A solid dose composition containing a mixture of a cured, modified release-barrier coated methylphenidate-ion exchange resin complex-matrix and an uncoated methylphenidate-ion exchange resin complex is described. The barrier coated methylphenidate-ion exchange resin complex-matrix comprises methylphenidate complexed with a pharmaceutically acceptable ion-exchange resin to form the complex which is admixed with a polymer to form a methylphenidate-ion exchange resin complex-matrix, which is subsequently coated with a modified release coating. The modified coating contains polyvinyl acetate polymer and a plasticizer and is cured.
