Description

调节释放剂型
发明背景
1.发明领域
本发明涉及调节释放剂型,例如调节释放药物组合物。更具体说,本发明涉及的调节释放剂型具有一个核仁和围绕该核仁的衣壳。所述核仁含有至少一种活性成分,围绕的衣壳在该剂型接触液体介质,如水或胃肠液后,提供了所述活性成分1小时以上的延迟溶解,这种延迟不依赖于液体介质的pH。
背景信息
长期以来采用调节释放药物剂型,可具体通过减少病人每日必须服用的药量来优化药物的输递和提高病人的顺从性。为此目的,常需要减慢剂型中药物(一类特别优选的活性成分)释放入病人胃肠(g.i.)液的速度,即减缓药物释放以提供该药物在机体中的长时间作用。
口服药用活性成分抵达机体中其作用部位的速度取决于许多因素,包括药物通过胃肠(g.i.)粘膜吸收的速度和程度。要被吸收入循环(血液)系统、药物必须先溶于胃肠液。许多药物扩散通过胃肠粘膜比溶解要快,此时,活性成分的溶解就成为药物吸收的速率限制步骤,通过控制溶解速度就可以控制药物吸收入病人循环系统的速度。
调节释放剂型的重要目标是提供药物的理想的血浓度与时间的曲线图(药代动力学图或PK)。药物的PK图基本上受药物吸收入血液的速度和药物从血液消除的速度的支配。理想类型的PK图在许多因素中取决于具体药物的活性成分和待治疗的生理状况。
可通过输递调节释放性溶解方式的剂型实现许多药物和生理状况的理想PK曲线图,此时,剂型在病人消化后其中的药物释放可按预定时间延迟。迟后期(“迟后时间”)之后可快速释放活性成分(“延迟后的暴发性释放”)或持续(延长、延时或延迟)释放活性成分(“延迟后的持续释放”)。
特别理想类型的调节释放PK曲线图是“脉动式”曲线图。例如此图中第一剂量药物是立即输递,然后延迟一段时间,此段时间内,血液中该药物的治疗浓度维持在接近第一剂量的水平,然后或快速释放或持续释放该药物剩余的剂量。
设计调节释放系统特别困难方面包括体内延迟时间的可预测性和重复性。生理学系统如人的胃肠道有着很高程度的内在和内部变化,例如小肠运动和pH值的变化。对于重复性和可预测性,需要一种不依赖于调节释放药物剂型所处环境pH的调节释放机制。
剂型以减慢的速度(如延迟性、脉动性、持续性、延长、延时或延迟释放)输递药物从所周知的机制包括扩散、腐蚀和渗透。
一种通过扩散控制的释放系统,将活性成分包含分布在整个不溶性多孔基质中,活性成分必须扩散通过这种基质才能被病人血流所吸收。在下沉(sink)状况(即基质表面的药物浓度大大高于大量溶液中的药物浓度)下给定时间中药物释放的量取决于基质的面积(A)、扩散系数(D)、基质的孔隙率(E)和曲率(T)、药物在溶液介质中的溶解度(Cs)、时间(t)和剂型中的药物浓度(Cp):
M=A(DE/T(2Cp-ECs)(Cs)t)1/2
注意上述关系式中,药物释放的量通常与时间的平方根成比例。假设剂型中基质的孔隙率和曲率等因素是恒定的,药物释放量与时间平方根的图谱应为线性曲线。
常用的通过腐蚀控制的释放系统,包含一种药物分布在其中的“基质”。该基质通常含有表面可膨胀的材料,此材料能一层一层地慢慢溶解掉,随其溶解药物即释放出来。这些系统的药物释放速度,dM/dt,取决于该基质的剥蚀速度(dx/dt),基质中药物的浓度状况和该系统的表面积(A):
dM/dt=A{dx/dt}{f(C)}
此外,上述一项或多项的变化,如表面积的变化,通常导致不恒定的药物释放速度。通常,腐蚀控制释放系统的药物释放速度遵循一级动力学规律。
另一种腐蚀控制输递系统,采用可膨胀性能通过表面剥蚀慢慢溶解掉的材料,也可用于提供药用活性成分的调节释放。例如,调节释放可采用脉动式或重复式作用的输递系统,该系统输送一次立即释放的剂量,然后经过预定的延迟时间后,输递后续剂量。这些系统中,延迟时间(T1)取决于腐蚀层的厚度(h)和基质的腐蚀速度(dx/dt),后者又取决于基质组分的膨胀速度和溶解度:
T1=h(dx/dt)
这些系统在给定时间内的药物释放累积量通常遵循以下公式:
M=(dM/dt)(t-T1)
其中:dM/dt见以上扩散控制的或腐蚀控制的公式所述,T1是延迟时间。
设计剂型常常是采用上述机制的组合以达到某具体活性成分的特别理想的释放曲线图。
目前的调节释放系统受到了用于制造它们的方法以及适合用于当前方法材料的限制。可提供调节释放性能的衣壳或包衣通常采用常规方法,如在包衣盘中喷雾包衣来施加。盘法包衣产生基本上围绕核仁的一层衣壳。此层衣壳的功能受到其本身限制。可以通过盘法包衣施加多层同心园衣壳,各层具有不同功能,然而这类系统受到了外层衣壳必须先溶解,然后,后续的各层才能发挥功能的限制。此外,通过喷雾法施加的包衣组合物受到其粘性限制。喷雾包衣法另一有限性是耗时和成本高。一种提供药物调节释放众所周知和常用的设计,是采用肠包衣材料,给含药物的颗粒或剂型的表面包衣。肠包衣材料通常选自仅在某种pH范围高于典型胃液,例如pH高于5.5、高于6.0、高于pH7.0的液体环境中才溶解的聚合物系统。虽然这些系统可用于保护某些酸不稳定性活性成分免受胃液破坏,或保护胃粘膜不受某些活性成分的损害,但由于胃肠道pH和运动的变化,这些系统用于程控定时调节释放系统受到限制。
常规喷雾包衣法实现了pH不依赖性的药物调节释放。例如G.Maffione等在“高粘性HPMC作为膜包衣剂”,Drug.Development and Industrial Pharmacy(1993),19(16),2043-2053中,叙述了一种核仁或片型基质,包围有一衣壳或包衣,提供了延迟的暴发性溶解曲线模式。包衣占该核仁重量的12.5-25%。优选的包衣配方采用分散在非水性溶剂中的可膨胀膜,其喷雾能力需要低浓度聚合物(5-10%)和用乙醇作为“非水性溶剂”。
也已知道盘法包衣输递的第一剂量活性成分来自包衣,第二剂量活性成分来自核仁。例如,美国专利4,576.604公开了一种渗透装置(剂型),其含有一层壁(包衣)围绕的药物小室,包衣中含有立即释放剂量的药物,内部药物小室装有持续释放剂量的药物。
或者,常规的控释系统可通过压缩制备,产生或者堆叠的多层构型,或者核仁和衣壳构型,通过压缩制备调节释放剂型的例子见美国专利5,738,874和6,294,200以及WO 99/51209。
有可能通过压缩包衣产生pH不依赖性定时药物调节释放。美国专利5,464,633公开了通过压缩包衣工艺施加外包衣层的调节释放剂型。包衣重量为核仁重量的105-140%,以产生具有所需时间调节释放方式的产品。
压缩包衣剂型受到衣壳厚度和衣壳组成的限制。例如,Gunsel等在《药物剂型表》(Pharmaceutical Dosage Forms-Tablets)的“压缩包衣和层状片剂”(Compression-coated and layer tablets)”,H.A.Lieberman,L.Lachman和J.B.Schwarty编(第二版,重编和增订,Marcel Dekker有限公司,247-284页,中揭示的压缩衣壳厚度通常在800-1200微米之间。
本发明的一个目的是提供一种剂型,该剂型含有一个核仁和围绕该核仁的衣壳,此核仁含有至少一种活性成分,围绕核仁的衣壳重量至少是该核仁重量的50%,衣壳在该剂型接触液体介质时提供所述活性成分1小时以上的延迟溶解,这种延迟不依赖于液体介质的pH。

所述活性成分在该剂型中以治疗有效量存在,该有效量口服后能产生所需的治疗反应,本领域技术人员不难确定。确定待给予药物的具体活性成分的有效量时,必须考虑该活性成分的生物利用度特性、剂量方案、患者年龄与体重和其它因素,这是该领域知道的。通常,所述剂型含有至少5%重量,优选含有至少50%重量的活性成分。一优选实施例中,所述核仁含有至少25%重量的活性成分(根据核仁重量计算)。

一优选实施例中,本发明的衣壳不论用无溶剂制模工艺或基于溶剂的制模工艺制备,都基本上设有直径0.5-5.0微米的孔,本文所用“基本上没有”指衣壳中直径0.5-5.0微米的孔体积不到约0.02cc/g、优选不到约0.01cc/g,便优选不到约0.005cc/g。相反,通常压缩材料所具有的该直径范围的孔体积高于0.02cc/g。
用于本发明衣壳的孔体积、孔直径和密度可采用Qantachrome InstramentsPoremaster60水银流入孔测量仪和相关的计算机软件程序的“Porowin”进行测定。此方法见Quomtachrome Instruments PoreMaster Operation Manual。PoreMaster通过加压灌入非湿性液体(水银)来测定固体或粉末中的孔体积和孔直径,加压可排空单个小室(透度计)中的样品,给该小室填充水银围绕此样品,并通过以下方法向样品小室(油)压力发生器(最高达60000psi)。通过加压下,水银从样品外部进入样品孔后水银容量的变化来测定流入体积。直接从以下所谓“Washbumd等式”:d=(4γ(cosθ))/P来计算发生水银流入孔的相应孔径(d),其中γ是液体水银的表面张力,θ是水银和样品之间的接触角,P是施加的压力。
孔容量测定用的仪器
(1)PoreMaster60 Quantachrome仪。
(2)分析天平,秤重精度0.0001g
(3)干燥器。
测定所用试剂

(5)清洗样品小室用的异丙醇或甲醇,
(6)清洗小室用的液体去污剂。
过程
样品保存在密封包装中或干燥器中直到分析时。打开真空泵,用液氮充满水银冷蒸气汽水阀,压缩气体调节至55psi提供。打开此仪器预热至少30分钟。按操作说明书安装空的透度计小室并记录重量。将小室安置于低压状态,选择分析手册中的“排空和单充填(evacuation and fill only)”选项,并采用以下设置:

本发明的衣壳不论用无溶剂模制工艺还是基于溶剂的模制工艺制备,通常都具有表面光泽。当用本文实施例6方法测定时,至少有约150光泽度单位,如至有少约175光泽度单位,或至少有约190光泽度单位。相反,通常的喷雾包衣光泽值不到约150光泽度单位。
消费者喜爱表面高光泽的剂型,因为它们美观雅致看上去易吞食。衣壳的表面光泽取决于许多因素,包括衣壳的组成、形成衣壳的方法,和如果采用模具,该模具的表面情况。
可采用TriCor Systems有限公司(Elgin,IL)的仪器,商品名TRI-COR 805A/806H型表面分析系统(TRI-COR MODEL 805A/806H SURFACE ANALYSIS SYSTEM),按照“TriCor Systems WGLOSS 3.4 1805A/806H型表面分析系统参考手册”(1996)的方法来测定本发明衣壳的表面光泽度,其内容纳入本文作参考,改进如下。
此仪器采用CCD照相机探头,利用平面扩散光源,将样品与参照标准品作比较,测定60度入射角时的平均光泽度值。其操作中,该仪器产生暗淡级别影象。当出现更明亮的像素时表明给定位点存在更多光泽。
此仪器也加入了利用分组方法定量测定光泽的软件,即将类似亮度的像素分组进行平均。由用户确定“全范围百分比”或“理想百分比”的设置(也称为样品分组百分比设置),以确定超过域值(认为是一组和该组的平均)的最高像素部分。本文中“域值”定义为不包括在平均光泽值计算中的最大光泽值。因此,背景光泽,或样品的非发光泽表面被排除在平均光泽值计算之外。此方法见:K.fegley和C.Vesey,”片剂形状对高光泽膜包衣系统的作用”中所述,可从 www.colorcon.com获得(2002.3.18),本文纳入作为参考,可用其尽量减少不同衣壳形状产生的影响,和以工业界相当的公制单位报告。(选择50%样品组设置作为表面粗糙度测定最佳接近值模拟数据设置。)
用校准参考平面(190-228;294度标准,无遮光板,旋转0,深度0)初步调校此仪器后,可用购自McNeil-PPC有限公司的商品名为Extra Strength TYLENOLGelcaps的凝胶包衣囊片产生标准表面光泽度的测定值。可测定这种凝胶包衣囊片样品的平均光泽度值,同时采用25mm全视野遮光板(190-280),和使该仪器形成以下设置:
旋光:0,
深度:0.25英寸,
粗域值:95,
%全范围:50%,
折射指数:1.57。
然后测定参考标准品的平均表面光泽度值。
可按相同方法分别测定各衣壳样品。
衣壳的重量宜为核仁重量的约10-400%。在用无溶剂模制工艺制备的衣壳实施例中,衣壳的重量通常是核仁重量的约50-400%,如核仁的约75-400%、约100-200%。在用基于溶剂的模制工艺制备的衣壳实施例中,衣壳的重量通常是核仁重量的约10-100%,优选为核仁重量的约10-60%。
当所述剂型量与液体介质如水、胃肠液等接触时,所述衣壳提供了活性成分的溶解延迟至少约3小时,或至少约4小时,或至少约6小时,或至少约12小时。此延迟期通常受衣壳的厚度、组成或其组合所控制。一实施例中,此延迟期限不依赖于溶液介质或液体环境的pH值。例如,活性成分在0.1N HCI中溶解的平均迟后时间基本上与活性成分在pH5.5缓冲系统中溶解的平均迟后时间没有不同。
可用于本发明的衣壳厚度通常为约50-4000微米。在用无溶剂模制工艺制备的衣壳实施例中,衣壳通常的厚度是约500-4000微米,如约500-2000微米、约800-1200微米。在用基于溶剂的模制工艺制备的衣壳实施例中,衣壳通常的厚度不到约800微米,如约100-600微米、约150-400微米。
本发明一实施例中,所述衣壳还含有至少一种与核仁所含活性成分相同或不同的活性成分。
本发明另一实施例中,所述剂型中所含的至少一种活性成分显示延迟的暴发性释放方式。“延迟的暴发性释放方式”指所述剂型在病人吞食后,其中的具体活性成分按预定时间延迟释放,该迟后期(“迟后时间”)之后是活性成分的快速(立即)释放。本发明的衣壳提供了延迟期,优选活性成分不以延迟后的暴发性方式释放。此类实施例中,延迟后暴发性释放的活性成分通常包含在核仁或其一部分中。这些实施例中,核仁可用压制或模制法制备,配制成立即释放,这样在与溶液介质接触时核仁易于溶解。这类实施例中,核仁优选含有崩解剂,和任选地含有其它赋形剂,如填充剂,或选自水可溶性或低融点材料、表面活性剂和保湿剂的热可塑材料。这些实施例中,迟后期后暴发性释放的活性成分的溶解应符合USP含该活性成分即释片剂的规定。例如,对于扑热息痛片剂,USP规定,在pH5.8磷酸缓冲液中,用USP装置2(浆叶),50rpm后30分钟内,,剂型中含的扑热息痛至少80%释放。对于布洛芬,USP规定,在pH7.2磷酸缓冲液中,用USP装置2(浆叶),50rpm后60分钟内,,剂型中含的扑热息痛至少80%释放。见USP24,2000版。19-20和856页,1999。
本发明另一实施例,所述剂型含有的至少一种活性成分显示延迟和持续释放方式。“延迟然后持续释放方式”指病人吞食所述剂型后,其中具体活性成分的释放按预定时间延迟了,此段时间延迟之后是该活性成分的持续(延长、延时或延迟)释放。本发明的衣壳提供了迟后期,优选基本上以延迟后持续方式完全释放活性成分。这类实施例中,核仁的作用可能是,例如可腐蚀性基质、或可扩散性基质或渗透泵。在核仁或其一部分是扩散性基质,活性成分以持续、伸长、延长或延时方式通过其释放的实施例中,核仁部分宜含有选自不溶性可食用材料和孔前体材料的调节释放的赋形剂。或者,在用模制动器法制备核仁的实施例中,热可逆载体的作用是溶解活性成分和形成活性成分释放的孔或通道。在核仁或其一部分是腐蚀性基质,活性成分以持续、伸长、延长或延时方式在其中扩散的实施例中,核仁部分宜含有选自可膨胀可腐蚀性亲水材料、pH-依赖性聚合物及它们的组合的调节释放性可压缩或可模制性赋形剂。
一实施例中,所述衣壳不是施加在核仁上的压制包衣。
本发明将通过以下实施例进行阐明,但这些实施例不以任何方式限制本发明。
