摘要:
The invention provides a local concentration management system (LCMS) for delivery of highly concentrated therapeutic agent formulations. The LCMS comprises a device comprising an elongate body defining a lumen between its proximal and distal ends, and a diffuser element, a dilutor element, or both. The diffuser element, which is selectively permeable to the agent, is operatively associated with the elongate body so that agent flows through the elongate body, and into and through the diffuser element to exit the system. The dilutor element can be operatively associated with the system to be in fluid communication with the elongate body lumen, a diffusion space defined by a diffuser element inner wall, or both. The dilutor element is selectively water permeable, but substantially impermeable to agent, to provide for dilution of the agent during transit through the system. The LCMS system is designed to disperse and/or dilute the drug delivery stream.

摘要:
Composition of matter for application to skin to administer fenoldopam by permeation through the skin, the composition comprising fenoldopam to be administered, at a therapeutically effective rate, in combination with a permeation enhancer or mixture. Also disclosed are drug delivery devices and methods for the transdermal administration of fenoldopam for the treatment of hypertension, congestive heart failure, and chronic and acute renal failure.

A composition of matter for application to a body surface or membrane to coadminister an estrogen and progesterone by permeation through the body surface or membrane, the composition comprising, in combination, the estrogen and progesterone to be administered, in a therapeutically effective amount; and a permeation-enhancing mixture comprising a monoglyceride or a mixture of monoglycerides, and a lactate ester or a mixture of lactate esters at specific concentrations. The composition of matter is used to provide hormone replacement therapy to a woman.

The present invention provides compositions and systems for the transdermal administration of a drug together with glycerol monolinoleate as a permeation enhancer. An example of a delivery system of the invention is a system (20) having a drug reservoir (22) containing together a drug to be delivered and glycerol monolinoleate permeation enhancer. Reservoir is sandwiched between a backing layer (24) and an in-line contact adhesive layer (28).
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:
The present disclosure provides a biodegradable drug delivery composition including a vehicle and an insoluble component comprising beneficial agent dispersed in the vehicle. Typically, the composition is not an emulsion, but has a low viscosity and further provides for minimized initial burst and sustained release of the beneficial agent over time. Also provided, are kits including the biodegradable drug delivery composition or components thereof, as well as methods of making and using the biodegradable drug delivery composition.
