  1. 治理痛症藥物新趨勢 香港醫院藥劑師學會 藥物教育資源中心教育總監 崔俊明藥劑師

  2. 點解香港人咁忍得?

  3. 止痛藥種類 • 鴉片類 • 非類固醇消炎止痛藥﹝NSAIDs﹞ • Acetaminophen / Paracetamol(撲熱息痛):市面上最常用的非處方止痛藥

  4. 止痛藥分解速度影響藥力吸收速度 • Davis SS, Hardy JG. Drug delivery in the gastrointestinal tract. In: Kumar D, Gustavson F, eds. An illustrated guide to gastrointestinal motility. Chichester: John Wiley, 1988: 265–70.

  5. Acetaminophen / Paracetamol新配方 • 新配方快速在胃內將止痛藥成份分解,分解速度比原有配方的Acetaminophen / Paracetamol 止痛藥高達5倍 • 新配方的創新藥物輸送系統幫助迅速起效,令止痛藥成份比一般止痛藥停留在胃部的時間較短 • 藥力發揮功效後,新配方的Acetaminophen / Paracetamol止痛藥代謝物會經尿液自然排出體外 須依照指示使用

  6. Acetaminophen / Paracetamol新配方 1. US Food and Drug Administration. Food additive status list. July 2006. Accessed at http://www.cfsan.fda.gov/~acrobat/opa-appa.pdf Accessed on 03 April 2008. 成份: • 褐藻酸 (Alginic Acid) • 來自海帶 • 廣泛應用於食品科學 • 碳酸鈣 (Calcium Carbonate) • 廣泛用於輔料 • 成為某些制酸劑的有效成分

  7. 新配方的Acetaminophen / Paracetamol 如何發揮效用? 褐藻酸  (Alginic Acid) 親水性的特質把胃液引至糖衣錠, 褐藻酸因而膨脹並分解藥丸 • 碳酸鈣 • (Calcium Carbonate) 與胃酸產生反應釋放二氧化碳, 因而分解糖衣錠

  8. Acetaminophen / Paracetamol兩種配方分解速度比較 普通Acetaminophen Acetaminophen 新配方 • Wilson C et al. Abstract PH 217, International Association for the Study of Pain 12th World Congress on Pain, Glasgow 17–22 August 2008.

  9. Acetaminophen / Paracetamol 新配方 使用範圍 • 喉嚨痛1 • 頭痛2 • 感冒引致的肌肉痠痛3 • 偏頭痛4 • 經痛5,6 • 牙痛7,8 • 肌胳痛9 • 骨關節痛10,11 • 發燒12 • Coulthard P, et al. Br Dent J 2001;191:319–24. • Moller PL, et al. J Clin Pharmacol 2000;40:370–8. • Wade AG, Ward PJ. Curr Med Res Opin. 1982;8:191–6. • Zhang W, et al. Ann Rheum Dis 2004;63:901–7. • Pincus T, et al. Ann Rheum Dis 2002;63:931–9. • Bachert C, et al. Clin Ther 2005;27:993–1003. Thomas M, et al. Br J Gen Pract 2000;50:817–20. Prior MJ, et al. Cephalagia 2002;22:740–8. Loose I, Winkel M. Arznelmittelforschung 2004;54:513–21. Lipton RB, et al. Arch Intern Med 2000;160:3486–92. Milsom I, et al. Clin Ther 2002;24:1384–400. Ali Z, et al. Curr Med Res Opin 2007;23:841–51.

  10. 實踐「身體為先」生活態度 • 每個人都應該以「身體為先」,照顧自己的身體及適時回應身體發出的健康訊號和徵兆 • 實踐「身體為先」應由微小處入手,以治理頭痛為例: • 非藥物治理方法: • 休息 • 改變生活模式(減壓)/ 學習放鬆 • 運動 • 按摩 • 均衡飲食 • 藥物治理方法: • 對於輕度及急性頭痛,可以服用非處方止痛藥來暫緩痛症,作自我管理 • 選擇一隻安全性高及治療效果佳的止痛藥來治理痛症 • 若痛症持續,應諮詢家庭醫生或藥劑師的意見
