本申请要求2003年10月23日提交的美国临时申请号60/514,533 This application claims filed October 23, 2003 of US Provisional Application No. 60 / 514,533
的权利。 s right.
本发明涉及阻止核酸降解的方法和组合物。 The present invention relates to a nucleic acid to prevent degradation methods and compositions. 更具体地说，本发明涉及涂覆透皮释放此类核酸的《敬喷射体(microprojections)的方法和组合物。 More particularly, the present invention relates to methods and compositions for transdermal release coating such nucleic acids "King jetting body (microprojections) a.
最通常通过口服或注射给予活性剂(或药物)。 Most typically by injection or oral administration of the active agent (or drug). 遗憾的是，当口服时，许多活性剂完全无效或疗效大幅降低，因为它们在进入血流前没有被吸收或受到不利影响，因而不具有需要的活性。 Unfortunately, when administered orally, many agents are completely ineffective or have radically reduced efficacy because they are not absorbed or are adversely affected before entering the bloodstream, and therefore does not have the desired activity. 在另一方面，直接将药物注射到血流中，虽然可保证给药期间不发生变化，但它是困难、不方便、痛苦和不舒适的过程，它有时导致患者依从性差。 On the other hand, the direct injection of the drug into the bloodstream, while assuring did not change with the administration, but it is difficult, inconvenient, painful and uncomfortable procedure which sometimes results in poor patient compliance.
作为备选方式，透皮释药"^是供无需通过皮下注射、静脉输注或口服给予生物活性药物的方法。与口服释药相比，透皮释药避免了消化道的苛刻环境，绕过胃肠药物^a谢，减少首过效应，避免由消化酶和肝酶造成的可能的失活。相反，消化道在透皮给药期间不与生物活性药物接触。许多药物，例如阿司匹林确实对消化道有副作用。 As an alternative, transdermal delivery "^ administering a method without the biologically active agent by subcutaneous injection, intravenous infusion or for oral administration compared with oral drug delivery, transdermal drug delivery avoids the harsh environment of the digestive tract, about ^ a gastrointestinal drugs through Xie, reducing the first pass effect, to avoid possible deactivation caused by digestive and liver enzymes. Conversely, the digestive tract is not in contact with the biological activity of the drug during transdermal administration of many drugs, such as aspirin does gastrointestinal side effects.
本文中使用的通用术语"透皮"是指药物穿过皮肤层。 Generic term used herein, "transdermal" refers to a drug through the skin layer. 词"透皮"是指通过局部组织或全身循环系统的皮肤释放药物(例如核酸或其它治疗药物），而基本上不切开或刺穿皮肤，例如用手术刀切开或用皮下注射针刺穿皮肤。 The word "transdermal" refers to the release of the drug (e.g., nucleic acid or other therapeutic agent) through the local tissue or systemic circulatory system of the skin, but does not substantially cut or pierce the skin, for example with a hypodermic needle or scalpel through the skin. 最外面皮肤层由脂双层包围的平坦、充满角蛋白纤维(即角质细胞)的死细胞形成。 The outermost layer of the skin surrounded by lipid bilayers flat, dead cells filled with keratin fibers (i.e., keratinocytes) are formed. 脂双层的高度条理结构给角质层提供相对不渗透的特性。 This highly-ordered structure of the lipid bilayer to provide a relatively impermeable character to the stratum corneum of. 因此，透皮释药系统面临的最主要的问题之一是通过皮肤部分转运药物。 Therefore, one of the most important issues facing the transdermal delivery system is part of the transport drugs through the skin.
透皮释放药物包括通过被动扩散和通过包括电(例如离子电渗疗法)和超声（例如超声导入法)的外界能源的释放。 Transdermal delivery of drug by passive diffusion and release comprises by comprising an electrical (e.g., iontophoresis) and ultrasound (e.g., phonophoresis) external energy. 虽然药物确实穿过角质层和表皮扩散，但由于上述原因，通过角质层扩散的速率时常为限速步骤。 While drugs do diffusion through the stratum corneum and epidermis, but the reasons mentioned above, the rate of diffusion through the stratum corneum is often the limiting step. 为达到治疗剂量，许多化合物需要比可通过简单被动透皮扩散达到的释药速率更高的释药速率。 In order to achieve a therapeutic dose, a number of compounds may be required than the diffusion rate of a higher release rate of release achieved by simple passive transdermal.
增加被动透皮扩散药物通量的一个普通方法涉及用皮肤渗透促进剂预处理皮肤或与皮肤渗透促进剂共释放。 A common method of increasing the passive transdermal diffusional agent flux involves pre-treating the skin to promote skin permeation and skin penetration enhancers or co-delivering. 当渗透促进剂施用于释放药物的体表面时，渗透促进剂促进通过其中的药物通量。 When the penetration enhancer is applied to the surface of the release of the drug, permeation enhancers through the drug flux therethrough. 但是，这些促进透皮药物通量的方法的效果有限，尤其对于大分子。 However, these methods are limited effects of enhancing transdermal agent flux, especially for large molecules.
主动转运系统用外界能源帮助药物通量穿过角质层。 Active transport system to help the flux of drug through the stratum corneum by external energy. 这种促进透皮释药方法的一种称为"电转运"。 Such promote transdermal delivery method called "electrotransport." 该机理是利用电位，电位导致用电流帮助药物通过体表，例如皮肤转运。 This mechanism is the use of a potential, a potential cause current to aid drug through a body surface, such as skin transport. 其它主动转运系统使用超声（超声导入法)和热能作为外界能源。 Other active transport systems use ultrasound (phonophoresis) and heat as the external energy.
还已开发出许多技术和系统，它们机械渗透或破坏最外面皮肤层，从而开辟出进入皮肤的通路，以便提高透皮释放的药物量。 It has also been many techniques and systems developed to mechanically penetrate or disrupt the outermost skin layers thereby creating pathways into the skin in order to enhance the amount of agent being transdermally delivered. 例如皮肤破皮装置或划痕器，它们通常提供用于擦伤皮肤或在施用部位制 Such as skin or broken skin streaker device, they are usually provided for braking or abraded skin at the site of administration
备小切口的许多齿或针。 Preparation of a small incision plurality of teeth or needles. 例如如美国专利号5,487,726中公开的疫苗在皮肤上局部使用，或如美国专利号4,453，926、4,109,655和3,136,314 公开的以润湿液体应用于划痕器的齿上。 E.g. vaccine disclosed in U.S. Patent No. 5,487, 726 for topical use on the skin, teeth or as U.S. Patent Nos. 4,453,926,4,109,655 and 3,136,314 disclosed a liquid applied to wet streaking.
已建议划痕器用于透皮释放疫苗，部分原因是只需极少量疫苗释放进入皮肤即能有效使患者免疫。 Has been proposed for transdermal delivery scratches vaccine, in part because only a very small amount of vaccine delivered into the skin that is effective in immunizing the patient. 另外，释放的疫苗量不是特别重要，因为过量也能达到符合要求的免疫。 In addition, the amount of vaccine delivered is not particularly important, because the excess can achieve immunity meet the requirements.
与使用划痕器释放活性药物有关的主要缺点是难以测定透皮药物通量和所得释放剂量。 The main disadvantage in using a scarifier to release the active drug is difficult to determine the relevant transdermal agent flux and the resulting release dosage. 另外由于偏转和抵抗刺入的皮肤弹性、变形和回弹特性，在渗透皮肤时，微小刺入元件通常不能均匀地渗透皮肤和/或擦除药物的液体涂层。 Further since the elasticity of the skin to deflect and resist, deforming and resilient nature of the piercing, when the skin permeability, the tiny piercing elements often do not uniformly penetrate the skin and / or liquid coating erased drug.
