Tabletability Modulation Through Surface Engineering

Poor powder tabletability is a common problem that challenges the successful development of high-quality tablet products. Using noncompressible microcrystalline cellulose beads, we demonstrate that surface coating is an effective strategy for modulating tabletability, almost at will, through judicious selection of coating material. This strategy has broad applicability as tabletability of such particles is dictated by the properties of the outermost layer coat regardless the nature of the core. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 104:2645-2648, 2015
