在本篇研究中，我們提出一種從市售藥物中回收其活性藥物成分（API）的方法，回收得到的API可經由配方加工重製為新產品；透過藥物再循環方案回收藥物中最重要成分–API，其步驟包括清洗、溶劑萃取及再結晶，本研究使用兩種API物作為示例，分別為：布洛芬（一種常用的抗炎藥）和普羅布考（一種抗高血脂藥物），首先，參考專利文獻，製備具有特定配方（API和賦形劑組成）的布洛芬和普羅布考藥物製劑，經過一系列的回收步驟，我們可從藥物製劑中分別成功回收63 w/w％ 的布洛芬及73 w/w％ 的普羅布考；其次，我們亦對市售布洛芬和普羅布考藥物進行測試，以確保我們所提出的方案亦可以應用於含有相同API但不同廠牌的藥物產品，即使賦形劑的含量和組成未知，根據實驗結果得知，使用相同的方法，市售的布洛芬和普羅布考分別成功地回收86 w/w％和73 w/w％。 此外，所有回收的API純度分析包含 FTIR、PXRD、DSC、UV-Vis光譜和 1H NMR等鑑定。;We proposed a method to recycle valuable active pharmaceutical ingredients (APIs) from various kind of medications, so later it could be re-formulated as a new product. In the drug recycle scheme, the most important component of the medication (the API) was recovered by drug recycle protocol which consisted of rinsing, solvent extraction, and recrystallization. The APIs used were ibuprofen, a common anti-inflammatory drug, and probucol, an anti-hyperlipidemic drug. Formulated ibuprofen and probucol with a fixed composition of the API and excipients were each prepared. Those APIs were recycled, in which up to 63 w/w% of ibuprofen and 73 w/w% of probucol were successfully recovered from drug formulations. Additionally, the procedure was also tested for commercially available medications to see if the established protocol could also be applied to any kind of drug products containing the same APIs, regardless of the excipient content and composition. Using the same method, ibuprofen and probucol were successfully extracted and recrystallized from the commercial drug products available in pharmacies, with the recovery of 86 and 73 w/w% for ibuprofen and probucol, respectively. The purity of all recovered APIs were verified by FTIR, PXRD, DSC, UV-Vis spectroscopy, and 1H NMR.
