  • Publication number: 20220409543
    Abstract: The present invention provides a method for preparing a pharmaceutical composition of a pharmaceutical ingredient (API) which is loaded on a carrier and stabilized therethrough. In particular, the present invention relates to a composition of a poorly soluble nanoparticulated API on a carrier in the dry state and which is processed as pharmaceutical formulation of said API with improved release profile and bioavailability.

  • Patent number: 11510986
    Abstract: The present invention relates to the use of spray-dried sorbitol, such as Parteck® SI, as plasticizer for polymer containing compositions processed by (hot) melt extrusion. Due to its improved properties, achieved by its special manufacturing process (spray drying), this direct compressible excipient shows more additional benefits than the same substance in crystalline state.

  • Publication number: 20220105041
    Abstract: For manufacturing a solid administration form comprising at least one active pharmaceutical ingredient, a flowable but setting composite material comprising the at least one active pharmaceutical ingredient is added together and set to generate the solid administration form. The flowable composite material is liquefied and delivered to a discharge unit. Small portions of liquefied composite material are intermittently discharged through an outlet into a setting unit. The flowable composite material comprises a polymer and at least one active pharmaceutical ingredient dispersed or dissolved within the polymer. The small portions are droplets and the solid administration form is generated by adding droplets that stick together before or during the setting of the liquefied composite material. An average diameter of the droplets can be less than 350 ?m. There can be a void space between at least some small portions, resulting in a porous structure of the solid administration form.
