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.
Abstract: The present invention relates to carboxyalkyl dipeptides which are inhibitors of angiotensin-converting enzyme and are useful as antihypertensive agents and in the treatment of congestive heart failure.The compounds of the present invention are compounds of the formulae ##STR1## and the pharmaceutically acceptable salts thereof, wherein R and R.sup.6 are the same or different and are hydroxy or lower alkoxy;R.sup.1 is benzyloxylower alkyl or benzylthiolower alkyl;R.sup.2 is benzylthiomethyl, 2-phyenylethylthiomethyl, napthylmethylthiomethyl, methylbenzylthiomethyl, 2-(carboxyphenyl)ethyl or 2-(alkoxycarbonylphenyl)ethyl) andR.sup.3 is hydrogen, lower alkyl or aminolower alkyl.
