Abstract
Buprenorphine (BUP)是一種是半合成的鴉片生物鹼之衍生物,在台灣隸屬於第三級管制藥品,為μ鴉片受體之部份激動劑,也是κ鴉片受體之拮抗劑,因此同時具有致效劑及拮抗劑的特性,目前在市面上有高劑量的用途為鴉片類物質成癮替代療法,以及低劑量作為中、重度疼痛的止痛劑,由於buprenorphine具有廣泛的首渡代謝,導致口服生體可用率差,因此開發buprenorphine舌下膜劑 (sublingual film)處方,並期許提高其生體可用率。
本研究之舌下膜劑處方使用solvent casting method製備,並使用PVP K30、gelatin和corn starch作成膜聚合物,並測試了不同的促進滲透劑,如:Capryol 90®、Capryol PGMC®和Labrasol®。本實驗藉由建立單層膜及雙層膜的舌下膜劑型平台,其中雙層構造包括黏合層和背襯層,背襯層向治療部位提供單向藥物遞送。除了評估舌下膜劑處方的物理特徵,如:外觀、藥物含量、重量和厚度之均勻性之外,也評估了體外藥物釋放研究和兔子之體內藥物動力學研究。
含有促進滲透劑的單層舌下膜劑處方和雙層設計的舌下膜劑處方在溶離結果顯示有較快的溶離速度,而兔子之體內藥物動力學研究研究顯示,與市售sublingual tablet (Temgesic®)相比,本實驗之舌下膜劑處方Tmax值較低,且 血中濃度Cmax增加,優化之舌下膜劑處方 (BB F005 Labrasol)的相對生體可用率最高可增加7.2倍。
我們的研究結果指出,本研究成功地開發單層和雙層結構之buprenorphine舌下膜劑處方,與市售sublingual tablet (Temgesic®)相比,可以提高buprenorphine的生體可用率,並可以加快藥物起效時間,本研究對於開發buprenorphine劑型處方已有進一步發展。
