Roller compaction Pharma Excipients

Roller compaction is the main technique employed in dry granulation. Ribbon sticking and splitting are among the major factors that can hinder the use of this process for some formulations. Ribbon splitting can occur either transversally (through the ribbon thickness) or longitudinally (through the ribbon width).

However stability studies indicated highest loss of enzyme activity with carrageenan tragacanth and

Roller Compaction Design and Critical Parameters in Drug

Roller compaction is a dry granulation technology in which powder is densified between two counter rotating rolls by the application of mechanical pressure as powder passes through the rolls. Dry granulation process powders consist of the active pharmaceutical ingredient and excipients e.g. diluents disintegrants and lubricants are mixed in suitable blender. The powder mixtures are then

Manufacturing Process Considerations for Fixed-Dose

Apr 01 2010 · On the other hand in mixtures with high microcrystalline cellulose RRS was low thus limiting the shearing solicitations after the release of pressure and before ejection. Thus the composition of combinations of binary mixtures can also be studied in a similar fashion to minimize stresses like RRS for optimization of compaction behavior.
