Abstract: The present invention relates to the pharmaceutical compositions of a mixture of dextro- and levo-amphetamines complexed with ion exchange resin and precursor resins. More particularly the invention relates to Attention Deficit Hyperactivity Disorder (ADHD) effective agent dosage forms that both facilitate oral ingestion and provide an effective treatment over a prolonged period oftime. In particular, the invention provides for pharmaceutical compositions having a first and second plurality of particles, where the first plurality of particles comprises drug-resin particles and the second plurality of particles comprises drug-precursor resin particles with or without any extended release coating, where the drug is an ADHD effective agent and the composition achieves an escalating in vivo plasma concentration of the ADHD effective agents selected from amphetamine and methylphenidate.

Abstract: Provided are multilayer compressed oral dosage forms comprising naproxen or a pharmaceutically acceptable salt thereof and sumatriptan or a pharmaceutically acceptable salt thereof. Processes of making and using the oral dosage forms also are described.
