摘要:
The invention relates to a transdermal therapeutic system, comprising a back layer that is impermeable to an active ingredient, a polymer matrix containing the active ingredient, and a protective layer that can be pulled off, wherein 5-aminolevulinic acid hydrochloride is used as the active ingredient and the basic polymer of the polymer matrix is an adhesive polyacrylate. Said transdermal therapeutic system is suitable for diagnosing and treating preliminary stages of skin cancer, such as actinic keratosis, and oncological skin diseases.
摘要:
The invention relates to a transdermal, therapeutic system in the form of a plaster which contains acetylsalicylic acid and/or salicylic acid. Said system has a backing layer, an active ingredient reservoir attached thereto, a membrane which controls the administration of the active ingredient in the absence of other control mechanisms, an adhesive device for fixing the system onto the skin and a protective layer which can be detached before application. The system is characterised in that it contains at least one component from the group of pyrrol derivatives and at least one component from the group of terpenes.
摘要:
A transdermal therapeutic system that contains acetylsalicylic acid as active substance has a laminated structure with a substantially active substance-and humidity-tight back layer, as well as one or several active substance-containing matrix layers. The transdermal therapeutic system is characterised in that at least one of the matrix layers contains acetylsalicylic acid mainly in the crystalline form.
摘要:
The invention relates to a pharmaceutical preparation containing lerisetron and provided in the form of a transdermal therapeutic system (TTS). The inventive preparation comprises a backing layer, an active substance reservoir and a detachable protective layer. Said active substance reservoir is adhesive, has at least one layer, contains lerisetron, is joined to said backing layer, and is based on silicon adhesive(s).

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. Said transdermal therapeutic system comprises 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:
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.
