Extended-release pharmaceutical formulations |
abstract |
The present invention provides matrix-forming, sustained-release pharmaceutical formulations comprising four primary components: i) an effective amount of at least one drug substance; ii) at least one pharmaceutically acceptable, water-swellable, pH independent polymer; iii) at least one pharmaceutically-acceptable, anionic, pH dependent polymer; and (iv) a pharmaceutically-acceptable polymer selected from the group consisting of a) at least one pharmaceutically-acceptable cationic polymer; and b) at least one pharmaceutically acceptable hydrocolloid. The present formulations can be used with compounds having a wide range of solubilities as well as compounds characterized as having hydrophobic or hydrophilic characteristics. |
