Color-coded jigsaw design tablet compressed from therapeutic extruded cylindrical granules of visibly different colors
Abstract
Abstract THERAPEUTIC TABLETS OF IMPROVED UNIFORMITY OF COMPOSITION, ABSORBABILITY, SIZE AND APPEARANCE; INCREASED STRENGTH AND GREATER DENSITY, AS WELL AS ELEANT APPEARANCE; AND MULTICOLORED SURFACE AND CROSS-SECTION FOR COUNTERFEIT DETECTION AND A PRODUCT IDENTIFICATION ARE OBTAINED BY COMPRESSION INTO TABLETS OF A DRIED PLASTICIZED EXTRUDED MIXTURE. THE MEDICAMENT, A BINDER, AND A LIQUID, OFTEN WATER, ARE COMPACTED, HOMOGENIZED, AND EXTRUDED THROUGH A HIGH PRESSURE SCREW EXTRUDER AS SMALL STRANDS, WHICH ARE DRIED, AND BEFORE OR AFTER DRYING DEGMENTED INTO GRANULES, WITH THE DRING GIVING A SURFACE HARDNESS TO THE GRANULES. ON LUBRICATION AND COMPACTION, A DENSER MOR UNIFORM TABLET IS PRODUCED, WITH REDUCTION OR ELIMINATION OF CAPPING AND LAMINATING, AS COMPARED WITH CONVENTIONAL PROCEDURES.
