The role of granulation in a changing pharmaceutical landscape

Jan 11 2019Dry granulation can be achieved in two ways slugging in which a large compact is formed and then broken down into granules using a mill or roller compaction when material is compressed into a ribbon prior to the production of granules Dry granulation is required when wet granulation may be unsuitable as a manufacturing method
