Ritalin LA (Methylphenidate Hydrochloride Extended Release) - Summary



Drug Dependence

Ritalin LA should be given cautiously to patients with a history of drug dependence or alcoholism. Chronic abusive use can lead to marked tolerance and psychological dependence with varying degrees of abnormal behavior. Frank psychotic episodes can occur, especially with parenteral abuse. Careful supervision is required during withdrawal from abusive use, since severe depression may occur. Withdrawal following chronic therapeutic use may unmask symptoms of the underlying disorder that may require follow-up.



Methylphenidate hydrochloride is a central nervous system (CNS) stimulant.

Ritalin LA® (methylphenidate hydrochloride) extended-release capsules is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD).

Clinical Trials Related to Ritalin LA (Methylphenidate)

Methylphenidate Study in Breast or Gastrointestinal Cancer Patients [Terminated]
The goal of this clinical research study is to see if the drug OROS Methylphenidate HCl (Concerta) can help to control fatigue in patients with breast, gastrointestinal, lymphoma, myeloma or lung cancer who are going through chemotherapy or hormonal treatment or have completed chemotherapy or hormonal treatment in the last 12 months. The safety of this drug will also be studied. Another goal of the study is to see how certain cytokines change while patients undergo chemotherapy or hormonal treatment.

Study of the Effect of Individualizing Daytrana Wear-times on Sleep in Children With ADHD [Completed]
Methylphenidate may improve sleep in children with ADHD. By leaving Daytrana (methylphenidate) patch for a longer time then 9 hours, many children report short sleep latencies and better quality of sleep.

The Effect of Methylphenidate on Non-motor Symptoms and Postural Control in Parkinson's Disease. [Terminated]
This project aims to determine if methylphenidate can improve deficits in attention and symptoms of orthostatic hypotension, two common non-motor symptoms, in patients with Parkinson's Disease. This project also seeks to evaluate the effect of methylphenidate on postural control in these patients, a debilitating motor symptom that places patients at an increased risk of falling. This study will build on existing data to support a new indication for the use of methylphenidate in Parkinson's Disease. Using standard and objective evaluations, this study will quantify the effect of methylphenidate at two doses on attention levels, orthostatic hypotension, and measures of postural control. Phase I of the study will compare methylphenidate 10mg three times daily to placebo and Phase II of the study, for those tolerating the lower dose in Phase I, will compare methylphenidate 20mg three times daily to placebo. By incorporating two different doses, the study also seeks to determine if any improvements are dose-related. Secondary endpoints will include safety assessments (adverse event monitoring and vital signs) performed every 30 minutes following supervised drug administration. Visual analog scales will be presented to each participant before treatment and following the final dose of each treatment to assess changes in fatigue. A secondary task will be added to postural tests to assess the influence of cognitive processes. It is hypothesized that methylphenidate will demonstrate a significant beneficial effect on all outcomes. It is projected that objective improvements will be observed following treatment with methylphenidate at both doses (10 and 20mg three time daily) when compared to placebo. It is further hypothesized that the effects will be dose-related and therefore more profound with higher doses.

A Study to Explore Plasma Levels of CONCERTA, Ritalin-SR and Novo-Methylphenidate ER-C in Healthy Volunteers [Completed]

Ritalin, Memory and Attention in MCI: a Behaviour-EEG Study [Recruiting]
Traditionally, memory impairments in the elderly population are treated using cholinesterase inhibitors, although impairments remain after treatment. Dopamine (DA) is also involved in cognition and is especially of interest in healthy ageing because of the role in processing speed and cognitive control. To what extent dopamine treatment improves memory and attention in older impaired individuals is unknown. However, such an effect is conceivable because of the close relationship between memory and attention in aging and since improved processing speed and cognitive control may lead to improved memory. The investigators aim to examine, in the impaired older population, whether a treatment using methylphenidate, a DA re-uptake inhibitor that enhances DA, improves attention and memory. The study will be conducted according to a cross-sectional, double-blind, placebo-controlled, 2-way cross-over design. 20 male and female patients with Mild Cognitive Impairment (MCI), amnestic type, aged above 60 years of age; 20 male and female patients with MCI, non-amnestic type, will be recruited from the Orbis Medical Centre. Participants will be treated once with 20 mg methylphenidate (MPH) and once with placebo. All medications will be administered orally with a capsule. The treatment order will be established by counterbalancing.
