| abstract |
The present invention relates to a modified release composition of at least one form of venlafaxine, which is an enhanced absorption delayed controlled release composition for oral administration suitable for once daily dosing. The composition comprises a core comprising at least one form of venlafaxine selected from the group consisting of venlafaxine, an active metabolite of venlafaxine, a pharmaceutically acceptable salt of venlafaxine, a pharmaceutically acceptable salt of an active metabolite of venlafaxine, and combinations thereof, and a pharmaceutically acceptable excipient. The composition further comprises a modified release coating which substantially surrounds the core. The compositions of the invention provide enhanced absorption delayed controlled release of the at least one form of venlafaxine such that the combined geometric mean ratio of the composition of the invention to the reference product for the AUC 0-t or the C max for venlafaxine and its active metabolite O-desmethylvenlafaxine is greater than 2 after first administration of the composition under fed or fasting conditions. |
