摘要:
A transdermal therapeutic system which is free of fibrous constituents, and a method for the production of such a transdermal therapeutic system A preparation containing active substance is applied by a printing method onto the pressure-sensitive adhesive layer of the transdermal therapeutic system.
摘要:
Process for the production, transport and storage of a therapeutic system which is in the form of a plaster and has an active layer supersaturated with active ingredient and containing the active ingredient in homogeneous dispersion or in solution, characterized in that it is carried out avoiding process parameters which favour or induce crystallization of active ingredient, and any type of pressure operating on the plaster and, in particular, on the active layer is avoided while it is carried out.
摘要:
A dermal or transdermal therapeutic system comprising a sheet-like substrate or reservoir containing readily volatile auxiliary agents or active agents, which substrate or reservoir is covered on one of its sides with a backing layer impermeable to the ingredients and on the opposite side with a detachable, likewise impermeable protective layer to prevent loss of ingredients during prolonged storage, is characterized in that both the backing layer and the protective layer are made of plastic film which is on both sides with vapour-deposited metal
摘要:
The invention relates to a dermal plaster for the transdermal provision of nitroglycerin comprising a carrier film and a removable protective film and an adhesive mass containing nitroglycerine on the basis of a cross-linked acrylate-vinyl acetate copolymer in which the monomer mix used for polymerization consists essentially of 21 to 40% wt. vinyl acetate, 55 to 70% wt. of an acrylic acid C2-8 alkyl ester and 3 to 10% wt. of an acrylic acid C2-4 hydroxyalkyl ester and which is cross-linked by heating and the removal of any solvents present after the addition of a cross-linking agent and the nitroglycerin.
摘要:
The invention relates to an apparatus for the controlled delivery or release of nitroglycerin to the human or animal skin, preferably in plaster form with a nitroglycerin-impermeable backing layer, a one or multiple-part reservoir containing a pressure sensitive adhesive nitroglycerin in uniform or irregular distribution and optionally a removable protective layer impermeable for nitroglycerin, the reservoir being produced using hol melt pressure sensitive adhesives with a processing temperature of 40.degree. to 80.degree. C., preferably 40.degree. to 60.degree. C. and in particularly preferred manner 40.degree. to 45.degree. C., a process for the production thereof and the use of the apparatus for therapeutic purposes in human and veterinary medicine.
摘要:
A transdermal therapeutic system in plaster form for controlled release of oestradiol in combination with norethisterone acetate, comprising a backing layer, a reservoir supersaturated with active ingredients which is attached to said backing layer and prepared using polyacrylate pressure-sensitive adhesives and crystallization inhibitors, and a detachable protective layer, is characterized in that the crystallization inhibitor is an amino-containing polymer.
摘要:
An active substance-containing patch for the controlled release of estradiol or its pharmaceutically acceptable derivatives alone or combined with gestagens, comprising a backing layer, an active substance-containing reservoir which is bonded thereto and produced by using pressure-sensitive adhesives, and a removable protective layer, is characterized by the fact that the pressure-sensitive adhesive comprises ethylcellulose, esters of non-hydrogenated and/or hydrogenated colophony, and lauric acid.
摘要:
An active substance-containing patch for the controlled release of nitroglycerin to the skin, consisting of an impermeable backing layer, a reservoir attached thereto and comprising pressure-sensitive hot melt adhesive and active substance, and a removable protective layer, in which patch the reservoir comprises in homogeneous mixture: a) tackifying soft and/or hard resins, b) plasticizers, c) nitroglycerin preparation.
摘要:
An active substance-containing patch for controlled release of estradiol or its pharmaceutically acceptable derivatives, alone or in combination with gestagens, to the human or animal skin, consisting of a backing layer, an active substance-containing reservoir connected thereto which is suitable for combined active substance release and which has been produced using pressure-sensitive adhesives, and a detachable protective layer, is characterized in that the pressure-sensitive adhesive contains wool wax or components thereof and zinc oxide.
摘要:
The present invention relates to active substance plasters for the controlled release of active substances to the skin consisting of a backing layer, an adhesive film connected therewith which film is water-soluble and consists of pressure-sensitive adhesive which comprises water-swellable polymers and in which the active substance is at least partially soluble, and of a removable protective layer covering the adhesive film, in which plasters the pressure-sensitive adhesive is based on homo and/or copolymers with at least one derivative of the acrylic or methacrylic acid, and which comprise as active substances, partially or completely dissolved in the adhesive, at a concentration of 0.5 to 10.0%-wt estrogens and their pharmaceutically acceptable derivatives alone or in combination with gestagens.
