Remission in Children and Adolescents Diagnosed with Attention-Deficit/Hyperactivity Disorder via an Effective and Tolerable Titration Scheme for Osmotic Release Oral System Methylphenidate

The purpose of this study was to identify the optimal dose of osmotic release oral system methylphenidate (OROS-MPH) using a dosage forced-titration scheme to achieve symptomatic remission in children with attention- deficit/hyperactivity disorder (ADHD). We also evaluated the efficacy and safety of, and patient and parent satisfaction with, the change in therapy from immediate-release methylphenidate (IR-MPH) to OROS-MPH over 10 weeks.

Method: We recruited 521 children and adolescents aged 6-18 years with an American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) diagnosis of ADHD, who had received IR-MPH treatments (<70 mg/day) for at least 1 month. The treatment, switched from IR-MPH to OROS-MPH according to a conversion scheme, started with a 6-week forced-titration phase of OROS-MPH to achieve symptomatic remission (defined as a score of 0 or 1 for each of the first 18 ADHD items in the Chinese version of the Swanson, Nolan, and Pelham, Version IV [SNAP-IV]), followed by a 4-week maintenance phase. The global ADHD severity and drug side effects of the participants were evaluated. Parents completed the ratings scales for the ADHD-related symptoms. Patient and parent satisfaction for the OROS-MPH treatment was also assessed.

Results: Among the 439 participants with ADHD who completed the trial, 290 participants (66.1%) achieved symptomatic remission. The mean dose of OROS-MPH among participants in remission was 36.7 mg (1.08 mg/kg) per day. Increased efficacy, superior satisfaction, and safety equivalent to that of IR-MPH were demonstrated in intra-individual comparisons from the baseline to the end of study. Determinants for remission included less severe ADHD symptoms (SNAP-IV score < 40), no family history of ADHD, and an appropriate dosage of medication according to the patient�s weight.

Conclusions: The findings suggest remission as a treatment goal for ADHD therapy by providing an optimal dosage of medication for children and adolescents with ADHD through using an effective and tolerable forced-titration scheme.
