Abstract: A dosage form for administration of two or more active pharmaceutical ingredients to a subject, comprising a first pharmaceutical composition comprising a first active pharmaceutical ingredient and optionally one or more pharmaceutically acceptable excipients in a first physical form selected from the group consisting of powder, granule, pellet, bead or mini-tablet form, and at least a second pharmaceutical composition comprising a second active pharmaceutical ingredient and optionally one or more pharmaceutically acceptable excipients in a second physical form selected from the group consisting of granule, pellet, bead, mini-tablet or tablet form, wherein the composition is characterized in that said first and second physical forms are selected to be different to minimize interactions between said first and second pharmaceutical compositions and to allow separation of said first and second pharmaceutical compositions for analysis on the basis of size difference.

Abstract: A multi-stage process to control the particle size of a pharmaceutical substance comprising the steps of: passing the pharmaceutical substance through a first stage of a particle size reduction process with a first set of particle size control parameters to obtain a feedstock of reduced median particle size and lesser distribution of median particle size for a second stage of a particle size reduction process; passing the feedstock, through a second stage of a particle size reduction process with a second set of particle size control parameters; optionally, using the product of the second stage or subsequent stages as a feedstock in further stages of a multi-stage particle size reduction process with a set of particle size control parameters for each stage; and collecting a pharmaceutical substance with a median particle size greater than 10 ?m and with a narrow, reproducible distribution of median particle sizes.

Abstract: A pharmaceutical formulation comprising desvenlafaxine having an MMD of between about 5 ?m and about 100 ?m, or a pharmaceutically acceptable salt thereof, and at least one matrix rate-controlling pharmaceutically acceptable polymer, solid unit dosage form containing it, methods for preparing such a formulation and for its use to treat depression and related disorders and diseases.
