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.
