Abstract
The invention is directed to novel crystalline forms of lamotrigine. These novel crystalline forms of lamotrigine have improved dissolution and in-vivo absorption profile, as compared to pure lamotrigine. These novel crystalline forms of lamotrigine provide a substantial increase in the blood concentration of lamotrigine, as compared to pure lamotrigine when administered to a subject. These novel crystalline forms of lamotrigine also provide a slower, steady build up of lamotrigine blood concentration suitable for sustained release of lamotrigine in-vivo, as compared to pure lamotrigine.
