  • Patent number: 8641948
    Abstract: A process for preparing solid dispersions of highly crystalline compounds. The highly crystalline or thermally labile therapeutic compounds are processed in an extruder in combination with a solubilizing agent and optionally a plasticizer. The resulting extrudate features the therapeutic compound in an amorphous state. Particularly useful as the solubilizing agents are surfactants such as poloxamers.

  • Patent number: 8613949
    Abstract: The present invention relates to a pharmaceutical oral fixed dose combination comprising a) a therapeutically effective amount of Aliskiren, or a pharmaceutically acceptable salt thereof, b) a therapeutically effective amount of Amlodipine, or a pharmaceutically acceptable salt thereof, wherein the pharmaceutical oral fixed dose combination shows an in vitro dissolution of component (a) of 60% or less after 10 minutes and 98% or less after 20 minutes, and a dissolution profile of component (b) of 50% or more after 20 minutes, and 70% or more after 30 minutes at pH 2, said pharmaceutical oral fixed dose combination being bioequivalent, or close to reaching bioequivalence, to a free dose combination of Aliskiren and Amlodipine.

  • Publication number: 20120009257
    Abstract: The invention provides a pharmaceutical oral fixed dose combination of aliskiren and valsartan. Aliskiren is shown to slow the dissolution rate of valsartan and the resultant undesirable gelling of valsartan in the presence of aliskiren is overcome by the use of disintegrants.
