Abstract:
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.
Abstract:
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.
Abstract:
The invention relates to a transdermal therapeutic system (10) comprising a pharmaceutical active agent formulation (13), an adhesive layer (11) comprising a contact surface (12), and at least one ultrasound transmitter (21), the side of the ultrasound transmitter opposing the contact surface being directly or indirectly adjacent to the pharmaceutical active agent formulation. The transdermal therapeutic system is a multi-layered laminate, one of the laminate layers comprising the ultrasound transmitter, another comprising the adhesive layer, and another comprising the pharmaceutical active agent formulation. Furthermore, from a top view, at least in a plane position of the transdermal therapeutic system, all of the laminate layers (11, 21, 14) are at least approximately mutually congruent and are at least approximately the size of the contact surface. The inventive system provides an ultrasound-reinforced transdermal therapeutic system characterized by an extensive use of active agents, enabling an improved absorption of active agents through the skin.
Abstract:
The transdermal pharmaceutical preparations for the treatment of Parkinson's disease contain a combination of at least two active substances selected from the following groups of active substances: dopamine agonists and L-dopa, monoamine oxidase inhibitors, anticholinergics, NMDA-receptor antagonists, sympathomimetics; at least two of the said active substances being members of different active substance groups.
Abstract:
The invention relates to a transdermal therapeutic system (TTS) for administering pharmaceutical agents through the skin, comprising a back layer (R) impermeable to the agent and at least one layer (S) comprising the agent, wherein the layer (H) facing the skin comprises urea in solid form, allowing continuous administration of large quantities of agent over a long period of time.
Abstract:
A transdermal therapeutic system consisting of a backing layer, at least one active substance-containing matrix layer, which may at the same time possess pressure-sensitive adhesive properties, as well as a removable protective layer is characterized by a content of a neuroleptic, a content of at least one permeation enhancer as well as by a layer which is pressure-sensitive adhesive on the skin-facing side and based on polymers which are pure hydrocarbons.
Abstract:
Individually dosed active substance-containing and, in particular, aromatic-containing, film-shaped administration form, rapidly disintegrating upon contact with a liquid, wherein the aromatic is present as an internal, liposoluble phase in the form of liquid droplets distributed within an outer, solid but water-soluble phase, is characterized in that the said outer phase contains: at least 40% (w/w) polyvinyl alcohol 0 to 30% (w/w) of a surface-active substance, and that the constituent amount of the inner phase, relative to the outer phase, is between 0.1 and 30% (w/w), in each case relative to the water-free portions.
Abstract:
A process for introducing a plurality of segregated sheet-like administration forms into a dispenser under formation of a multilayered stack for individually dosable removal, with sheet-like tapes wound-up on rolls being present as starting material, utilizes the following steps. In a first step, a number of sheet-like layers of said tapes, which number corresponds to the stack, is simultaneously drawn from a plurality of rolls. In a further step, the individual tapes are united, using guide means, to form a multilayered strand, which in yet another step, is drawn forward to a cutting station where one length of stack is severed at a time, and wherein a length segment of the multilayered strand corresponding to the stack is substantially in the dispenser prior to being severed from a remainder of the multilayered strand by the cutting device.
Abstract:
The invention refers to a transdermal therapeutic system for the delivery of active agents to the human body.The backing layer consists of common pharmaceutical plastic layer laminates which require labeling, e.g. by printing. The problem to solve lies in toxicological, technological and drug law disadvantages of pigment- or varnish-printing.According to the invention, the coding does not consist of an ink- or pigment layer but in an effect on surface properties of the backing layer corresponding to the coding.
Abstract:
An active substance-containing adhesive patch with a pressure sensitive fixing device, containing at least one readily volatile ingredient, consisting of a substantially active substance-impermeable backing layer, at least two active substance-containing matrix layers and a removable protective layer, whereby the matrix layer containing the readily volatile active substance is laminated on a separately produced composite of one or more further matrix layers which are active substance-free, is characterized in that the first active substance-containing matrix layer consists of a spreadable molecularly disperse solution of the matrix base material in the readily volatile ingredient as the exclusive solvent, the composite which is obtained after laminating forming an active substance matrix that is as a whole shear-resistant after migration of the readily volatile ingredient into the composite.
