[The effect of dehydration loss of tablet excipients on the energy- distance diagram and on tablet characteristics].

Four tabletting agents of the micro-crystalline cellulose type (Heweten 10, Heweten 12, Heweten 40 and Avicel PH 101) as well as a potato starch lactose granulate had been tabletted on an instrumented slow-motion eccentric press (1 r. p. m.) following storage at different relative humidities. The data resulting from force-punch displacement measurements had been related to the radial steadiness to breakage and the dehydration loss of the relevant agent.
