27. A composition providing controlled release of one or more drug substances, the composition comprising:
-
a matrix comprising one or more drug substances and one or more polyglycols selected from polyethylene glycol and polyethylene oxides; and a coating that is substantially insoluble, non-erodible and non-permeable to water, said coating partly covering the matrix; wherein the composition is formulated such that the one or more drug substances are released from the composition by erosion of the matrix and said composition does not exhibit ethanol-induced dose dumping of the one or more active agents. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
