  • Patent number: 10632113
    Abstract: Disclosed are solid oral pharmaceutical compositions that that are intended to provide protection against overdose and tampering, as well as abuse deterrence. The compositions contain a plurality of granules or multi-particulates. A first population of multi particulates contains an API or drug susceptible to abuse, a polymer matrix, and an outer coating that contains a cationic pH dependent polymer. These multi particulates also contain a plasticizer and a surfactant. A second population of multi particulates contains a viscosity building polymer and an alkaline buffering agent. Compositions may further include a disintegrant, and/or additional viscosity building polymers and/or alkaline buffering agents and/or ion exchange polymers. Also disclosed are the methods of making and using the compositions.
