Narcan is which pharmacologic class?

Explanation:
Narcan (naloxone) acts by binding to opioid receptors and blocking their activation by opioids. It has high affinity for μ-opioid receptors but produces no intrinsic effect, so it reverses opioid toxicity by preventing opioids from triggering their usual effects. That makes it an antagonist. While it can compete with opioids for the same receptor site and displace them, its essential pharmacologic class is antagonist rather than an agonist or a partial agonist.
