Patent ID: 8343546

Claim:
A method of preparing an ion exchange resin drug complex comprising the steps of: contacting one or more ion exchange resin particles with one or more pharmaceutically active drugs, adding about 0.01% to about 10% by weight of one or more sugar alcohols to the one or more ion exchange resin particles and one or more pharmaceutically active drugs, wherein the about 0.01% to about 10% by weight of one or more sugar alcohols is based on the combined weight of the one or more sugar alcohols, one or more pharmaceutically active drugs and the one or more ion exchange resin particles, and wherein the one or more sugar alcohols are distributed throughout the ion exchange resin particles, and coating the ion exchange resin particles with a water-permeable diffusion barrier and wherein the weight of sugar alcohol in the coated particles is about 0.01% to about 10% of the combined weight of the one or more sugar alcohols, one or more pharmaceutically active drugs and the one or more ion exchange resin particles.
