but has a lower risk of dependency. Furthermore, medications like clonidine, which is a sympatholytic drug, can be used to address autonomic symptoms related to anxiety, which can be a part of withdrawal. Clonidine works as an autonomic stabilizer by diminishing the sympathetic response that is often exacerbated during withdrawal.
