title: Preformulation studies in a drug development program for tablet formulations.
abstract: Recently developed techniques were applied in a preformulation program to select a compound and a suitable salt for use in a one-month toxicological test. The program showed that valuable information can be obtained prior to the choice of a compound as a candidate for a solid-dosage form. Information about the physical and mechanical properties of the chosen compound can be obtained with a limited amount of substance, i.e., surface color and hygroscopicity (1-2 g), dissolution rate and solubility (1-2 g), powder properties (1-2 g), and compaction properties (5-7 g).
