**Core Concept**
Naloxone, naltrexone, and activated charcoal are commonly used in the management of heroin (diacetylmorphine) poisoning, which is a medical emergency caused by opioid overdose. Heroin is a potent opioid agonist that can lead to respiratory depression, coma, and even death.

**Why the Correct Answer is Right**
Heroin poisoning is typically managed with opioid antagonists like naloxone, which reverses respiratory depression and coma. Naloxone works by competitively inhibiting opioid receptors in the central nervous system, specifically the mu-opioid receptors. This reverses the effects of heroin, allowing patients to breathe normally again. Activated charcoal is used to prevent further absorption of the drug from the gastrointestinal tract. Naltrexone is another opioid antagonist that can be used to manage opioid dependence and withdrawal.

**Clinical Pearl / High-Yield Fact**
A notable fact about heroin poisoning is that naloxone's effects are short-lived, lasting around 30-60 minutes, which is why repeated doses may be necessary to maintain reversal of opioid effects.
