Abstract:
Pharmaceutical compositions of methylphenidate complexed with ion-exchange resin particles to form drug-resin particles are provided. The compositions have a first plurality of drug-resin particles that are uncoated and a second plurality of drug-resin particles that are coated with a delayed release coating. Preferably, the second plurality of drug-resin particles are coated with a triggered-release coating triggered by a pH change and a diffusion barrier coating.
