How is naltrexone classified in the treatment of OUD?

Naltrexone is classified as an opioid antagonist in the treatment of Opioid Use Disorder (OUD). As an opioid antagonist, it works by binding to the opioid receptors in the brain without activating them, effectively blocking the effects of any opioids that may be taken. This mechanism helps to reduce cravings and the reinforcing effects associated with opioid use.

By preventing opioids from exerting their effects, naltrexone can assist individuals in staying abstinent from opioid use. It is important to highlight that naltrexone is used as part of a comprehensive treatment plan, which may include counseling and support services.

A co-analgesic refers to medications that are not primarily designed to treat pain but can aid in pain management; naltrexone does not fit this role either. Lastly, short-acting opioids refer to substances that provide immediate, short-term effects, which contrasts with naltrexone's purpose of blocking opioid effects altogether. Thus, the classification of naltrexone as an opioid antagonist is crucial for its
