Tests evaluated commercial rotary tablet presses to see how effectively they deal with problems such as poor flow, overlubrication, and capping.

The tabletting properties of a new coprocessed excipient for direct compression were compared with a physical mixture of its components (separately and with drugs) and the individual constituents. The compaction properties were also investigated. Results indicated that the new excipient has excellent flow properties and demonstrates enhanced compressibility.
