Trial Summary
What is the purpose of this trial?This trial studies how methylphenidate affects brain activity and chemicals in adults with ADHD using brain scans. The goal is to develop better treatments for ADHD. Methylphenidate is the most common treatment for attention deficit hyperactivity disorder (ADHD) and has been shown to improve attention and behaviour.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What evidence supports the effectiveness of the drug Methylphenidate for treating ADHD?
Research shows that controlled-delivery methylphenidate, like Metadate CD, is effective in reducing ADHD symptoms in children and adolescents, performing better than a placebo and similarly to immediate-release versions. Additionally, dexmethylphenidate, a form of methylphenidate, has been found effective at managing ADHD symptoms at lower doses.
12345Is methylphenidate generally safe for humans?
Methylphenidate, used in various forms like Ritalin and Concerta, is generally well tolerated in treating ADHD in children and adults. Most reported side effects are mild and resolve quickly, but long-term effects are still being studied.
16789How is the drug Methylphenidate unique in treating ADHD?
Methylphenidate, especially in its controlled-delivery form (like Metadate CD), is unique because it provides effective symptom control throughout the school day with just one dose, making it convenient for children and adolescents with ADHD. It is also well-tolerated and can be used alongside behavioral and psychosocial interventions.

Methylphenidate controlled-delivery capsules (EquasymXL, Metadate CD): a review of its use in the treatment of children and adolescents with attention-deficit hyperactivity disorder. [2018]Controlled-delivery methylphenidate (methylphenidate CD) [EquasymXL, Metadate CD], an oral stimulant, is approved in the US and EU to treat children aged>or=6 years who have been diagnosed with attention-deficit hyperactivity disorder (ADHD). Once-daily methylphenidate CD is generally well tolerated and effective in the treatment of children and adolescents with ADHD. Methylphenidate CD resulted in superior control of ADHD symptoms compared with osmotic release oral system (OROS) methylphenidate over a time period corresponding to that of an average school day in a laboratory classroom. In 3-week clinical trials conducted in a community setting, methylphenidate CD was superior to placebo and noninferior to methylphenidate immediate-release (IR) in the treatment of children and adolescents with ADHD. Thus, methylphenidate CD should be considered an important primary treatment on its own or in addition to behavioral and psychosocial interventions, for when a reduction in ADHD symptoms is required during the school day in preference to the evening.
Comparison of the clinical efficacy of twice-daily Ritalin and once-daily Equasym XL with placebo in children with Attention Deficit/Hyperactivity Disorder. [2018]To compare the efficacy and safety of two methylphenidate (MPH) formulations--once-daily modified-release MPH (EqXL, Equasym XL) and twice-daily immediate-release methylphenidate (MPH-IR, Ritalin)--and placebo in children with Attention Deficit/Hyperactivity Disorder (ADHD).
Dexmethylphenidate--Novartis/Celgene. Focalin, D-MPH, D-methylphenidate hydrochloride, D-methylphenidate, dexmethylphenidate, dexmethylphenidate hydrochloride. [2018]Celgene has developed a chirally pure form of methylphenidate (Ritalin), called dexmethylphenidate [d-methylphenidate, d-methylphenidate hydrochloride, d-MPH; Focalin]. The drug has been launched in the USA and is undergoing registration in Canada for the treatment of children with attention-deficit hyperactivity disorder (ADHD). Dexmethylphenidate is the single isomer version of racemic methylphenidate (Ritalin), which contains the active d isomer of Ritalin. Dexmethylphenidate acts via the inhibition of reuptake of norepinephrine and dopamine. Research is ongoing to further clarify the mode of therapeutic action in ADHD. Dexmethylphenidate was developed with the aim of reducing drug load, adverse events and drug interactions. Dexmethylphenidate provides effective management of attention-deficit hyperactivity disorder at half the dose of Ritalin. In April 2000, worldwide rights (excluding Canada) to dexmethylphenidate were granted to Novartis. Celgene has also granted Novartis rights to all related intellectual properties and patents. Novartis will fund all remaining development and marketing expenses required for regulatory approval and commercialisation of dexmethylphenidate. Crystaal Corporation, the marketing division of Biovail Corporation International, has exclusive Canadian marketing rights for all formulations of dexmethylphenidate. Novartis launched dexmethylphenidate (Focalin) in the USA during Q1 2002. It is available as a D-shaped tablet (2.5, 5 and 10 mg doses). Novartis had planned to use the tradename Ritadex, however the FDA recommended an alternative name due to potential prescribing errors with Ritalin. The finalized tradename to be used is Focalin. In July 2001, a new drug submission was filed with Canada's Therapeutic Products Programme for dexmethylphenidate in the treatment of attention-deficit disorder and attention-deficit hyperactivity disorder. Novartis is also developing an extended-release version of chirally pure dexmethylphenidate. Dexmethylphenidate has been found to be effective and well tolerated in clinical trials, involving a total of 684 children with ADHD and in 15 healthy adult volunteers. Dexmethylphenidate is a schedule II drug.

Symptom control in children and adolescents with attention-deficit/hyperactivity disorder on switching from immediate-release MPH to OROS MPH Results of a 3-week open-label study. [2022]The aim of this study was to assess the impact of switching from immediate-release (IR) methylphenidate (MPH) to OROS MPH (CONCERTA, a once-daily long-acting MPH formulation, in children and adolescents with attention-deficit/hyperactivity disorder (ADHD).

[Utilization of methylphenidate(Ritalin) in France]. [2013]Methylphenidate (Ritalin) is the only psychostimulant approved in France and indicated in attention deficit hyperactivity disorder in children over 6 years. It is under restricted prescription and distribution conditions. As such, it requires a hospital initiated prescription from either a neurology, psychiatry or pediatric specialist and it is covered by the "narcotics" schedule. The French Pharmacovigilance database spontaneous adverse drug reactions reporting, since it was approved in 1995, were analyzed. 21 adverse drug reactions were reported. In 16 cases, methylphenidate was suspected. They were generally non-serious, mild side effects and in most cases promptly resolved. These results do not suggest methylphenidate misuse in France or an overuse in between 1300 and 4000 treated children, to date. Until more information is available concerning the long-term effects of methylphenidate, and in order to limit misuse, inappropriate or overuse, the current prescription and dispensing regulation should be maintained in France, and could well be developed in other countries.

The clinical impact of switching attention deficit hyperactivity disorder patients from OROS(®)-MPH to Novo-MPH ER-C(®): A paediatric practice review. [2021]In Canada, novo-methylphenidate extended-release capsules (Novo-MPH ER-C, Novopharm Limited, Canada) was approved as being bioequivalent to a current first-line treatment for attention deficit hyperactivity disorder (ADHD), CONCERTA (OROS-MPH, Janssen Inc, Canada). The present practice review was undertaken to determine whether bioequivalence of these products translates into therapeutic equivalence.
