Duragran allows for more uniformity and precise control of targeted particle sizes while providing production time and cost savings

The Duragran patented process eliminates the need for extrusion and spheronization for high API-loaded drug particulates by using our fluid bed processing technology that combines the particle sizing and coating processes to create controlled-release beads/granules of uniform and narrow particle size range or the need to layer product onto a uniform sized sugar bead.

Duragran allows us to create controlled release beadlets/granules of uniform and narrow particle size range without the use of spheronization/extrusion equipment or the need to layer product onto a uniform sized sugar bead.

Duragran for more uniformity and targeted sizing

Duragran™ creates granules of more uniform particle size with easily modified process parameters that can be used to target a desired particle size that standard wet granulation processes cannot attain. The technology can be applied to controlled-release formulations and to create taste-masked, orally disintegrating tablet formulations.


Duragran provides many benefits by reducing:

  • Overall production costs
  • Energy requirements
  • Quality Unit in-process monitoring
