Pharmaceutical Compositions

摘要

Provided herein is a pharmaceutical composition comprising an antagonist, an agonist, a seal coat, and a sequestering polymer, wherein the antagonist, agonist, seal coat and at least one sequestering polymer are all components of a single unit, and wherein the seal coat forms a layer physically separating the antagonist from the agonist from one another. Methods for manufacturing such a pharmaceutical composition are also provided.

主权项

1. A multi-layer pharmaceutical composition comprising an antagonist in a first layer and an agonist in a second layer upon said first layer such that the antagonist is substantially sequestered when administered to a human being in an intact form, such that physical disruption of the dosage form decreases the euphoric effect of the agonist when administered to a person as compared to an immediate release agonist composition.
