1. An extended release pharmaceutical composition comprising tolterodine and an extended release polymer(s), wherein the composition comprises:
a) i) a drug layer comprising tolterodine tartrate and monosaccharide and/or disaccharide on an inert core wherein the drug layer is substantially free of the extended release polymer; or
ii) a drug core comprising tolterodine tartrate and monosaccharide and/or disaccharide wherein the drug core is substantially free of the extended release polymer; and b) a polymer layer comprising extended release polymer(s). |
