Which medication can reverse opioid-induced sedation in patients?

Naloxone is the medication that can reverse opioid-induced sedation because it is an opioid antagonist. It works by competitively binding to the same receptors in the brain that opioids target, effectively displacing them and reversing their effects. In the case of opioid overdose, where sedation can lead to respiratory depression and even coma, naloxone can help restore breathing and consciousness by inhibiting the action of opioids.

In contrast, adrenaline is primarily used for cardiac situations and does not reverse the central nervous system effects of opioids. Flumazenil is a benzodiazepine antagonist, which would not affect opioid-induced effects as it targets a different class of medications. Atropine is used for bradycardia and is not relevant to reversing opioid effects either. Thus, naloxone's specific action on opioid receptors makes it the appropriate intervention for reversing sedation caused by opioids.
