    • A high molecular weight drug is transdermally administered by applying a polymer skin enhancer and a drug active to the skin of the patient. The drug active has a molecular weight of above 500 daltons. The drug may be encapsulated or the drug solution may be partly encapsulated and partly free. The skin enhancer is preferably polyvinylpyrrolidone (PVP) and it is mixed at between 7 and 35% of the drug. A gelling agent may be optionally added at up to 20% by volume. The chemical system is preferably administered via a multidose transdermal drug patch assembly which includes a drug-impervious support impressed to form a series of compartments. Each compartment is a reservoir for a unit dose of a drug active to be transdermally administered. The support is adhesively secured to the skin of a patient. Individual devices are provided for resealably enclosing the drug active in each of the reservoirs. The individual enclosing devices are removable to release the unit dose into contact with the skin of the patient and are actuable to control the transdermal absorption of the drug actives. The drug may also be administered in a creme.
    • 通过将聚合物皮肤增强剂和药物活性剂施用于患者的皮肤来透皮施用高分子量药物。 药物活性物质的分子量高于500道尔顿。 药物可以被包封或药物溶液可以被部分包封并且部分游离。 皮肤增强剂优选为聚乙烯吡咯烷酮(PVP),并且其在药物的7至35%之间混合。 可以任选地以高达20体积%添加胶凝剂。 化学系统优选经由多剂量透皮药物贴剂组合物施用,该药物贴剂组合物包括被压入以形成一系列隔室的药物不渗透性支持物。 每个隔室是用于经皮给药的药物活性单位剂量的储存器。 支撑体粘合地固定在患者的皮肤上。 提供单个装置用于可重新密封地包围每个储存器中的活性物质。 单独的包封装置是可移除的,以释放单位剂量与患者的皮肤接触,并且可致动以控制药物活性物质的透皮吸收。 药物也可以在奶油中施用。

    • A drug delivery system for transdermally delivering drugs through a given skin area is provided. The delivery system comprises a collapsible container for containing the drug. The container has a drug release opening. A displaceable member is in engagement with the container for expelling the drug from the container via the release opening. A driver is connected with said displaceable member so as to drive the same towards the collapsible container. Conduits are disposed between the release opening and the skin area for conducting the drug to the skin area. An ultrasonic transducer is disposed in the general conduit area for generating ultrasonic waves aimed at the skin area. An ultrasonic waveform generator drives the transducer and an electric control circuit is connected to the flow control for electrically activating the flow control.
    • 提供了通过给定皮肤区域透皮递送药物的药物递送系统。 递送系统包括用于容纳药物的可折叠容器。 容器具有药物释放口。 可移动构件与容器接合,用于经由释放开口将药物从容器排出。 驾驶员与所述可移动构件连接,以将其驱动到可折叠容器。 导管布置在释放开口和皮肤区域之间,用于将药物导入皮肤区域。 超声换能器设置在通用导管区域中,用于产生针对皮肤区域的超声波。 超声波波形发生器驱动换能器,并且电控制电路连接到用于电激活流量控制的流量控制。
