Summary for Patent: 8,759,351

Title:	Methods for administering aripiprazole
Abstract:	The present invention relates, in part, to the discovery that a pharmaceutical composition comprising aripiprazole and a carrier administered in a bolus injection resulted in an extended release profile similar to that obtained by the injection of a poly lactide-co-glycolide microsphere formulation containing the active agent. This surprising result suggests that pharmacologically beneficial extended release formulations without the complexities and expense associated with the manufacture microspheres.
Inventor(s):	Brown; Josiah (Seattle, WA)
Assignee:	Otsuka Pharmaceutical Co., Ltd. (Tokyo, JP)
Application Number:	13/648,544
Patent Claims:	1. An injectable composition that is free of sustained release matrices for the extended release of aripiprazole comprising a suspension of at least about 10 mg/ml of aripiprazole in an injection vehicle optionally comprising a viscosity enhancing agent wherein the aripiprazole release is for at least 21 days. 2. A method for providing aripiprazole to an individual in an extended release injectable composition that is free of sustained release matrices comprising administering a mixture of at least about 10 mg/ml of aripiprazole in an injection vehicle optionally comprising a viscosity enhancing agent, wherein a therapeutically effective amount of the aripiprazole is present in the plasma of the individual for at least about 21 days.
