|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.|

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.
