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.
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.
摘要:
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:
The invention relates to transdermal therapeutic systems (TTS) which include, as active ingredient, the NMDA receptor antagonist memantine or one of its physiologically compatible salts. The TTSs can be produced and used for treating diseases of the central nervous system.
摘要:
The invention relates to a transdermal therapeutic system for administering the active substance buprenorphine. Said system comprises at least one carboxylic acid that determines the solubility of buprenorphine in the matrix layer and that can likewise be absorbed. The transdermal therapeutic system according to the invention is used in the treatment of pain and is characterized by a considerably increased utilization of the active substance.
摘要:
The invention relates to a transdermal therapeutic system (TTS) which is suited for the administration of a peptide to a patient through skin treated with ablation. The transdermal therapeutic system incorporates a back layer and an active substance-containing layer that includes at least one peptide and a carrier substance.
摘要:
The invention relates to a transdermal therapeutic system (TTS), which is suited for the administration of a peptide to a patient through skin treated with ablation. The transdermal therapeutic system includes a back layer and an active substance-containing layer that contains at least one peptide and a carrier substance, preferably as a textile web material.
摘要:
A pharmaceutical preparation adhering to the skin, in particular a transdermal therapeutic system, for the release of the active substance 17-&bgr;-estradiol, contained therein in dissolved form being between its saturation concentration in equilibrium with a gas phase of less than 10% relative air humidity and its saturation concentration in equilibrium with a gas phase of more than 90% relative air humidity, in all matrix levels and, if present, also in an adhesive layer, characterized in that the estradiol quantity contained in in the preparation amounts to at least three times the saturation solubility measured at 95% relative air humidity, and that the air enclosed in the package is adjusted to a relative air humidity between 5% and below 0.5%.
