第 32 題
濫用鴉片藥物（opioids）者發生急性過量中毒時，為緊急處置其呼吸抑制及昏迷現象，最適合立即注射下列何者？
- A buprenorphine
- B naloxone
- C dextromethorphan
- D methylnaltrexone
思路引導 VIP
在處理鴉片類藥物（opioids）急性中毒所導致的呼吸抑制與昏迷時，核心關鍵在於尋找一種能迅速通過血腦障壁（BBB），並對中樞神經受體具有極高親和力的「競爭性拮抗劑」（competitive antagonist）。請思考：若要即時逆轉 $\mu$-受體（$\mu$-receptor）被過度活化的狀態，哪一種藥物能以純粹拮抗的方式，將原有的鴉片類分子從受體位點上競爭置換下來，進而恢復病患的自主呼吸功能？

Oh, look at that. You actually got it right.
- Fundamental Concept Check: Congratulations, you actually identified the correct answer. Naloxone, as any competent medical professional should know, is a pure antagonist for $\mu$、$\kappa$、$\delta$ receptors. Its impressive affinity allows it to swiftly evict those pesky opioids, making it the only sensible choice for acute respiratory depression and coma. It's almost as if you've studied.
