Abstract: The present invention provides compositions and methods for a modified-release pharmaceutical drug composition having a first charged active agent and a second charged active agent at least partially surrounded by a rate controlling membrane. The first charged active agent and the second charged active agent interact to form a modified release pharmaceutical complex within the rate controlling membrane and the modified release pharmaceutical complex has a release characteristic different from the release characteristic of the first active agent or the second active agent alone.

Abstract: The present invention provides a method and composition for loading one or more drugs in a solution onto one or more ion exchange resin particles to form a drug-loaded resin particle. The drug-loaded resin particle is separated from the solution and dried before recombining the drug-loaded resin particle with the solution to load more drugs onto the drug-loaded resin particle from the solution.

Abstract: The present invention provides a method and composition are provided for loading one or more drugs in a solution onto one or more ion exchange resin particles to form a drug-loaded resin particle. The drug-loaded resin particle is a sustained-release coated layered pharmaceutical drug-ion exchange resin having a one or more pharmaceutically active drugs applied directly to a non-equilibrated ion exchange resin to form a drug-resin complex. The drug-resin complex then coated is shelf stable.

Abstract: The present invention provides a method and composition are provided that includes an ion exchange resin treated with from between about 0.01 to about 10 percent by weight of one or more sugar alcohols in contact with one or more ionic pharmaceutically active drug.
