Dosage forms for oral administration of a methylphenidate drug are
provided. The dosage forms provide a substantially immediate dose of
methylphenidate upon ingestion, followed by one or more additional doses
at predetermined times. By providing such a drug release profile, the
dosage forms eliminate the need for a patient to carry an additional dose
for ingestion during the day. The dosage forms and methods provided are
useful in administering methylphenidate and pharmaceutically acceptable
salts thereof, which generally require one or more doses throughout the
day.
