摘要:
The invention relates to an oral multiparticle pharmaceutical dosage form in the form of a receptacle reducing the pH values of stomach, containing a plurality of pellets, particles, granules or agglomerates whose mean diameter ranges from 50 to 2500 μn substentially consisting of a) an internal matrix layer containing an active agent which is neither peptide or protein, nor the derivatives or conjugates thereof, a lipophilic matrix whose melting point is greater than 37° C. and a polymer with mucoadhesive effect, b) an external film coating substentially consisting of a polymer or an anionic copolymer which is optionally formulated with conventional pharmaceutical additives, wherein the active agent has a water solubility according to DAB 10, of at least 30 volume parts of water for one part by weight of the active agent and is coated with the lipophilic matrix and said active agent-containing lipophilic matrix is coated with a matrix made of a polymer with mucoadhesive effect. A method for producing the inventive multiparticle pharmaceutical dosage is also disclosed.

The present invention relates to a lyophilised nanoemulsion comprising a lipophilic phase and one or more sucrose fatty acid esters, to the nanoemulsion which can be prepared from the lyophilised nanoemulsion by redispersion, and to a process for the preparation of the lyophilised nanoemulsion.
摘要:
Pharmaceutical drug particles of small particle size are produced by combining a solvent-non-solvent precipitate with an in-situ spray drying process. A pharmaceutical drug is dispersed in a water-miscible solvent, in particular ethanol, and heated in an infeed line under pressure to above the boiling point of the solvent until the drug dissolves. This solution collides as a fine liquid jet with a fine water jet in a gas-permeated microreactor, and the fine mist so arising vaporises rapidly. The organic solvent vaporizes first, then the water. The water may contain surface modifiers.
摘要:
The present invention relates to a strategy for improving the permeability and solubility of pharmaceuticals, based on adding a chemically modified amino alkyl methacrylate copolymer E, wherein the chemical modification is the quaternization of a fraction of the existing amino alkyl groups.

The invention relates to a piece of furniture and to a device for influencing the movement of furniture parts which can be moved with respect to one another, having a guide unit for guidance of a first furniture part on a second furniture part, and having a drive unit by means of which the first furniture part can be moved, in a driven manner, relative to the second furniture part, with the guide unit having a fixed rail, which is associated with the second furniture part, and a moving rail, which is associated with the first furniture part. A pulling-pushing element is provided in order to apply a drive effect from the drive unit to the first furniture part, guided on the fixed rail via guide means.
摘要:
The Invention relates to a particulate system for use in diminishing cell growth, in particular the growth of cancer cells, comprising one or more water soluble lanthanide compounds that are embedded in a solid biodegradable polymer particle, the polymer being selected from the group consisting of polycarbonic acids, polylactic acids, polyglycolic acids, polypeptides or combinations thereof.

摘要:
In a conveying pump having a cylinder introducible into a reservoir and having a pump piston, whereby the conveyed medium is supplied via an ascending line to a discharge line, an ascending line formed of two sections adjustable relative to one another is provided. The ascending line can be locked at different heights to vary the length of the ascending line so that the conveying pump can be used for reservoirs of different heights without deteriorating the conveying capacity of the pump. This adaptation can be performed easily and quickly. In addition, the conveying pump can be taken apart and easily cleaned, and component parts can be easily replaced.
