selection, poor powder flow, poor tableting, lack of hardness, high friability, elevated
disintegration time, low dissolution rate etc. Most of them are significantly influenced by the
mechanical properties (like elasticity, plasticity, brittleness, powder compressibility, tensile
strength, etc.) of the active pharmaceutical ingredient (API). Assessment of these properties
of the pure actives is not always easy. Absence of lubrication may induce a lot of friction …
