1. A composition comprising bupropion hydrobromide and at least one controlled release polymer that reduces the ratio of the maximum/minimum plasma bupropion hydrobromide concentration
(Cmax/Cmin) while maintaining bupropion plasma levels within the therapeutic window upon administration to a patient.
2. A composition comprising bupropion hydrobromide and and at least one controlled release polymer that controls the release of the bupropion hydrobromide upon administration to a patient to provide plasma concentrations of the bupropion hydrobromide within a therapeutic range over a 24 hour period.
3. A composition comprising bupropion hydrobromide and at least one controlled release polymer that releases the bupropion hydrobromide upon administration to a patient to provide a time delay between administration and the commencement of bupropion hydrobromide-release in the external environment of use.
