    • A transdermal electrotransport drug delivery device having an anode, a cathode and a source of electrical power electrically connected to the anode and the cathode. At least one of the anode and the cathode includes an electrode and a reservoir comprised of a housing composed of a polymeric material and an aqueous medium in contact with the housing. The aqueous medium includes (i) a drug or an electrolyte salt or a mixture thereof, (ii) propylene glycol, and (iii) an antimicrobial agent in an amount sufficient to inhibit microbial growth in the aqueous medium. The propylene glycol prevents the antimicrobial agent from being adsorbed by other materials used in the construction of the delivery device. A process for preparing a transdermal electrotransport drug delivery device is also provided.
    • 具有电连接到阳极和阴极的阳极,阴极和电源的透皮电运输药物递送装置。 阳极和阴极中的至少一个包括电极和由包含聚合物材料的外壳和与外壳接触的水性介质的容器。 水性介质包括(i)药物或电解质盐或其混合物,(ii)丙二醇,和(iii)足以抑制水性介质中微生物生长的量的抗微生物剂。 丙二醇防止抗微生物剂被用于构建输送装置的其它材料吸附。 还提供了一种制备透皮电转运药物递送装置的方法。
