Abstract
The present invention relates to an oral sustained-release triple layer tablet, more particularly, a triple layer tablet consisting of an inner immediate-release layer containing a pharmaceutically active ingredient and two outer layers containing swellable polymers. Upon exposure to aqueous media, the two outer layers swell to form gelled layers surrounding the lateral side of the inner layer rapidly, thereby control effectively the release of the pharmaceutically active ingredient from the inner immediate-release layer.
