title: Modified release bi-layered tablet of melatonin using beta-cyclodextrin.
abstract: A modified release bi-layered tablet of melatonin incorporating a fast release fraction consisting of melatonin-beta-cyclodextrin inclusion complex and a slow release fraction containing melatonin in HPMC K15M and Carbopol 971 P matrices was prepared. The formulation developed showed an initial burst followed by a near zero order release pattern for a period of 8 h. The drug content, physical characteristics and the release profile were unaffected after 3 months of an accelerated stability study at 40 degrees C and 75% relative humidity.
