The extended-release tablet uses two release-rate controlling mechanisms: a primary polymer matrix core composed of drug with excipients and a secondary enteric coating surrounding the core. Upon swallowing, water is taken up through the enteric coating membrane into the primary core matrix, and the enteric coating membrane will dissolve at rising gastrointestinal pH value, which in turn slowly releases the drug from the formulation. Product meets USP dissolution test 15.
