Abstract

The invention provides an extended release pharmaceutical tablet containing:
(i) a core comprising by weight, based on the core weight, about 70% to about 99% metformin and pharmaceutically acceptable excipients; and (ii) a coating permeable to metformin. The extended release tablet of the invention exhibit a dissolution profile such that after about 2 hours, from about 7% to about 60%
of the metformin is released; after about 4 hours, from about 15% to about 90%
of the metformin is released; after about 8 hours, from about 50% to about 100% of the metformin is released; after about 12 hours, more than about 75%
of the metformin is released.
