Final answer:
Lofexidine is the alpha 2 adrenergic agonist used to alleviate withdrawal symptoms in individuals stopping opioid use completely, making option C) Lofexidine the correct answer.
Step-by-step explanation:
Lofexidine is an alpha 2 adrenergic agonist used to help alleviate withdrawal symptoms for individuals who are discontinuing opioid use. Unlike methadone or buprenorphine, which are opioid agonists used to reduce cravings and withdrawal effects, lofexidine is not an opioid and does not provide any analgesic or euphoric effects. Its role is specific to withdrawal symptom management, making it a favorable option for those seeking to stop opioid use completely without substituting another opioid. Therefore, the correct answer to the statement is C) Lofexidine. Other medications mentioned like gabapentin and naloxone have different uses in the context of opioid addiction; gabapentin, for neuropathic pain, and naloxone, as an opioid antagonist, used to reverse opioid overdose.
