Ritalin LA (Methylphenidate Hydrochloride Extended Release) - Summary

 
 



BOX WARNING

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.

Efficacy of lisdexamfetamine dimesylate in children with attention-deficit/hyperactivity disorder previously treated with methylphenidate: a post hoc analysis. [2011.11.04]
ABSTRACT: BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a common neurobehavioral psychiatric disorder that afflicts children, with a reported prevalence of 2.4% to 19.8% worldwide. Stimulants (methylphenidate [MPH] and amphetamine) are considered first-line ADHD pharmacotherapy. MPH is a catecholamine reuptake inhibitor, whereas amphetamines have additional presynaptic activity. Although MPH and amphetamine can effectively manage ADHD symptoms in most pediatric patients, many still fail to respond optimally to either. After administration, the prodrug stimulant lisdexamfetamine dimesylate (LDX) is converted to l-lysine and therapeutically active d-amphetamine in the blood. The objective of this study was to evaluate the clinical efficacy of LDX in children with ADHD who remained symptomatic (ie, nonremitters; ADHD Rating Scale IV [ADHD-RS-IV] total score > 18) on MPH therapy prior to enrollment in a 4-week placebo-controlled LDX trial, compared with the overall population... CONCLUSION: In this analysis, children with significant clinical ADHD symptoms despite MPH treatment improved during treatment with LDX and experienced similar improvements in their symptoms as the overall study population. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00556296.

Comparison of the Efficacy of Two Different Modified Release Methylphenidate Preparations for Children and Adolescents with Attention-Deficit/Hyperactivity Disorder in a Natural Setting: Comparison of the Efficacy of Medikinet((R)) Retard and Concerta((R))-a Randomized, Controlled, Double-Blind Multicenter Clinical Crossover Trial. [2011.10]
Abstract Objective: The comparison of the efficacy of Medikinet((R)) retard and Concerta((R)) trial was a multisite, randomized, double-blind, crossover trial that aimed at comparing the effects of two different modified release methylphenidate preparations (Medikinet retard: 50% immediate release (IR); Concerta: 22% IR) in a natural setting across the day in 113 randomized children and adolescents with attention-deficit/hyperactivity disorder (age range 6-16 years)...

Clinical Trials Related to Ritalin LA (Methylphenidate)

A Comparative Effectiveness Study Evaluating OROS® Methylphenidate HCl, Ritalin® (Methylphenidate HCl), and Placebo for the Treatment of Attention Deficit Hyperactivity Disorder in Children [Completed]

An Effectiveness and Safety Study Evaluating OROS® Methylphenidate HCl, Ritalin® (Methylphenidate HCl) and Placebo in Children With Attention Deficit Hyperactivity Disorder [Completed]
The purpose of this study is to provide data on the effectiveness of the OROS® Methylphenidate HCl formulation compared to placebo and standard immediate-release Ritalin® with respect to improving attention and behavior, and decreasing hyperactivity in children with Attention Deficit Hyperactivity Disorder (ADHD). Both OROS® Methylphenidate HCl and Ritalin® contain the central nervous system stimulant, methylphenidate HCl. The safety associated with the two methylphenidate formulations will also be compared with placebo.

A Double-Blind Randomized, Placebo-Controlled, Crossover Study of Single Doses of OROS Methylphenidate Hydrochloride (CONCERTA) and Long-Acting Methylphenidate Hydrochloride (RITALIN LA) in Healthy Adults [Completed]
This is a double-blind, placebo-controlled study, three-period crossover study to examine the likeability of a single dose of OROS MPH (CONCERTẢ 90mg) and a single dose of Long-acting MPH (RITALIN LẢ 90mg). Hypotheses are as follows:

Hypothesis 1: OROS-MPH (CONCERTẢ) will be later than SODOS-MPH (RITALIN LẢ) in its Tmax (time to Cmax).

Hypothesis 2: The subjective feelings of detection and likeability would be greater for SODOS-MPH (RITALIN LẢ) than for an equivalent total dose of OROS-MPH (CONCERTẢ).

A Multicenter Study Comparing the Efficacy and Safety of OROS® Methylphenidate HCl, Ritalin® (Methylphenidate HCl) and Placebo in Children With Attention Deficit Hyperactivity Disorder [Completed]
The purpose of this study is to evaluate the efficacy and safety of OROS® Methylphenidate HCl as compared with placebo and standard immediate-release Ritalin® (taken three time per day) for the treatment of Attention Deficit Hyperactivity Disorder in children. Both OROS® Methylphenidate HCl and Ritalin® contain the central nervous system stimulant, methylphenidate HCl.

Naturalistic Substitution of Concerta in Adult Subject With ADHD Receiving Immediate Release Methylphenidate [Completed]
This is a single-blind study looking at the efficacy and satisfaction of Concerta substitution in adult subjects with ADHD receiving immediate release methylphenidate. Subjects will be administered a maximum dose of 1. 3mg/kg/day of either methylphenidate or Concerta. The specific hypotheses of this study are:

Hypothesis 1: ADHD symptomatology in adults with DSM-IV, ADHD will continue to be controlled in patients switched from MPH IR TID to Concerta.

Hypothesis 2: Patient satisfaction will not decrease in patients switched from MPH IR TID to Concerta (ie., all patients will be equally or more satisfied on Concerta as compared with MPH IR TID.
