For most materials, tablet dimensions change between the tablet being compressed and it being ejected. Occasionally, contraction of the tablet is observed but typically expansion occurs. This is termed elastic recovery. Excessive elastic recovery is associated with manufacturing defects, particularly capping. Such defects require the slowing of tablet presses which can have a massive impact on productivity. Checking for elastic recovery during development and manufacture can help identify materials or formulations at risk capping and other defects. We can minimise elastic recovery by selecting the right excipients.
