01 溶解度測(cè)試


溶解度測(cè)試是一種用于評(píng)估在嚴(yán)格控制的條件下化合物溶解形成溶液的速率和量的測(cè)試方法。在美國(guó)藥典(USP)藥物產(chǎn)品專論中,這種測(cè)試有助于評(píng)估藥物產(chǎn)品的性能,并指示何時(shí)產(chǎn)品性能低于標(biāo)準(zhǔn)。然而,通過(guò)測(cè)試并不能明確證明樣品的生物可用性或其他產(chǎn)品的生物等效性;未通過(guò)測(cè)試是一個(gè)值得關(guān)注的原因。通常,對(duì)于口服藥物產(chǎn)品,美國(guó)藥典專論要求使用第 711 章《溶解度》中描述的儀器進(jìn)行溶解度測(cè)試1。


美國(guó)藥典儀器 1(baskets)和 2(paddles)被廣泛用于對(duì)口服固體藥物產(chǎn)品進(jìn)行溶解度測(cè)試。第 711 章中的“儀器適用性"部分描述了溶解度儀器的資格認(rèn)證程序和要求2。分析儀器的資格認(rèn)證/校準(zhǔn)也是食品和藥物管理局(FDA)現(xiàn)行良好生產(chǎn)規(guī)范(cGMPs)以及國(guó)際標(biāo)準(zhǔn) ISO/IEC 17025 所要求的,后者規(guī)定了測(cè)試和校準(zhǔn)實(shí)驗(yàn)室能力的通用要求3,4

02 目的


本研究的目的是評(píng)估在使用脫氣和非脫氣溶出介質(zhì)(即純凈水)時(shí),潑尼松溶解量之間的百分比差異,采用的儀器為 II 型儀器(paddles)和美國(guó)藥典 I 型儀器(baskets)美國(guó)藥典 40 目。


測(cè)試程序和結(jié)果如下:

在進(jìn)行溶解度測(cè)試之前,根據(jù)電磁兼容性(EMC)和美國(guó)藥典(USP)溶解性能驗(yàn)證測(cè)試(PVT)標(biāo)準(zhǔn)-潑尼松片劑的要求,對(duì)儀器進(jìn)行了資格認(rèn)證。按照美國(guó)藥典的指示,使用當(dāng)前的片劑溶解性能驗(yàn)證標(biāo)準(zhǔn),批號(hào) F161Y0,有效期至 2024 年 11 月 14 日,進(jìn)行溶解度測(cè)試。每片含有 10 毫克潑尼松。


在本研究中,按照美國(guó)藥典總章<711>溶解度中描述的程序,對(duì)溶解介質(zhì)進(jìn)行脫氣處理:“在輕輕攪拌的同時(shí)加熱介質(zhì)至約 41°C,立即在真空下使用孔隙率小于或等于 0.45μm 的過(guò)濾器過(guò)濾,并保持充分?jǐn)嚢瑁^續(xù)在真空下攪拌約 5 分鐘。" 使用相同的設(shè)置重復(fù)此步驟,但使用未脫氣的溶解介質(zhì)。在測(cè)試期間,使用了兩種類型的 Apparatus II(paddles)攪拌設(shè)備:不銹鋼或聚四氟乙烯(PTFE)。此外,還使用了 40 目不銹鋼 Apparatus I paddles 來(lái)測(cè)試使用脫氣或未脫氣溶解介質(zhì)的溶解情況。


使用當(dāng)前批號(hào)為 R083A0 的潑尼松參考標(biāo)準(zhǔn)制備了標(biāo)準(zhǔn)溶液。使用 10 毫米石英池在島津分光光度計(jì) UV 1800 型號(hào)上,于 242nm 波長(zhǎng)處同時(shí)測(cè)量樣品和標(biāo)準(zhǔn)的紫外吸收。根據(jù)內(nèi)部程序記錄原始數(shù)據(jù)。使用美國(guó)藥典提供的工具計(jì)算結(jié)果,并在表 1 中報(bào)告。

表格2. 使用 Apparatus I 的片劑溶解性能驗(yàn)證標(biāo)準(zhǔn)結(jié)果

03 結(jié)論


根據(jù)上述結(jié)果,所有測(cè)試均符合接受標(biāo)準(zhǔn),但當(dāng)使用不銹鋼 Paddles 在非脫氣介質(zhì)中進(jìn)行時(shí),CV 百分比未達(dá)標(biāo),僅略低于 0.1%,若在相同條件下重復(fù)測(cè)試,這一差異可能會(huì)朝任一方向發(fā)展。此外,在非脫氣介質(zhì)中的潑尼松溶解百分比也略高于脫氣介質(zhì)的結(jié)果。非脫氣介質(zhì)中的 CV 百分比似乎也更高。由于預(yù)期在采用 Apparatus 1(baskets)的測(cè)試中會(huì)有更高的釋放率,因此與 Apparatus 2(paddles)的測(cè)試結(jié)果相比,這種變異似乎較小。


該研究旨在評(píng)估脫氣過(guò)程對(duì)結(jié)果的影響,因此未進(jìn)行額外的測(cè)試。根據(jù)上文所示的研究數(shù)據(jù),顯而易見,無(wú)論使用PTFE還是Paddle,溶解藥物產(chǎn)品的釋放量只有微小的差異。如果使用溶出性能驗(yàn)證標(biāo)準(zhǔn)片劑來(lái)驗(yàn)證溶出測(cè)試儀的性能,建議按照美國(guó)藥典的建議進(jìn)行脫氣處理。
