摘要:
A formulation comprising i) fenofibric acid, a physiologically acceptable salt or derivative thereof and optionally other active substances, ii) a binder component comprising at least one enteric binder, and optionally iii) other physiologically acceptable excipients is described. Fenofibric acid, the physiologically acceptable salt or derivative thereof is preferably in the form of a molecular dispersion in these formulations. An advantageous process for their preparation, in particular by melt extrusion, and the use of this formulation for oral administration of fenofibric acid, a physiologically acceptable salt or derivative thereof are likewise described.
摘要:
A solid pharmaceutical dosage form providing improved oral bioavailability is disclosed for inhibitors of HIV protease. In particular, the dosage form comprises a solid dispersion of at least one HIV protease inhibitor and at least one pharmaceutically acceptable water-soluble polymer and at least one pharmaceutically acceptable surfactant, said pharmaceutically acceptable water-soluble polymer having a Tg of at least about 50° C. Preferably, the pharmaceutically acceptable surfactant has an HLB value of from about 4 to about 10.
摘要:
Solid foamed active ingredient preparations based on melt-processable polymers, obtainable by extrusion of a melt of one or more polymers which comprises active ingredient and which is impregnated with a volatile, physiologically acceptable blowing agent and expanded.

Transparent rapid release active substance compositions obtainable by extrusion of melts, containing non-steroidal analgesics, homopolymers of N-vinylpyrrolidone, saccharides or sugar alcohols and sodium or potassium salts.
摘要:
A process for producing solid combination tablets which have at least two phases comprises molding a melt of a polymeric binder with or without at least one active ingredient, there being at least one solid product, which may contain an active ingredient incorporated into the still plastic composition during the molding step.
摘要:
A fluidized-bed process for preparing hydrogen peroxide, C.sub.1 -C.sub.4 -monopercarboxylic acids and C.sub.4 -C.sub.18 -dipercarboxylic acid complexes in which a solution of hydrogen peroxide, a C.sub.1 -C.sub.4 -monopercarboxylic acid, a C.sub.4 -C.sub.18 -dipercarboxylic acid or a mixture thereof in water or carboxylic acids is applied to a pulverulent or pregranulated matrix and fluidized-bed drying takes place.
摘要:
Iodophore containing a) 20-71% by weight of PVP or poly-N-vinylcaprolactam, b) 20-71% by weight of dextrin of DE 2-40, c) 6-25% by weight of elemental iodine, d) 3-12.5% by weight of iodide ions, and process for its preparation are disclosed.
摘要:
Disclosed is a method for producing dosing molds, according to which two separating films (7) are contacted with each other in a defined area, an active substance-containing melt is introduced between the separating films (7) such that a pocket for receiving a portion of the melt is embodied in at least one of the separating films, and the separating films (7) are separated from each other in order to eject the portion. Preferably, a method is disclosed in which the separating films (7) are contacted with each other in the gap of two molding rolls (2, 3) which rotate in opposite directions and are provided with opposite recesses (4, 5) on the surface thereof, and into which the separating films (7) can be pressed when the active substance-containing melt is introduced so as to form pockets. The separating films (7) make it possible to avoid a direct contact between the melt and the rolls (4,5) and thus prevent the melt from adhering to the roll (2, 3). Elastically deformable separating films (7) support the ejection process as a result of the stress thereof being released after leaving the roll gap (2, 3).
摘要:
The present invention relates to a process for the production of lenticular tablets by melt calendering in which molding rolls with depressions in the shape of segments of an ellipsoid are used. The process according to the invention affords tablets which are easily deflashed and in which the tablet residue to be abraded when there is a displacement between the upper and lower half of the tablet is small.
