NCT00302354

Brief Summary

This is a double-blind, placebo-controlled study, three-period crossover study to examine the likeability of a single dose of OROS MPH (CONCERTAÒ 90mg) and a single dose of Long-acting MPH (RITALIN LAÒ 90mg). Hypotheses are as follows: Hypothesis 1: OROS-MPH (CONCERTAÒ) will be later than SODOS-MPH (RITALIN LAÒ) in its Tmax (time to Cmax). Hypothesis 2: The subjective feelings of detection and likeability would be greater for SODOS-MPH (RITALIN LAÒ) than for an equivalent total dose of OROS-MPH (CONCERTAÒ).

Medically acceptable forms of birth control include abstinence, hormonal contraceptives, diaphragm with spermicide, condom with spermicide, intrauterine device, or surgical sterilization (including vasectomy of male partner(s).
  • Eighteen (18) to 45 years of age, inclusive.
  • Based on medical history, physical examination, and/or lab results, are considered healthy and free of any conditions that may interfere with participation in the study. Any abnormalities at screening on results of ECG or any laboratory test must be determined to be not clinically significant by the investigator.
  • Agree to not use prescription stimulants (except for the study medication) during the study.
  • Have venous access sufficient for blood sampling as determined by clinical examination.
  • Weigh at least 110 pounds at screening.
  • Agree and are available to return to the study center for three full-day (approximately 14 hours) study visits held five to 30 days apart within a 10-week period, and willing to complete all protocol-specified assessments.
  • Able to read and comprehend English

You may not qualify if:

  • Known hypersensitivity to methylphenidate or components of CONCERTA or RITALIN, or to the sympathomimetic amines.
  • Presence or history of any medically diagnosed, clinically significant Axis I psychiatric disorder (including substance use disorders, bipolar disorder, any psychotic disorder, Tourette's disorder or family history of Tourette's)
  • Any clinically significant chronic disease or unstable medical abnormality by history or physical examination, including hypertension, glaucoma, hyperthyroidism, a seizure disorder, history of myocardial infarction or stroke, or history of cardiac arrhythmia or heart murmur (other than uncomplicated mitral valve prolapse).
  • Clinically significant abnormal baseline laboratory values which include the following:
  • Values \> 20% above the upper range of the laboratory standard of a basic metabolic screen.
  • Currently taking a monoamine oxidase inhibitor or have taken a monoamine oxidase inhibitor in the 14 days before initiation of study medication.
  • Currently taking or require any of the following medications: clonidine or other alpha-2 adrenergic receptor agonists, tricyclic antidepressants, selective serotonin reuptake inhibitors (SSRIs), theophylline, coumarin anticoagulants, anticonvulsants, or prescription stimulants.
  • Have taken an SSRI in the 35 days before initiation of the study medication.
  • Currently physically dependent on benzodiazepines, opiates or alcohol as determined by clinical evaluation or positive urine drug screen at screening.
  • Preexisting severe gastrointestinal narrowing (pathologic or iatrogenic, for example: small bowel inflammatory disease, "short gut" syndrome due to adhesions or decreased transit time, past history of peritonitis, cystic fibrosis, chronic intestinal pseudoabsorption, or Meckel's diverticulum).
  • Unable to swallow the study medication whole.
  • Have had a significant blood loss (\>500 mL) or donated blood in the 30 days preceding dosing.
  • Have a positive urine drug screen at screening.
