芬太尼-當前最具威脅性的毒品

from 三瘋資料庫 · host 一天瘋三次

來源深入探討了芬太尼（Fentanyl）的解剖學與生理學機制，說明其為何成為當前最具威脅性的藥物。芬太尼作為一種全合成鴉片類物質，其藥效遠超海洛因與嗎啡，能與大腦及脊髓中的μ-鴉片受體強力結合，進而阻斷痛覺傳導。然而，由於控制呼吸的腦幹區域也存在相同的受體，極小劑量的過量便會引發致命的呼吸抑制，導致極窄的治療窗口。文中也區分了天然鴉片與合成鴉片類藥物的差異，並詳述了人體自身的內源性鴉片系統如何運作。最後，內容強調了納洛酮（Naloxone）在急救中的作用，以及長期服用藥物所產生的耐藥性與成癮性對生命的嚴重威脅。 -- Hosting provided by SoundOn
