Effect of particle size on the compaction mechanism and
The effect of particle size variation on tablet tensile strength for spray‐dried lactose Sta‐Rx 1500 and Avicel PH‐101 was investigated. Decreasing the particle size of spray‐dried lactose and Sta‐Rx 1500 resulted in stronger compacts whereas the tablet tensile strength of Avicel PH‐101 was unaffected by particle size variation.
