  • Patent number: 4824676
    Abstract: A method of enhancing transdermal delivery of a pharmaceutically active drug from a transdermal delivery system as well as a transdermal delivery system capable of providing a desirable flow interface between the delivery system and the skin surface are disclosed. The method involves pre-treating an area of skin with an anticholinergic agent in an amount sufficient to have a local antisecretory effect on the area treated, such amount being insufficient to cause systemic effects; and applying the transdermal delivery system to the pre-treated area. The delivery system of the present invention is comprised of a carrier means, a pharmaceutically active drug and an anticholinergic agent. With both the method and the delivery system, the anticholinergic agent is preferably a quaternary ammonium salt which is itself transdermally delivered to the area beneath the delivery system in an amount sufficient to suppress perspiration in that area.
