摘要:
The invention relates to a transdermal therapeutic system for the controlled release of water-soluble pharmaceutical active ingredients from an aqueous phase, comprising an occlusive back layer, a central device facing the skin for releasing the agent, an adhesive layer concentrically surrounding the dispensing device and a removable protective film. Said device is made from a stationary solid phase and a liquid phase containing the active ingredient in aqueous solution, the solid phase being formed from a solid with a fleecy or spongy structure.
摘要:
The invention relates to a transdermal therapeutic system, preferably a transdermal patch, having an active ingredient-containing matrix formed substantially of a water-insoluble base material, such as rubber and synthetic polymers, into which is incorporated water-soluble and/or water-swellable inclusion bodies, e.g. inclusion bodies formed from polyvinyl alcohol or polyethylene glycol, that further include micronized or nanoscale active ingredient particles.
摘要:
The invention relates to a transdermal therapeutic system made of the following layers: a carrier layer (T), an active ingredient layer (R), a membrane layer (M) and optionally an adhesive layer (K), wherein the carrier layer (T) is impenetrable to the active substance and to water, the active substance layer (R) comprises as an active substance component the salt of an alkali reactive active substance, such as a CNS-active amine in combination with at least one alkali reactive further component, and a polymer component (P1), wherein the active substance is released from the active substance layer (R) only by the moisture entering from the exterior through the membrane layer (M), and the membrane layer (M) is made of a polymer component (P2), allowing a uniform delivery of basic active substances to the skin.

Disclosed is a monitoring system for collecting and/or transdermally rediffusing air containing environmental contaminants. The inventive monitoring system generally includes at least one diffusion collector and/or an equilibrium diffuser. The diffusion collector is provided with at least three layers, i.e. an adhesive layer that is in direct contact with the skin of a living being, a barrier layer, and a collecting layer on the exterior face of the monitoring system. The equilibrium diffuser includes an adhesive layer and a collecting layer. The collecting layers and the adhesive layers of the two components of the monitoring system are preferably made of the same material and have the same dimensions.
摘要:
A device for the administration of basic active agents, such as nicotine, to the human or animal body. The active agents are administered by inhalation. The device comprises a first preparation containing a nicotine base or/and a further basic active agent and, a second or further preparations. At least one preparation contains at least one volatile acid suitable for inhalation.

摘要:
A composition for transdermal delivery, particularly iontophoretic transdermal delivery, having at least one cationic active agent or a salt thereof. The composition comprises at least one cationic active agent or a salt thereof, at least one polyamine and/or polyamine salt, water or an aqueous solvent mixture, and optionally one or more additives. Use of the composition as a component of a transdermal patch or of an iontophoretic transdermal patch is also provided, as well as the use of the composition in a method for transdermally or iontophoretically administering cationic active agents. A method for determining the in vitro skin permeation properties of an active agent-containing iontophoretic composition is also provided.
