Abstract
Systems, methods and apparatuses for manufacturing dosage forms, and to dosage forms made using such systems, methods and apparatuses are provided. Novel compression, thermal cycle molding, and thermal setting molding modules are disclosed. One or more of such modules may be linked, preferably via novel transfer device, into an overall system for making dosage forms.
Claims12
A method of coating a dosage form comprising a first medicant, comprising the steps of:
- a) enclosing at least a portion of said dosage form in a mold cavity;
- a1) heating a flowable material to 80° C., wherein said flowable material comprises PEG and polyethylene oxide;
- b) providing said heated flowable material into said mold cavity so as to coat at least a portion of said dosage form with said heated flowable material, wherein said mold cavity is heated to 80° C. during the providing;
- b1) after the mold cavity is filled with said flowable material, decreasing the temperature of the mold cavity to below a melting or gel point of said flowable material to cool said flowable material;
- c) wherein said cooled flowable material forms a coating over at least a portion of said dosage form.
A method of coating a dosage form comprising a first medicant with first and second flowable materials, wherein said first and second flowable materials each comprise gelatin, comprising the steps of:
- a) enclosing a first portion of said dosage form in a first mold cavity;
- a1) heating said first flowable material to 55° C.;
- b) injecting said heated first flowable material into said first mold cavity so as to coat said first portion with said heated first flowable material, wherein said first mold cavity is heated to 55° C. during the injecting;
- b1) after the first mold cavity is filled with said first flowable material, decreasing the temperature of the first mold cavity to room temperature to cool said first flowable material;
- c) wherein said cooled first flowable material hardens to form a coating over said first portion;
- d) enclosing a second portion of said dosage form in a second mold cavity;
- d1) heating said second flowable material to 55° C.;
- e) injecting said heated second flowable material into said second mold cavity so as to coat said second portion with said heated second flowable material, wherein said second mold cavity is heated to 55° C. during the injecting;
- and
- e1) after the second mold cavity is filled with said second flowable material, decreasing the temperature of the second mold cavity to room temperature to cool said second flowable material;
- f) wherein said cooled second flowable material hardens to form a coating over said second portion.
