Abstract
本发明涉及附聚体形式的药物配制剂,所述配制剂包含A)辅助剂和B)至少一种活性成分,其中所述辅助剂由如下组分组成:a)60-97重量%糖或糖醇,b)1-25重量%崩解剂,c)1-15重量%水不溶性成膜聚合物,d)0-15重量%水溶性聚合物,以及e)0-15重量%其它常规药物辅助剂,其中组分a)-e)的总和为100重量%。
Description
本发明涉及用于制备快速崩解片剂的附聚体形式的药物配制剂,所述配制剂除至少一种活性成分外还包含糖或糖醇、崩解剂和水不溶性聚合物。
在口中快速崩解和/或快速溶解的片剂对于药物的口服给药变得越来越重要。此类片剂必须在口腔中于短时间,优选30秒内崩解,具有愉悦的味道和必须不留下沙粒感。此外它们应易于制备,其中与湿法造粒相比直接压片具有显著优势,且应具有高机械强度以使它们经受得住包装程序、运输,以及从包装中挤出而不受损伤。
到目前为止描述的产品和方法均不满足这些要求或仅非常不充分地满足了这些要求。
快速崩解的片剂通常由糖和糖醇、泡腾体系、微晶纤维素和其它水不溶性填料、磷酸氢钙、纤维素衍生物、玉米淀粉或多肤组成。此外,使用水溶性聚合物、常规崩解剂(交联的PVP、交联的羧甲基纤维素的钠盐和钙盐、羧甲基淀粉的钠盐、低度取代的羟丙基纤维素L-HPC)以及基本无机的水不溶性成分(硅石、硅酸盐、无机颜料)。另外,所述片剂还可包含表面活性剂。
WO 2003/051338描述了包含甘露醇和山梨醇的可直接制片且易于压制的赋形剂配制剂。首先,通过将甘露醇和山梨醇溶解于水中和随后喷雾干燥(常规喷雾干燥和SBD法)而制备赋形剂预混合物。也可将甘露醇加入此类共加工混合物中。还包含崩解剂、助流剂、颜料和活性成分的片剂据说在口腔中于60秒内崩解。
US 2002/0071864A1描述了在口腔中于60秒内崩解并主要由喷雾干燥的甘露醇、粗粒交联聚乙烯吡咯烷酮和有限选择的活性成分的物理混合物配制的片剂。这些片剂的硬度为约40N,且产生不愉悦的沙粒口感。
根据US 6,696,085B2,将C型甲基丙烯酸共聚物用作崩解剂。C型甲基丙烯酸共聚物为抗胃液且在酸性pH范围内不溶但在如存在于口腔中的7的pH范围内可溶于水的聚合物。除低硬度(<20N)外,所述片剂还具有高的脆性(>7%)和15重量%的粗粒崩解剂高比例。因而它们具有低的机械强度,且由于粗粒崩解剂的高比例而产生不愉悦的沙粒口感。
EP 0839526A2描述了由活性成分、赤藓醇、晶体纤维素和崩解剂组成药物剂型。此外,加入甘露醇并将交联的聚乙烯吡咯烷酮用作崩解剂,以形成物理混合物。据说所述片剂在口腔中于60秒内分解。
申请JP 2004-265216描述了在口中于60秒内崩解且由活性成分、水溶性聚乙烯醇/聚乙二醇共聚物、糖/糖醇(甘露醇)和崩解剂组成的片剂。
本发明的目的是提供在口中快速崩解、留下愉悦口感、非常机械稳定并表现出高内容物均匀性的片剂。
因此,发现了一种用于制备在口中快速崩解的片剂的药物制剂,所述制剂由包含如下组分的附聚体组成:
A)由如下组分组成的赋形剂内容物:
a)60-97重量%至少一种糖或糖醇或其混合物,
b)1-25重量%崩解剂,
c)1-15重量%水不溶性聚合物,
d)0-15重量%水溶性聚合物,和
e)0-15重量%其它药物常规赋形剂,
组分a)-e)的总和为100重量%,
和
B)至少一种活性成分。
此外,发现了制备此类附聚体的方法。
此外,发现了在口中快速崩解且包含此类制剂的片剂。所述片剂在口中或在含水介质中于60秒,优选30秒,特别优选20秒内崩解。“所述片剂在pH为7.2的磷酸盐缓冲液中于37℃下表现出<60秒的崩解时间。崩解时间按照USP或Pharm.Eur在崩解测试仪中测定。”
赋形剂内容物A)具有以下具体组成:
所述药物制剂包含60-97重量%,优选70-95重量%,特别优选75-93重量%糖、糖醇或其混合物作为组分a)。合适的糖或糖醇是海藻糖、甘露醇、赤藓醇、异麦芽糖、麦芽糖醇、乳糖醇、木糖醇和山梨醇。糖或糖醇组分优选是细碎的,平均粒度为5-100μm。如果需要,可通过研磨调节粒度。优选的粒度为30-50μm。然而,合理的是也可使用小于30μm的粒度。同样合理的是可使用包含粒度不同的部分的混合物的糖或糖醇,例如30-70重量%平均粒度为<30μm的粒度部分和30-70重量%平均粒度为30-50μm的粒度部分的混合物。优选使用甘露醇、赤藓醇或其混合物。
将量为1-25重量%,优选2-15重量%,特别优选3-10重量%的崩解剂用作组分b)。崩解剂优选选自交联的聚乙烯吡咯烷酮、交联羧甲基纤维素、羧甲基淀粉钠和L-羟丙基纤维素。根据本发明交联羧甲基纤维素指交联羧甲基纤维素的钠和/或钙盐。优选的L-羟丙基纤维素具有5-16%的羟基丙氧基。
特别优选交联的聚乙烯吡咯烷酮。此类交联的聚乙烯吡咯烷酮不溶于水但不成膜。所述交联的聚乙烯吡咯烷酮的平均粒度可为2-60μm,优选小于50μm,特别优选小于30μm。非常特别优选水合能力大于6.5g/g的交联聚乙烯吡咯烷酮。在这一点上,通过以下方法测定水合能力:称量2g聚合物放入离心管中,并用40ml水使其溶胀15分钟。然后,在2000rpm下离心15分钟,并将上清液尽可能完全倒出。
水合能力=(最终重量-皮重)/初始重量
在所述配制剂中,交联聚乙烯吡咯烷酮的高水合能力导致非常迅速地崩解,并产生特别柔软的口感。
将量为1-15重量%,优选1-10重量%的水不溶性聚合物用作组分c)。这些是聚合物。优选的聚合物为在1-14的pH范围内不溶,即具有在每个pH下为pH独立的水不溶性的那些。然而,在6-14的pH范围中的任何pH下为水不溶性的聚合物也适合。
所述聚合物应为成膜聚合物。在本文上下文中,成膜指聚合物在水分散体中的最低成膜温度为-20至+150℃,优选0-100℃。
合适的聚合物是聚乙酸乙烯酯、乙基纤维素、甲基丙烯酸甲酯/丙烯酸乙酯共聚物、丙烯酸乙酯/甲基丙烯酸甲酯/甲基丙烯酸三甲基铵乙酯三聚物.甲基丙烯酸丁酯/甲基丙烯酸甲酯/甲基丙烯酸二甲基氨基乙酯三聚物.
欧洲药典以聚丙烯酸酯分散体30%、USP以Ammonio甲基丙烯酸酯共聚物和JPE以甲基丙烯酸氨基烷基酯共聚物E更详细地描述了丙烯酸酯/甲基丙烯酸酯共聚物。将聚乙酸乙烯酯用作优选的组分c)。其可以固体含量为10-45重量%的水分散体使用。另外,优选的聚乙酸乙烯酯为分子量为100000-1000000道尔顿,特别优选为200000-800000道尔顿的那种。
此外,所述配制剂可包含量为0-15重量%的水溶性聚合物作为组分d)。合适的水溶性聚合物例如为聚乙烯吡咯烷酮、乙烯基吡咯烷酮/乙酸乙烯酯共聚物、聚乙烯醇、聚乙烯醇/聚乙二醇接枝共聚物、聚乙二醇、乙二醇/丙二醇嵌段共聚物、羟丙基甲基纤维素、羟丙基纤维素、羟乙基纤维素、角叉菜聚糖、果胶、黄原胶和藻酸盐。
如果需要,由所述配制剂获得的片剂的味道和外观可通过加入量为0-15重量%的药物常规赋形剂(组分e))如酸化剂、缓冲物质、增甜剂、香料、香味增强剂和着色剂而进一步改善。在本文中如下物质特别适合:柠檬酸、酒石酸、抗坏血酸、磷酸二氢钠、环己烷氨基磺酸盐、糖精钠、天冬氨酰苯丙氨酸甲酯、薄荷醇、薄荷香料、水果香料、香草香料、谷氨酸盐、核黄素、β-胡罗卜素、水溶性着色剂和细碎的色淀。
通过加入增稠剂如高分子量多糖,口感可另外通过提高软度和体积感(sensation of volume)而改善。
另外,表面活性剂也可作为组分e)加入。适合的表面活性剂例如为月桂基硫酸钠、磺基琥珀酸二辛酯、烷氧基化脱水山梨糖醇酯如聚山梨醇酯80、蓖麻油或氢化蓖麻油的多烷氧基化衍生物如RH 40、烷氧基化脂肪酸、烷氧基化羟基脂肪酸、烷氧基化脂肪醇、脂肪酸的碱金属盐和卵磷脂。
此外,也可加入细碎的颜料以进一步改善崩解,因为它们增加了内部界面,水因此可更快速地渗入片剂中。这些颜料如铁氧化物、二氧化钛、胶状或沉淀硅石、碳酸钙或磷酸钙当然必须非常细碎,因为否则再次产生粒状味觉。
原则上可将所有活性成分用作活性成分B)。优选使用下述活性成分,特别优选以所述剂量使用。
佐米曲普坦2.5mg,利扎曲普坦5mg,盐酸苯海拉明(掩味的)20mg,溴苯那敏5mg,氯苯那敏5mg,伪麻黄碱(掩味的)30mg,对乙酰氨基酚(掩味的)250mg,布洛芬(掩味的)200mg,乙酰水杨酸250mg(掩味的),硫酸莨菪碱0.125mg,米氮平15mg,盐酸司来吉兰1.25mg,昂丹司琼4mg,奥氮平5mg,氯硝西泮1mg,盐酸西替立嗪10mg,地氯雷他定5mg,马来酸依那普利5mg,马来酸多潘立酮10mg,东莨菪碱0.25mg,奥沙西泮15mg,劳拉西泮2.5mg,氯氮平25mg,甲磺酸双氢麦角胺5mg,尼麦角林5mg,间苯三酚80mg,美托哌丙嗪7.5mg,三唑仑0.5mg,溴替唑仑(protizolam)0.5mg,曲马多50mg,洒石酸唑吡坦5mg,西沙必利5mg,利培酮2mg,阿奇霉素100mg(掩味的),罗红霉素50mg(掩味的),克拉霉素125mg(掩味的),依托红霉素250mg(掩味的),阿扑吗啡20mg,芬太尼0.6mg。
还可使用活性成分的混合物。特别合适的混合物为:对乙酰氨基酚或布洛芬或乙酰水杨酸和伪麻黄碱,对乙酰氨基酚或布洛芬或乙酰水杨酸和苯海拉明或氯苯那敏或溴苯那敏或氯雷他定。
所述剂量代表每种药物剂型的相应活性成分的绝对量.成品药物剂型中赋形剂内容物和活性成分内容物的浓度取决于药物剂型的尺寸.在片剂的情况下,通常的片剂重量为:50-1000mg,优选80-600mg.
还可向活性成分提供常规掩味涂层。用于此类涂层的合适聚合物为:氨基烷基甲基丙烯酸酯共聚物E(Eudragit E或EPO),各种配制剂中的聚乙烯醇(Opadry AMB、Kollicoat Protect),水不溶性聚合物如聚乙酸乙烯酯的组合,聚(甲基)丙烯酸酯(Eudragit NE 30D、NM 30D、RL、RS、RD、Kollicoat EMM 30D),具有水溶性或水溶胀性低或高分子量物质的乙基纤维素(聚维酮、共聚维酮、HPMC、HPC、聚乙二醇、泊洛沙姆、聚乙二醇-聚乙烯醇接枝共聚物、糖、糖醇、有机或无机盐),水溶性成膜剂(聚乙二醇-聚乙烯醇接枝共聚物、HPMC、聚乙烯醇)与脂肪、蜡、脂肪酸和脂肪醇的组合。
本发明配制剂可通过在混合机、流化床设备或喷雾塔中附聚而制备。首先将固体原料和造粒液体相互混合,然后将潮湿的混合原料干燥。根据本发明,所用造粒液体为组分c)水不溶性聚合物的水分散体。
在本发明的一个实施方案中,首先将一种或多种活性成分与糖或糖醇、崩解剂以及如果需要的组分d)和e)一起引入流化床中。
在流化床附聚中,将水不溶性聚合物(组分c))的水分散体喷雾在糖或糖醇、崩解剂、活性成分以及如果合适其它组分d)和e)的流化混合物上,从而导致细颗粒的附聚。入口气温为30-100℃,出口气温为20-70℃。
尤其随着所述附聚可加入如下赋形剂作为其它组分e):着色剂、增甜剂、香料、其它崩解剂、碳酸盐、碳酸氢盐、酸化剂或其它赋形剂。在可使用无机颜料、有机色淀或水溶性着色剂的情况下,使用着色剂例如导致均匀着色的快速崩解片剂。适合着色剂的实例为核黄素、β-胡罗卜素、花色素、胭脂红、靛蓝胭脂红、有机黄S、喹啉黄、靛蓝色淀、亮蓝、晚霞黄。这些其它物质可以固体形式放入流化床初始加料中或溶于或分散于组分c)的分散体中。如果分散体与此类物质不相容,则后者也可在与组分c)的分散体附聚之前或之后以溶液或作为悬浮液喷雾。
当在喷雾塔中制备时,优选使用所谓的FSD或SBD技术(FSD:流化喷雾干燥;SBD:喷雾床干燥)。此时,首先将糖或糖醇的水溶液喷雾干燥,并在喷雾干燥机的较低部分或在连接的流化床中加入崩解剂和喷入水不溶性聚合物的水分散体,从而使颗粒附聚。在具体变化形式中,将崩解剂分散在糖或糖醇的水溶液中,并如上所述进行所述处理。此外,可在糖或糖醇溶液的喷嘴前方再次吹细颗粒,并另外使其附聚。从晶体形式的糖或糖醇开始的程序在喷雾塔、FSD或SBD中也可以。在喷雾塔的顶部加入晶体糖或糖醇或将其加入细原料的再循环料流中。通过喷雾水不溶性聚合物的水分散体,该晶体固体在塔中附聚。
可证明对附聚法有利的是进行多步喷雾加工。开始时,保持低喷雾速率以防止初始加入的产物过湿及其因此的粘附。随着加工时间的增加,可提高喷雾速率,并因此可提高附聚的倾向。也可在加工期间以适当方式调整入口气流速率和/或温度。特别是在干燥相期间,有利的是降低入口气流速率并因此防止附聚体由于高机械应力而磨损。
可将粘合剂溶液或分散体的喷雾液滴的细度(可通过雾化气压调整)、喷嘴几何形状和喷嘴至产物床的距离认为是附聚体大小的其它调整参数。喷雾越细且越均匀,所得附聚体越细且越均匀。喷嘴离产物床越远,附聚行为越差。
此外,附聚也可在混合机中通过在混合下连续聚集而进行.此类在混合下的连续聚集形式为所谓的“Schugi造粒”.此时,使固体原料和包含水不溶性聚合物的造粒液体在连续操作的垂直设置高速混合机中相互完全混合(还参见M.Bohnet,“Mechanische Verfahrenstechnik”,Wiley VCHVerlag,Weinheim 2004,第198页及随后各页)。
根据具体实施方案,将崩解剂悬浮在水不溶性聚合物的水分散体中。
由此获得的附聚体的平均粒度为100-600μm,优选120-500μm,特别优选140-400μm。水不溶性成膜聚合物用作用于使细糖或糖醇晶体、活性成分颗粒、崩解剂和如果合适其它赋形剂附聚成较大颗粒的凝结剂。
在本发明其它实施方案中,也可首先使赋形剂内容物A)附聚,然后使A)在其它造粒步骤中与一种或多种活性成分一起附聚。
在该实施方案的变化形式中,首先将附聚的赋形剂内容物和活性成分引入流化床中,并通过粘合剂溶液造粒。此时粘合剂溶液包含选自组分d)的水溶性聚合物作为粘合剂。其优选为水溶液。粘合剂浓度可为5-40重量%。
优选的粘合剂为Fikentscher K值为12-120,特别是K30的水溶性聚乙烯吡咯烷酮,由30-70重量%,优选40-60重量%N-乙烯基吡咯烷酮和30-70重量%,优选40-60重量%乙酸乙烯酯组成的乙烯基吡咯烷酮-乙酸乙烯酯共聚物,聚乙烯醇、聚乙二醇与聚乙烯醇的接枝共聚物、羟丙基甲基纤维素、羟丙基纤维素、羟乙基纤维素和明胶。
在第二个变化形式中,首先将附聚的赋形剂内容物引入流化床中,并将活性成分内容物加入上述粘合剂溶液中。
在其中水溶性粘合剂(组分d))必须已优选以0.5-10重量%的量存在于预附聚的赋形剂内容物中的其它变化形式中,所用造粒液体为无聚合物粘合剂的水。此时可将组分e)组的其它赋形剂加入水中用于造粒。合理的是还可将一种所述糖或糖醇加入水中。
另外,用于其中首先使赋形剂内容物附聚的所有这些实施方案的变化形式中的设备和工艺参数与上文就使赋形剂内容物和活性成分内容物同时附聚所述相同。
有利的是本发明配制剂也可用于制备使用前在一杯水中崩解的片剂。当然制备完整吞服的片剂也可以。
对片剂的制备而言,可使用常规方法,其中直接制片和辊压特别有利。由于本发明配制剂的特殊性能,通常仅需要活性成分、本发明配制剂和润滑剂。因此,所述片剂配制剂非常简单,非常易可再生产,且所述方法易于确立。
令人惊讶地发现水不溶性成膜聚合物明显加速了片剂的崩解。这更加令人惊讶,因为此类聚合物通常用于制备在几小时内不崩解的缓释药物剂型。使用聚乙酸乙烯酯作为水不溶性聚合物时的崩解时间比水溶性聚合物的情况明显更短。
此外,本发明配制剂具有极好的可流动性和可压制性,这导致机械上非常稳定的片剂。借助本发明药物配制剂制备的片剂的硬度>40N。硬度通常为60N以上,即便是使用难以压制的活性成分。脆性<0.2%。因此在常规片剂加工期间不存在损坏。
由于细小的交联聚乙烯吡咯烷酮,当在潮湿条件下储存时,所述片剂在片剂表面实际上没有表现出变化。与粗交联聚乙烯吡咯烷酮相反,没有由于显著溶胀的颗粒而形成突起。因此,本发明配制剂在储存期间非常稳定且保持其吸引人的外观。
活性成分颗粒通过造粒与赋形剂颗粒牢固结合,并不再可能分聚.由此显著提高了片剂,尤其是低活性成分含量片剂的内容物均匀性.显著提高了片剂性能的再现性.由此可处理物理化学性能与赋形剂相比差别很大的活性成分.令人惊讶的是,与活性成分一起造粒没有导致溶解速率变慢,尽管这由于颗粒较强的粘附而在预料之中.
所述药物制剂还可用于其它药物剂型:其它药物剂型的实例为具有计量装置的囊或颗粒容器。
实施例
通过两步附聚法进行制备,其中首先选择较低的喷雾速率,随后提高喷雾速率。在两步附聚法中使用以下制备条件:

粘合剂水溶液/水分散体的浓度: 20重量%
入口气温: 50℃
出口气温: 30℃
初始喷雾速率(10min): 15g/min
调整后的喷雾速率: 20g/min
所用崩解剂为:来自BASF的Kollidon CL-SF:交联聚维酮,平均粒度为17μm的交联聚乙烯吡咯烷酮。所用聚乙酸乙烯酯为:来自BASF的Kollicoat SR 30D:用2.7重量%聚乙烯吡咯烷酮和0.3重量%十二烷基硫酸钠稳定的市售聚乙酸乙烯酯水分散体。来自BASF的IR:由75重量%聚乙烯醇和25重量%聚乙二醇组成的平均Mw.为45000D的市售接枝聚合物。来自BASF的VA 64:共聚维酮,由60重量%NVP和40重量%VAc组成的共聚物。
表1:以重量%计的附聚体A-E的组成
将由此制备的附聚体与2.0重量%润滑剂(硬脂酸镁)在Turbula混合机中混合10min。然后在装备齐全的偏心压机(Korsch XP 1)中将这些混合物压制成重量为300mg、直径为10mm和硬度为40-55N的双平面片剂。
调查片剂的硬度(来自Kraemer的HT-TMB-Cl-12F片剂测试仪)、在pH为7.2的磷酸盐缓冲液中的崩解时间(ZT 74崩解测试仪,Erweka)和在pH为1.2的模拟胃液中的释放速率(释放设备,Erweka)。
表2:配制剂A-E的片剂性能
预附聚赋形剂内容物与活性成分的造粒
通过使甘露醇(90重量%)和交联的PVP(5重量%)聚乙酸乙烯酯(5重量%)一起流化床附聚而制备快速崩解的赋形剂。对由此制备的产物进行进一步的造粒步骤:其中在第一实验中在每种情况下均首先引入预附聚的赋形剂和活性成分,并利用粘合剂溶液将其粒化,在第二变化形式中首先仅引入预附聚的赋形剂,将活性成分加入粘合剂溶液中。所用造粒方法是流化床法和混合机造粒。原则上可使用所有造粒方法。也可使粘合剂干燥混合,然后可喷水或加入水。
在一个具体实施方案中,仅通过加入水将快速崩解的赋形剂与活性成分一起造粒。此时可通过将糖或糖醇加入水中提高造粒效果。
以类似于就变化形式1所述的方式,也可在所述造粒中使用着色剂、增甜剂、香料、其它崩解剂、碳酸盐、碳酸氢盐、酸化剂或其它赋形剂。
表3:工艺参数
表4:以重量%计的附聚体F-J的组成
造粒后使混合机造粒所得颗粒通过1mm的筛网进行筛分,在托盘上于室温下干燥过夜,然后使其通过0.8mm的筛网。
使由此制备的附聚体与2.0重量%润滑剂(硬脂酸镁)混合,并在实施例F和J中还与另外的3%Kollidon CL-SF混合,然后在旋转式压片机(Korsch XL 100)中将其压制成硬度为40-55N的片剂。
调查片剂的硬度(来自Kraemer的HT-TMB-Cl-12F片剂测试仪)、在pH为7.2的磷酸盐缓冲液中的崩解时间(ZT 74崩解测试仪,Erweka)和在pH为1.2的模拟胃液中的释放速率(释放设备,Erweka)。
表5:配制剂F-J的片剂性能
硬度[N] | 脆性[%] | 崩解时间[s] | 释放速率[%,10min后] | |
F | 43 | <0.2 | 89 | 60 |
G | 48 | <0.2 | 62 | 95 |
H | 42 | <0.2 | 51 | 100 |
J | 45 | <0.2 | 59 | 70 |
