Description

制备形态均匀之微胶囊的方法
技术领域
本发明涉及制备形态均匀之微胶囊的方法,该胶囊包含肽、蛋白质或者其他水溶性生物活性物质作为主要成分,以及由此方法制得的微胶囊。
背景技术
众所周知,肽和蛋白质是具有相当大药效学的活性成分,但是由于对胃中的酸性环境的水解敏感性以及酶降解的原因,他们在口服给药时会分解,并因此使其一部分失活,使得他们在胃肠道中的作用被大大降低。
然而,即使在非胃肠道给药后以及特别是在静脉给药后,由于半衰期经常非常短,蛋白质和肽的快速失活也可被观察到。这意味着尽管相当大的药效学和理论上非常低的治疗剂量,多次给药高剂量仍是必须的,这对患者意味着非常大的负担。
可避免上述缺陷的合适剂型是聚合物微胶囊或者聚合物纳胶囊(nanocapsules)形式的储药系统,该系统对肽已广为人知,并在文献中有所描述。
他们具有以下优点:
—防止肽和蛋白质快速失活,
—较低的剂量也可是药理学有效的,
—减少多次给药,
—原则上肽和蛋白质的控制释放是可行的,
—胶囊包封的活性成分可以直接的方式转运,以及
—降低不期望的副作用。
水溶性物质的微胶囊或纳胶囊化的已知方法分为如下:
—凝聚或者乳化相分离
—通过喷雾干燥包胶
—在有机或含水相中进行溶剂蒸发。
所有的方法都包括将活性成分嵌入在可生物降解之聚合物基体或共聚物基体中的步骤。
文献中已知的为此目的的聚合物有聚酰胺、聚酸酐、聚酯、聚原酸酯、聚乙酸酯、聚内酯、聚原碳酸酯等。目前,主要使用的是聚丙交酯—共—聚乙交酯聚合物。
这样,从US4,675,189(Syntex Inc.)、US4,835,139(Debiopharm S.A.)和EP 302 582 B1(Southern Research Inst.)中可知晓胶囊形式的水溶性肽和蛋白质的药物组合物,它可以根据凝聚或乳化相分离来制备。
根据所公开的内容,其描述的方法中使用的共聚物优选为聚—(丙交酯—共—乙交酯)聚合物,将所述聚合物溶解在卤化有机溶剂中,优选为二氯甲烷,然后将肽水溶液分散在上述溶液中。接着加入所谓的凝聚剂。所述凝聚剂在有机溶剂中是可溶的,但是聚合物不溶解在凝聚剂中,使聚合物沉淀,并包容分散的多肽。对于凝聚剂,通常使用硅油用于相分离。在加入硅油后,还必须另外再加入大量的庚烷,该试剂的作用是确保微胶囊的沉降。
该方法的包胶率大约为70%(US4,835,136)。如此制得的微胶囊的直径为1-500μm,根据实施例优选为10-50μm。
除使用毒理学上有问题的试剂如二氯甲烷、庚烷以及硅油外,该方法的缺陷还包括使用大量的在使用凝聚剂如硅油进行包胶时需要的溶剂。
在EP-A315875(Hoechst AG)中描述的方法是用于制备水溶性肽和蛋白质的可生物降解的微胶囊,该方法基于喷雾干燥法,其中,肽或蛋白质的水溶液在有机聚合物溶液中进行乳化,然后喷雾干燥该乳化液。
对于可生物降解的聚合物,使用聚羟基丁酸和聚(丙交酯—共—乙交酯)聚合物的混合物,他们的混合比在99∶1-20∶80之间。
肽或蛋白质是以微小形式或者水溶液存在。对于溶剂,可考虑氯仿、二氯甲烷、DMF或者由水/乙醇/氯仿组成的溶剂混合物。根据实施例,使用氯仿。优选在45-95℃之间的温度进行喷雾干燥。
该方法的缺陷是在使用非卤化溶剂而且干燥过程的温度同时较高时,有产生爆炸的危险。而且,非可燃性溶剂如二氯甲烷的使用则导致在终产物中残留毒理学有害的溶剂污染物。另外,经喷雾干燥的微胶囊基本上表现出非常强的附聚趋势,附聚物的粒径约为100μm。
在两件加拿大专利申请CA2,100,925(Rhone-Merieux)和CA2,099,941(Tanabe Seiyaku Co.)中描述了根据“溶剂蒸发法”制备的微粒。
通常情况下,该方法是将肽或蛋白质的水溶液分散在有机聚合物溶液中,或者是活性成分晶体悬浮在聚合物溶液中。在用表面活性剂加入第二含水相后,蒸发聚合物溶剂。
该方法是高度可变的,而且通常产生W/O-或者复合W/O/W乳液。
根据CA2,099,941,水溶性活性成分和可生物降解的聚合物首先溶解在上述两种成分都可溶解在其中的溶剂或者溶剂混合物中。然后除去该溶剂,并将如此产生的固体分散体溶解在不与水混溶的有机溶剂中。所产生的溶液(油相)在含水相中乳化,由此产生W/O乳液。
最后,蒸发该乳液中的油相中的有机溶剂。
该专利的具体实施例涉及聚(丙交酯—共—乙交酯)聚合物(PLGA)作为基体以及释放促甲状腺激素或其衍生物的激素(TRH)作为活性成分,他们首先溶解在由乙腈/乙醇以及任选水,或者只有乙腈,或者由乙腈和含水明胶,或者二氯甲烷和乙醇组成的混合物中。
作为固体分散体之溶液中的有机溶剂,可使用二氯甲烷或者氯仿。含水聚乙烯醇溶液代表含水相。
微胶囊的直径约为1-100μm,根据具体实施例约为50μm-<100μm。
根据CA2,100,925,LHRH激素和类似物的微胶囊是通过将粉末形式的LHRH激素先分散在两个有机溶剂中来制备的,其中,一个溶剂(上述分散剂)可通过简单的搅拌产生粉末化的激素的均匀分散液。第二溶剂易与水混溶,并因而使有机相微分散在含水相中成为可能。
作为第二溶剂,可使用二氯甲烷或者氯仿。胶囊的直径在1-250μm之间。优选的是,胶囊大于50-60μm。
如此产生的微胶囊的形态差异非常大。如上所述,使用的卤化溶剂在毒理学上是有害的。另外,该方法还需要相当大量的表面活性剂。
发明内容
本发明的目的是提供通过使用毒理学上无害的溶剂来简单且温和地制备形态均匀、非附聚之微胶囊的方法,其包胶率至少为85%,优选大于90%,而且产生的粒径范围在200nm-500μm的微胶囊具有非常高的包胶浓度(Deladungsgrad)。另外,此方法使“按比例放大(scaling-up)”成为可能。
在本发明中,提供一种制备形态均匀之微胶囊的方法,其包括以下步骤:
将选自于以下组中的聚合物物溶解在部分与水混溶的无卤素的溶剂或部分与水混溶的无卤素的溶剂混合物中形成聚合物溶液:聚酰胺、聚酸酐、和聚酯;
在上述聚合物溶液中添加水溶性活性成分的溶液以形成聚合物/活性成分分散液;在该聚合物/活性成分分散液中添加包含表面活性剂的水溶液达到最终的总体积,其中聚合物/活性成分分散液占总体积的量为41-49体积%、优选为43-46体积%,而表面活性剂溶液占总体积的量为51-59体积%、优选为54-57体积%;然后
除去溶剂,产生药物浓度为3-30重量%的微胶囊。

具体实施方式
令人惊奇的是,简单地使用“诱导相转移(Induced Phase Transition)”法即可实现本发明的目的,该方法是如下进行的:将通常用于制备微胶囊的聚合物,如由羟基羧酸组成的聚酯或者由羟基羧酸聚酯和聚乙二醇(PEG)组成的嵌段共聚物,溶解在不与水混溶或者部分与水混溶的无卤素的溶剂或溶剂混合物中,然后将经缓冲的活性成分的溶液分散在上述溶液中,所述经缓冲之溶液的pH在6.0-8.0之间。均化产生稳定的W/O乳液,在该乳液中加入作为外层相的包含表面活性剂或者表面活性剂混合物的含水溶液,并同时搅拌,由此得到三相W/O/W乳液。然后使用常规方法除去溶剂或者溶剂混合物,优选在真空和/或空气/氮气流中。浓缩微胶囊,并选择性地进行冻干。
在此情况下,通过搅拌速度控制粒径,其中,在较高的搅拌速度下得到较小的粒径(≤8μm)——此粒径对于静脉给药的产品是必须的。
任选地,在除去溶剂后,微胶囊另外进行“交叉流(cross-flow)”过滤,由此除去残留的表面活性剂和残留的溶剂部分。其结果是,可减少或避免“早爆(initial burst)”,即在给药后活性成分立即大量释放(因为活性成分黏附在颗粒表面上)。
对于冻干,可选择性地加入细胞保护剂如糖、糖醇、或者聚乙烯吡咯烷酮衍生物。
可在根据本发明的方法中使用的羟基羧酸聚酯优选为:
聚乙交酯(PGA)和乙交酯的共聚物,如乙交酯/丙交酯共聚物(PGA/PLLA)或乙交酯/亚丙基碳酸酯共聚物(PGA/TMC);L-聚丙交酯(PLA)和聚丙交酯的立体共聚物,如聚L-丙交酯(PLLA)、聚DL-丙交酯共聚物和L-丙交酯/DL-丙交酯共聚物;PLA的共聚物如丙交酯/四甲基丙交酯共聚物、丙交酯/δ-戊内酯共聚物和丙交酯/ε-己内酯共聚物;聚β-羟基丁酸(PHBA)、PHBA/β-羟基戊酸共聚物(PHBA/HVA)、聚β-羟基丙酸(PHPA)、聚p-二恶酮(PDS)、聚δ-戊内酯、疏水化多糖、疏水化透明质酸、疏水化葡萄糖或疏水化支链淀粉和聚ε-己内酯。
对于羟基羧酸聚酯和线性或星状聚乙二醇(PEG)的嵌段共聚物,可在本发明方法中使用以下物质:
由PLA和PEG构成的AB-嵌段共聚物、由PLA-PEG-PLA构成的三嵌段共聚物、S(3)-PEG-PLA嵌段共聚物和S(4)-PEG-PLA嵌段共聚物。
根据本发明优选使用聚合物Resomer505,特别是ResomerRG-756或者ResomerRG-858。
Resomer是Bhringer Ingelheim Company的商标。在此它是(DL-丙交酯—共—乙交酯)—聚合物。
本发明优选的无卤素的溶剂或溶剂混合物是丙酮,乙醇,乙酸烷基酯如乙酸甲酯、乙酸乙酯、乙酸丙酯、乙酸异丙酯或乙酸丁酯,烷基甲酸酯如甲酸甲酯、甲酸乙酯、甲酸丙酯、甲酸异丙酯或甲酸丁酯,甘油三乙酸酯,柠檬酸三乙酯和/或C1-C4烷基乳酸酯,如乳酸甲酯或乳酸乙酯。
特别优选使用的是乙酸乙酯、乙酸异丙酯和甲酸丙酯。
为本发明的目的,经缓冲的溶液是肽、蛋白质或他们生理上相容盐的水溶液或者其他水溶性生物活性物质的水溶液,其优选用三(羟甲基)氨基甲烷溶液或者磷酸盐缓冲液来调节至pH在6.0-8.0之间,优选为6.5-7.4之间。
其他根据本发明可使用的缓冲液是柠檬酸盐缓冲液,其中,该缓冲液的浓度通常在5-300mmol/l之间。
任何水溶性肽或蛋白质可用根据本发明的方法来包胶。根据本发明的方法特别适合于包胶人血清白蛋白、胰岛素、干扰素和LHRH拮抗剂或其类似物。
以下提到的人血清白蛋白、胰岛素、干扰素和肽之形态均匀的微胶囊可用根据本发明的方法非常有利地制得:
a)DesA(2)Nal-beta-Ala-DCpa-DPal-Ser-Tyr-DCit-Leu-Arg-Pro-DAla-NH2
b)DesA(2)Nal-Gly-DCpa-DPal-Ser-Tyr-DCit-Leu-Arg-Pro-DAla-NH2
c)Ac-DNal-DCpa-DPal-Ser-Tyr-DLys(Mor)-Leu-Lys(Mor)Pro-DAlaNH2
DesA(2)Nal和D-Cit的意思以及肽a)-c)的结构见图1或2。
为本发明的目的,优选的表面活性剂是以下物质:Poloxamere组、聚乙二醇烷基醚、多乙氧醚(Tween、Span)、蔗糖酯(Sisterna,荷兰)、蔗糖酯(Ryoto sugar esters,东京)、明胶、聚乙烯吡咯烷酮、脂肪醇多甙、Charps、Charpso、癸基-β-D-吡喃葡糖苷、癸基-β-D-吡喃麦芽糖苷、十二烷基-β-D-吡喃麦芽糖苷、油酸钠、Poloxamine组、聚乙二醇、聚乙烯醇、聚氧乙基化脂肪酸醚(Brij)、Triton X100或他们的混合物。
优选使用聚乙烯醇、Brij、Poloxamere、Poloxamine和Tween
本发明的主题还包括根据本发明的上述方法制备的形态均匀的微胶囊,其直径为200nm-500μm,优选为0.2-8μm。
因为聚合物和溶剂的有利形成作用,在根据本发明的方法中不发生微胶囊的附聚形成。
因此,图3和4表示根据实施例10(图3)和实施例15(图4)制造的根据本发明的微胶囊的光显微照片。图象中的1毫米相当于实际中的1μm。该照片清楚地显示出均匀的形态,无颗粒附聚物存在。
本发明方法的包胶率至少为85%,所达到的包胶率优选为90-95%之间。包胶率定义为被包封的活性成分的质量×100/活性成分的质量。由此产生的微胶囊的包胶浓度为3-30%(包胶浓度=活性成分的质量×100/(活性成分的质量+聚合物的质量))。
以下将在实施例中详细地描述本发明,但本发明并不囿于此。
