What is the primary purpose of Naloxone?

• A. To sedate the patient
• B. To treat hypertension
• C. Reverse respiratory depression by blocking opioid receptors
• D. To relieve pain

Answer: (C)

Naloxone is an opioid antagonist used to reverse life-threatening respiratory depression caused by opioid overdose. It works by binding to opioid receptors in the brain, displacing the opioid molecules that are causing slowed or stopped breathing, and thereby restoring normal respiratory drive and consciousness. This is why it’s the best answer: it directly counteracts the effects of opioids, rather than sedating, lowering blood pressure, or relieving pain. In real cases, it may precipitate withdrawal in opioid-dependent individuals and its effects can wear off, so monitoring and repeating dosing if needed are important.
