Patent application numberDescriptionPublished
20080287885Cylinder/Piston Unit Having a Non-Cylindrical Chamber - The invention relates to a cylinder/piston unit having a cylinder and a piston which is guided therein, wherein the cylinder and the piston enclose a chamber which can be filled at least for a time with an additive, and the cylinder has at least one exit element at its front end. Here, the cross section of the chamber or the cross section of the cylinder inner wall is increased at least in regions of the cylinder from the front to the back, wherein the cylinder end having the exit element is at the front. The piston has an elastic skirt at least in the front region, the front outer edge of said elastic skirt defining a cross-sectional area in the case of an unloaded piston, which is greater than an area which is defined by a contour line. The present invention develops a cylinder/piston unit which ensures simple and reliable handling and can be stored for a long time in the filled state, in a manner which is impervious to gas and moisture.11-20-2008
20090143466Isolation of Atraric Acid, Synthesis of Atraric Acid Derivatives, and Use of Atraric Acid and the Derivatives Thereof for the Treatment of Benign Prostatic Hyperplasia, Prostate Carcinoma and Spinobulbar Muscular Atrophy - A method for isolating atraric acid from biological material, atraric acid derivatives, the chemical synthesis thereof, and the use of atraric acid and the derivatives thereof for treating or producing a medicament for treating benign prostate hyperplasia, prostate carcinoma or spinobulbar muscular atrophy is provided. In addition, a basic substance for the development of other agents used for treating benign prostate hyperplasia, prostate carcinoma, or spinobulbar muscular atrophy is provided.06-04-2009
20090159553Closure system for containers - A closure system for containers used for storing or administering substances in the form of liquids, pastes or powders, which system in one embodiment includes a cap, provided with a through-hole, and a closure element, wherein the cap holds the closure element with a force fit and/or form fit on the container, in the area of the container opening that is to be closed, by means of a catch element present on the container. For this purpose, the end face which surrounds the container opening, and on which the closure element bears, comprises a depression. The closure element is a virus-proof, bacteria-proof and spore-proof film that lies on the end face and, at least in some areas, over the depression. The cap is then fitted in place, an elastomer ring or adhesive ring is arranged between the closure element and the depression and fills the depression. With the present invention, a closure system for containers is provided that allows the container to be securely closed permanently and in a virus-proof, bacteria-proof and spore-proof manner.06-25-2009
20090166978Cylinder/piston unit with at least three sealing elements - A cylinder/piston unit is disclosed for pre-fill, storage and release when desired of an active substance, such as a medicament. The cylinder/piston unit is provided with a cylinder and with a piston which is guided therein and which is sealed off in a sterile manner by a rubber seal, the cylinder and the piston enclosing a chamber that can be filled at least temporarily with active substance, and the cylinder having at least one discharge element at its front end. For this purpose, the piston resting in a rear position is sealed off relative to the cylinder in a sterile manner by a static front sealing element and by a static rear sealing element. Arranged spatially behind each static sealing element, there is a parking area for receiving the respective sealing element. When the piston is actuated, the individual static sealing elements are transferred from their respective sealing position into a parked position located in the parking area, and each sealing element in the parked position touches only the cylinder wall or only the piston wall. With the present invention, a cylinder/piston unit is developed which can be pre-filled and in which, despite a sterile sealing of the piston, only a slight force has to be applied in order to accelerate and/or move the piston.07-02-2009
20090202597Ache-Nmda Combination Wafer - Sheet-like pharmaceutical preparations based on hydrophilic polymers, which rapidly disintegrate upon contact with moisture and which are used to treat dementia-related illnesses The dosage form contains an active agent combination of at least two active agents which are suitable for the treatment of dementia (antidementia agents). The antidementia agents should be chosen from the group comprising acetyl cholinesterase inhibitors (AChE inhibitors) and NMDA antagonists (n-methyl-D-asparaginic acid antagonists). The use of such an active agent combination for producing an orally administrable pharmaceutical product for the treatment of dementia-related illnesses such as Alzheimer's disease, as well as a procedure for the symptomatic treatment of Alzheimer's disease by the oral administration of one of the above pharmaceutical products is also provided.08-13-2009
20090203670Combination Antidepressants Wafer - A sheet-like pharmaceutical preparation (dosage form) that quickly disintegrates on contact with moisture, based on hydrophilic polymers for the release of at least one active agent. The dosage form contains an active agent combination for treating depression, and at least one active agent selected from the antidepressant group of drugs. In addition, the use of such a combination of active agents for the production of an orally administrable pharmaceutical product for the treatment of depression, and the therapeutic treatment of depression by oral administration of one of the named pharmaceutical preparations, is provided.08-13-2009
20090254036Single-use injector with at least one draw hook - A single-use injector is disclosed comprising a housing (10-08-2009
20090274732Type-2 Diabetes Combination Wafer - Rapidly disintegrating oral dosage forms for the application of active agent combinations for diabetes therapy. The dosage forms contain at least two active agents suitable for treating type-2 diabetes. The antidiabetic active agents are selected from the group comprising sulfonylureas, glitazones, glinides, biguanides, and absorption-delaying agents. The use of the active agent combination to produce an oral dosage form for the treatment of diabetes, a method for the therapeutic treatment of diabetes, and a method for the production of a sheet-like dosage form are also disclosed.11-05-2009
20090291123Opioid Combination Wafer - Sheet-like dosage forms for pain therapy, based on hydrophilic polymers, which rapidly dissolve or disintegrate in an aqueous environment and which release active agent combinations when placed into a body orifice or body cavity, and which are preferably orally administrable, with the dosage form containing an active agent combination consisting of an opioid and a second substance The second active agent is a non-steroidal anti-rheumatic (NSAR) or an antidepressant.11-26-2009
