Abstract:
The invention relates to an aqueous pharmaceutical composition containing tapentadol or a physiologically acceptable salt thereof and being adapted for oral administration. The composition has excellent storage stability without relying on the presence of high amounts of preservatives.
Abstract:
The present invention provides a pharmaceutical dosage formulation, and more particularly, to a pharmaceutical dosage formulation comprising an HIV protease inhibitor.
Abstract:
The invention relates to a method for producing solid forms of administration by means of melt extrusion. A polymer binder, at least one pharmaceutical active agent and optionally, other additives are mixed and the mixture is melted in an extruder and then extruded in the form of a continuous plastic product strand. The inventive method is characterised in that the extruder used is a planetary roller extruder (10) which preferably has one central spindle (13) and six planetary spindles (14).

Abstract:
A method for producing solvent-free non-crystalline biologically active substances from corresponding crystalline biologically active substances in an extruder, characterised in that said substances are melted in an extruder in a vacuum without the presence of adjuvants and are cooled and ground.
Abstract:
Operation of a combined gas turbine/steam turbine process. The boosted primary high-pressure gas turbine process is operated by means of compressed air and a combustible fluid and the steam turbine process is operated with a fluidized bed combustor fed with a carbonaceous solid fuel. The combustion in the fluidized bed combustor is carried out with the oxygen-laden waste gases from the primary high-pressure gas turbine process and electrical energy can be produced by both turbine processes. To increase the efficiency, the pressure of the exhaust gases from the primary high-pressure gas turbine process (13) is reduced only until the fluidized bed combustor can be operated as a pressurized fluidized bed (6) and the pressure of the exhaust gases of the pressurized fluidized bed combustor is reduced after dust removal (14) in a second gas turbine process (2). These exhaust gases undergo heat exchange (10) with the compressed air of the primary high-pressure gas turbine process (13). The air for the primary high-pressure gas turbine process undergoes a two-stage compression (19) with recooling (8). The compression energy for the first stage (1) is derived from the second gas turbine process (2) and the energy for the second stage (9) from the primary high-pressure gas turbine process (13).
Abstract:
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.
