Disclosed herein is a oral extended release dosage form comprising a
plurality of granules of an effective amount of a pharmaceutically active
compound, at least one amino acid, and an intragranular polymer in which
the granule is dispersed within a hydrophilic extragranular polymer
matrix which is more rapidly hydrating than the intragranular polymer.
The amino acid is selected for hydropathy characteristics depending on
solubility characteristics of the active compound.
