前言
发明背景
组织炎症是多种生理事件交叉作用的结果。与组织损伤有关的皮肤炎症可以由各种皮肤疾病造成,例如湿疹、牛皮癣、脂溢性皮炎、接触性皮炎、变应性皮炎等。炎症还与紫外线或热灼伤、某些微生物的攻击、昆虫叮咬、螫伤等造成的组织损伤有关。深层结构、肌肉、腱、囊和关节的与组织损伤有关的炎症可以由躯体创伤,例如扭伤、劳损、挫伤、剧烈运动等造成。这些炎症可导致滑囊炎、腱炎和肌肉酸痛。炎症还与下列原因造成的组织损伤有关;代谢障碍,例如痛风;免疫障碍,例如类风湿性关节炎;或与年龄有关的变化,例如骨关节炎。
炎症的症状是红斑(红肿)、水肿(肿胀)、发热、疼痛和机能丧失。组织损伤的直接后果是释放出作为炎症介体的某些化学物质,即,这些物质引起和强化造成红肿、肿胀、疼痛和发热的事件。这些化学物质的实例是组胺、5-羟色胺和激肽。
目前,各式各样的局部用贴剂被用来减轻疼痛,例如肩酸痛、背痛、发炎等等。这些局部用贴剂的一般的活性成分是作为降温作用抗刺激剂的甲醇、樟脑和薄荷油。但是,这些降温剂的一个问题是其强烈的气味,这会令人讨厌。
因此,一直有头趣研发能够有效治疗患有以上病症的患者的新的局部用障温剂组合物。

局部用贴剂
如上所述,本发明涉及一种无气味的生理降温剂的局部用贴剂。本发明的局部用贴剂的特征是在凝胶粘合性基料中含有有效数量的无气味生理降温剂。图1提供了根据本发明所述的一种局部用贴剂的示意图。由图1可见,该代表性的局部用贴剂10包括存在于载体14之上一种凝胶粘合性基料12。现在更详细地说明所有这些组分。
作为保持层起作用的凝胶粘合性基料由存在于,例如,溶解于或分散于基料中的无气味的生理降温剂和粘合性凝胶基料组成。“生理降温剂”是指一种药物,当它与治疗对象的皮肤接触时,会以与甲醇 的降温作用相似的方式,赋予受治疗者一种降温的感觉或效果。“无气味”意味着该药物的气味比甲醇气味的刺激性小。

WS-23:(2-异丙基-N,2,3-三甲基丁酰胺),Millennium Chemical产品
在某些实施方案中,降温剂是一种无环的酰胺,代表性的无环酰胺包括下式化合物:
其中
R1、R2和R3各为C1-C5烷基,合起来具有总计至少3个,例如约3-10个,包括约5-10个碳原子;R’是C1-C5烷基,C1-C8羟基烷基,或最高达8个碳原子的烷基羧基烷基。在这一基团中,R1在代表性的实施方案中是甲基、乙基或正丙基,R2和R3中的一个或两个都是在相对于标有*号的碳原子的α位或β位支化。在代表性的实施方案中,降温剂是N,2,3-三甲基-ω-异丙基丁酰胺(也称作WS-23;三甲基异丙基丁酰胺,CAS #51115-67-4)。
以上化合物可以用任何合适的方案制备,在美国专利4,296,255中描述了代表性的制备方案。
其它重要的代表性的无气味生理降温剂包括但不限于:里哪醇,香味醇,羟基香茅醛,WS-3(Millennium Chemical),Flescolat MGA(Haarman & Reimer),Frescolat ML(Haarmann & Reimer),PMD 38(Takasago),Coolact P(Takasago)和Cooling Agent 10(Takasago)等。
粘合性凝胶基料中存在的无气味生理降温剂的数量,如下面所详述的,当敷贴在治疗对象的皮肤表面上时,足以向其施予有效数量的该降温剂。在很多实施方案中,粘合性凝胶基料中无气味生理降温剂的含量为约0.1-15.0%(w/w),有时为约0.5-10.0%(w/w),例如约1.0-8.0%(w/w),包括约2.0-7.0%(w/w)。
如上所述,包含降温剂的粘合性凝胶基料由水溶性高分子量物质、水和水剂组成。在某些实施方案中,粘合性凝胶基料还包含一种助溶剂,例如一种有机助溶剂。现在更详细地分别描述各个组分。
重要的水溶性高分子量物质包括水溶性聚合物,其中重要的聚合物包括但不限于:明胶,淀粉,琼脂,甘露聚糖,藻酸,聚丙烯酸,聚丙烯酸钠,糊精,甲基纤维素,甲基纤维素钠,羟丙基纤维素,羧甲基纤维素钠,羧甲基纤维素,羧基乙烯基聚合物,聚乙烯醇,聚乙烯吡咯烷酮,阿拉伯树胶,黄蓍胶,刺梧酮树胶,以及淀粉丙烯酸酯共聚物或其它的淀粉丙烯酸钠接枝共聚物。这些聚合物的金属盐及通过有机或无机交联剂形成的交联产物也在考虑之内。这些水溶性聚合物可以用来发挥出在粘合性凝胶组合物中使用的其它起始物的性质和特点,实际上可以单独使用或是两种或多种联合使用。粘合性凝胶基料中的水溶性高分子量物质的含量一般是约0.5-20%,例如约2-20%(w/w)。
任何合适的水都可以作为水组分使用,但特别重要的是蒸馏水或离子交换水等,它们在本发明的很多实施方案中是优选的。凝胶粘合剂中的水含量足以使凝胶粘合剂具有所要求的物理性质,改善皮肤的角质层或角质化层的溶胀,从而改善活性剂的透过或穿透能力,其中在凝胶组合物内的水量一般为约10-80%,例如约30-60%(w/w)。
本发明的粘合性凝胶组合物的保水剂或持水剂是能够至少减小粘合性凝胶基料中包含的水的蒸发,从而使粘合性凝胶基料中的水含量在制剂的贮存和使用期间保持在即使不是恒定,至少也是基本上恒定水平的任何试剂。在本发明组合物中可以使用一种或多种保水剂,其中保水剂在粘合性凝胶基料中的含量为约1-70%,例如约10-60%重量。合适的保水或持水剂包括但不限于一种或多种多价或多羟基的糖 或醇,例如甘油、山梨醇、丙二醇、二甘醇、1,3-丁二醇,以及乙二醇等。
此外,本发明的凝胶基料组合物还可以包括一种助溶剂,该助溶剂一般是有机助溶剂。重要的助溶剂的实例包括但不限于:N-甲基-2-吡咯烷酮,二乙基甲苯酰胺,乙醇,甲醇,聚乙二醇(例如,低分子量的聚乙二醇,如PEG 600或者更低,例如,500、400、300、200、100等及其共混物)和肉豆蔻酸异丙酯等。助溶剂可以由单一组分或是由两种或多种组分结合构成。
再者,除了上述成分以外,需要时还可以适当地混入通常的局部用水溶性贴剂中使用的各种添加剂,包括无机物质,例如高岭土,膨润土和二氧化钛;防腐剂,例如对羟基苯甲酸酯;阴离子、阳离子和非离子型表面活性剂;金属铝交联剂,例如氯化铝、干燥的氢氧化铝凝胶和氨基乙酸二羟基铝;油类,例如西蒙得木油和蓖麻油;螯合剂,例如EDTA;pH调节剂,例如苹果酸、酒石酸和二异丙醇胺;醇类,例如乙醇;保湿剂,例如透明质酸、芦荟提取物和尿素;以及其它的香料和着色剂。
凝胶基料组合物的pH一般处在生理上可接受的范围之内,pH通常可以为约4.0-7.0,例如约4.0-6.0。
如上所述,含有一种或多种活性成分的粘合性凝胶组合物通常处在载体或衬材上。载体一般由能适应人体的运动的柔性材料制成,包括例如各种非织造织物、织造织物、氨伦纤维、法兰绒,或这些材料与聚乙烯薄膜、对苯二甲酸乙二醇酯薄膜、聚氯乙烯薄膜、乙烯-乙酸乙烯酯共聚物薄膜、聚氨酯薄膜等的层压件。
除了粘合性凝胶组合物和载体层之外,本发明的局部用贴剂还可以包括一个处在凝胶层表面上与衬材相对的防粘膜16,它保护凝胶层与环境隔离。该防粘膜可以任何合适的材料,代表性的防粘膜包括聚酯,例如PET或PP等。
在很多实施方案中,贴剂是装在密封的包装里。通常,该密封包装由包装材料制成,材料中包括一个由能阻止湿汽、氧和其它试剂通过的薄层,即,包装内包括一种湿气/氧阻挡材料。任何合适的阻挡材料均可使用,重要的阻挡材料包括金属层,例如铝、在很多实施方案中阻挡层是铝层。这种阻挡层的厚度足以提供阻挡功能,其厚度一般为约5-15μm,通常是约6-10μm。在很多实施方案中,包装是该阻挡层与一个或多个其它层,例如聚合物层、纸层等,组合形成的层压件。可以与本发明的贴剂一起使用的一种代表性的含铝包装由Dainippon Printing Co.,Ltd.(Kyoto,Japan)销售。
局部用的贴剂可以用任何合适的方案制造。一种适合制造本发明贴剂的方案包括通过将上述成分均匀混合制备凝胶粘合糊体,然后将该糊体涂在载体上,接着将所形成的产品切割成指定尺寸以得到所要的局部用贴剂。随后将得到的局部用贴剂用如上所述的含有铝层的包装材料热封,一般是一个包装内几片,以得到密封的局部用贴剂。关于制造方案的更详细的说明,参见美国专利5,827,529,其内容在这里结合作为参考。
在一项代表性的制备方案中,本发明中使用的基料的制备方法是:采用任何合适的方案,将上述成分用混合机均匀掺混成糊,然后利用涂胶机将其铺展在衬底或载体材料上。如上所述,载体材料可以是例如纸,或是由PET或PP或其它一些聚酯纤维制成的织造或非织造织物。为了保护,其表面随后用聚酯例如PET或PP防粘膜覆盖。这些步骤示例说明在图2中。
如下面更详细叙述的,在代表性的实施方案中,水凝胶贴剂组合物是自粘的,即,固有粘性的,因此可以固定在皮肤伤口上的某个位置,即,可脱除地粘结在指定的皮肤伤口上和/或其周围,无需使用另外的粘合剂或其它手段将贴剂保持就位。例如,水凝胶组合物基质本身可以是粘合剂。
在代表性的实施方案中,正如使用日本工业标准(JIS)Z-0237粘合剂强度测定规程(例如见美国专利申请No.11/002,998题目“Methods and Compositions for Treating SKin Wounds”,2004年12月1日提交;其内容在这里结合作为参考)所确定的,水凝胶组合物是粘合剂。一种指定的水凝胶组合物,如果在这一规程中能停住至少No.3大小的球,例如至少约No.4大小的球,包括至少约No.5大小的球,则被认为是粘合剂。在某些实施方案中,该组合物的粘合性足以停止No.6或更大的球,例如No.7或更大的球,如No.8或更大的球,例如No.9或更大的球。在某些实施方案中,本发明组合物的粘结性有差动性,它们对非生命体的粘结性比对生命体的要大。
在另一些实施方案中,本发明的水凝胶贴剂组合物可以用另外的粘合剂,例如粘合性衬材等或者固有的粘接性与另一种不同的粘合手段相结合,保持在皮肤伤口周围的固定位置。
一些水凝胶贴剂组合物可以适合并用来和本发明一起使用。适合与本发明一起使用的代表性的水凝胶组合物包括但不限于在以下专利中描述的那些:PCT国际出版物:WO 02/078757和WO 02/078756,以及美国专利:5,120,544;5,160,328;5,270,358;5,423,737;5,476,443;5,489,262;5,501,661;5,827,529;6,039,940;6,096,333;6,214,374;6,296,869;6,348,212;6,455,065;其内容结合在本文中作为参考。
然后将所形成的产品切成指定的尺寸以得到所要求的局部用贴剂组合物。该贴剂的形状可以变化,其中代表性的形状包括正方形、矩形、椭圆形、圆形等。贴剂的尺寸也可以变化,在很多实施方案中尺寸范围是约1-200cm2,并且在很多实施方案中是约10-180cm2,通常为约100-150cm2,例如140cm2。最终的局部贴剂中的基料重量可以是约300-1500g/m2,例如约600-1200g/m2。然后将这种水溶性局部用贴剂利用热封方法包装在含有一铝层的包装材料内,得到如图3所示的最终产品。
应当指出,以上的制造规程只是典型代表。任何能够制造本发明局部用贴剂的合适规程均可采用。
贴剂的使用方法
本发明的贴剂可用于向治疗对象,特别是向治疗对象的皮肤,局部输送一种降温剂。在实施本发明时,贴剂可以施用于任何合适的局部部位。重要的局部部位包括但不限于:臂、腿、躯干、头等。敷贴之后被局部用贴剂覆盖的表面积必须足以提供所要求数量的药物施用,在很多实施方案中是约1-200cm2,并且在很多实施方案中是约10-180cm2,通常为约100-150cm2,例如140cm2。
在代表性的实施方案中,释放出所要求数量药物的时间一般不超过约48小时,通常不超过约24小时。然而,制剂在敷贴部位上保持的时间,在很多实施方案中至少为约30分钟,通常至少为约1小时。
在实施本发明的方法时,可以在指定的一段时间里,例如在治疗病症的过程中,敷贴局部用贴剂一次或多次,其中若是在指定时间内施用多个贴剂,则用药的时间表可以是每天,每周,每双周,每月等。
上述贴剂和方法可用于希望对治疗对象施用一种生理降温剂的任何场合。除了基它用途之外,按照本文所述的本发明方法局部施用降温剂,对于治疗炎症、疼痛等,包括在本申请前言部分所述的疾病,是有效的。通常,治疗对象是“哺乳动物”,这些术语是广义地用来描述属于哺乳类动物的生命体,包括食肉目(例如犬和猫)、啮齿目(例如小鼠、豚鼠和小鼠)和灵长目(例如人、黑猩猩和猴)。在很多实施方案中,宿主将是人。
在代表性的实施方案中,本发明方法可用于治疗病症。治疗是指至少减轻与折磨宿主的病理条件有关的症状,其中减轻是在广义上使用,指的是与所治疗的病理状态和与其有关的副反应的某个参数,例如症状,其大小至少有所减小。因此,治疗也包括其中病理状态,或者至少是与其有关的症状,被完全抑制,例如阻止发生,或者被停止,例如终止的情形,从而宿主不再患有该病理状态,或者至少是作为该病理状态的特征的症状。因此,治疗包括治愈和控制病症这两种情形。试剂盒
还提供了试剂盒,本发明的试剂盒至少包括上述的一个或多个贴剂。试剂盒中的本发明局部用贴剂可以如上所述地放在包装内。试剂盒的局部用贴剂通常处在单独的袋或类似的容器内,以便保存贴剂的组合物直至使用。本发明的试剂盒一般还包括如何使用该贴剂的说明书,说明书中通常包括关于贴剂用于何处,用药时间表等信息。说明书一般是记录在合适的记录介质上。例如,可以将用药说明印在基底上,例如纸或塑料等。因此,说明书可以作为包装内插件置于试剂盒内,在试剂盒或其组件的容器的标干中(即,与包装或次级包装一起)等等。在其它实施方案中,说明书是以电子存储数据文档的形式提供在合适的计算机可读存储介质上,例如光盘、软盘等。
提供以下的实施例和对照例作为示例说明,而不是作为限制。
