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: A long acting diltiazem formulation is disclosed that comprises more than 35 percent by weight of a swellable hydrophilic polymer.Release rate is also controlled by the application of diffusion controlled membrane to the matrix tablet containing swellable hydrophilic polymers. The diffusion rate through the membrane depends upon the composition or ratio of hydrophilic to hydrophobic coating agent.
