This study aimed to develop novel co-processed tablet fillers based on the principle of particle engineering for direct compaction and to compare the characteristics of co-processed products obtained by fluid-bed coating and co-spray drying, respectively. Water-soluble mannitol and water-insoluble calcium carbonate were selected as representative fillers for this study. Hydroxypropyl methylcellulose (HPMC), serving as a surface property modifier, was distributed on the surface of primary filler...
IPEC-Americas and IPEC Europe have jointly published a guide for excipient makers and users on co-processed excipients. This guide offers best practice and voluntary guidance on the development, manufacture and use of co-processed excipients and provides support to both manufacturers and users of co-processed excipients.
