Abstract
Controlled-release therapeutic compositions including melatonin combined with sedative and/or analgesic ingredients are described. The compositions have a solid core including melatonin in an acidified polymeric matrix. A sedative ingredient such as GABA receptor agonist may also be in the acidified polymeric matrix. The composition may include an expedited release portion providing a burst release of active ingredients and a sustained release portion providing a sustained release of active ingredients.
