    摘要: A device for the transdermal administration of a drug comprising a microporous tie layer located between the drug reservoir and the contact adhesive. The tie layer eliminates blooming and delamination and has no appreciable adverse effect on either the drug flux or release rate from the device.

    摘要: A diffusional drug delivery device is described which can provide for delayed onset of therapeutic effect and for delivery of the therapeutic agent in predetermined temporal patterns at optimum rates. Delay means are provided between the agent reservoir and the surface through which the agent is released by diffusion to delay the release of agent at a therapeutic rate for predetermined times after application. Suitable means include a delay membrane disposed between the releasing surface and the agent reservoir, which membrane is preferably free of undissolved agent and/or is initially impermeable to the agent and thereafter becomes permeable. One or more agent chambers defined by one or more of such membranes may be provided, whereby agents are released in predetermined temporal patterns at optimal release rates. Delayed permeability enables programmed washout periods to be obtained from the sequential and concurrent application of devices for the administration of drugs, such as nitrates, to which patients may develop a tolerance on continuous administration over extended time periods.

    摘要: This invention is directed to a novel formulation for effectively utilizing hydrophobic permeation enhancers for the increased permeability of active agents through the skin or mucosa along with reduction of the lag time between application of the active agent and attainment of a therapeutically effective agent flux, with little or no irritation to the host. The invention is directed to compositions containing a hydrophobic permeation enhancer, which permeation enhancer has been micronized and stabilized in an inert carrier such as water. These compositions can be combined with a biologically active agent to provide enhanced permeability of the active agent to the skin or mucosa.

    摘要: A diffusional drug delivery device is described which can provide for stability of the adhesive and system components, elimination of the initial burst of drug and hence irritation, and to provide for delayed onset of therapeutic effect along with delivery of a therapeutic agent at an optimum rate. The therapeutic agent in a first form which is suitable for storage, and the anhydrous activating means are inert when in an anhydrous environment. Moisture activates the system whereby the activating means provides an acidic or basic solution and the first form of the therapeutic agent is converted to a second form which is suitable for absorption through the skin or mucosa.

    摘要: The present invention is directed to the transdermal administration of a drug together with a suitable amount of an acyl lactylate permeation enhancer. The invention includes a transdermal drug delivery device comprising a matrix adapted to be placed in drug- and- permeation enhancer-transmitting relation with a skin site. The matrix contains sufficient amounts of an acyl lactylate permeation enhancer and drug, in combination, to continuously administer drug to the systemic circulation of a patient at a therapeutically effective rate. The invention is also directed to compositions and methods for transdermal administration of a drug together with an acyl lactylate permeation enhancer, alone or in combination with other enhancers.
