Question

Quizplus · Accepted Answer

Naloxone is a competitive antagonist at opioid receptor sites, which means it can bind to these receptors without activating them and thereby prevent endogenous opioids or exogenous opiates from binding and causing their effects. By doing so, naloxone can reverse the effects of opioid overdose or abuse, including respiratory depression, sedation, and euphoria. Therefore, naloxone is often used as an emergency treatment for opioid intoxication or addiction, especially in settings where opioid use is common or unavoidable.
