Method of producing solid shape forms containing an active ingredient
View Patent ↗The present invention relates to an apparatus for producing solid active ingredient-containing forms from an active ingredient-containing formulation which comprises at least one polymeric binder. The apparatus according to the invention has at least one extruder 1 for continuous plastication of the formulation and at least two injection units 2 which are provided separate from one another, each of which is connected to the extruder 1 , and through which the formulation can be injected into at least one mold 3 . In the process according to the invention for producing solid active ingredient-containing forms from an active ingredient-containing formulation which comprises at least one binder, the active ingredient-containing formulation is continuously plasticated, the plasticated formulation is fed into an injection unit 2 1 , and the formulation present in this injection unit 2 1 is injected into a mold 3 , and plasticated formulation is fed into another injection molding unit 2 2 , and the formulation present in the other injection molding unit 2 2 is injected into the mold 3 or another mold.
1. A process for producing solid active ingredient-containing forms from an active ingredient-containing formulation which comprises at least one polymeric binder, in which
the active ingredient-containing formulation is continuously plasticated,
the plasticated formulation is temporarily stored and then
the plasticated formulation is fed into an injection unit ( 2 1 ), the formulation present in this injection ( 2 1 ) is injected into a mold ( 3 ) and, during this, plasticated formulation is fed into another injection unit ( 2 2 ), and the formulation present in the other injection unit ( 2 2 ) is injected into the mold ( 3 ) or another mold
the temperature of the plasticated formulation is controlled by a hot runner system comprising injection runners, wherein the hot runner system has a fluid or an electrical heating with counter-cooling for controlling the temperature of the injection runners ( 6 ).
2. A process as claimed in claim 1 , wherein the volume of formulation fed into one injection unit ( 2 ) corresponds to the volume injected into the mold ( 3 ).
3. A process as claimed in claim 1 , wherein two sheets are placed in the mold ( 3 ) before the injection, between which the formulation is injected.
4. The process of claim 1 wherein the solid active ingredients are pharmaceuticals.
