Background & Objective: Methylphenidate is one of the most common medications used for treatment of attention-deficit/hyperactivity disorder (ADHD). The administration of methylphenidate, through blocking of dopamine receptors and increment of extracellular dopamine levels, leads to escalation in central nervous system activity. Numerous studies investigated the effect of methylphenidate on bod...
BACKGROUND Non-medical use of methylphenidate is increasing. Little is known about potential acute medical complications associated with recreational use of methylphenidate. STUDY AIM To identify medical problems associated with methylphenidate abuse. METHODS Retrospective case series of methylphenidate abuse cases presenting to an inner city emergency department. RESULTS We identified 14...
Background at least 5% of school-aged children. Boys are more commonly affected. Besides imposing large expenses on society health care system, ADHD may influence occupational, social and educational aspects of child's life, thus, establishing an appropriate therapy is of utmost importance . Materials and methods experiment (receiving methylphenidate) and control (methylphenidate and behavioral...
OBJECTIVE Neurological soft signs are very common in children with the attention deficit hyperactivity disorder (ADHD), and the first line medication of this disorder is methylphenidate. The aim of the study was to assess the effect of methylphenidate on the neurological soft signs in children and adolescents suffering from ADHD depending on the dose of methylphenidate. METHODS Thirty five pa...
Background: Attention-deficit/hyperactivity disorder (ADHD) is a common and mostly chronic mental health condition that affects children, adolescents, and adults. Stimulants and atomoxetine are first-line agents for the treatment of ADHD. Despite the impressive track record of stimulants in the treatment of ADHD, they fail in 25% of patients due to lack of efficacy or the emergence of unwanted ...
The National Toxicology Program (NTP) Center for the Evaluation of Risks to Human Reproduction (CERHR) conducted an evaluation of the potential for methylphenidate to cause adverse effects on reproduction and development in humans. Methylphenidate was selected for evaluation because of 1) widespread usage in children, 2) availability of developmental studies in children and experimental animals...
BACKGROUND Although accumulating evidence suggests that arousal pathways in the brain play important roles in emergence from general anesthesia, the roles of monoaminergic arousal circuits are unclear. In this study, the authors tested the hypothesis that methylphenidate (an inhibitor of dopamine and norepinephrine transporters) induces emergence from isoflurane general anesthesia. METHODS Us...
Patients with Attention-Deficit/Hyperactivity disorder (ADHD) have higher smoking rates, a younger age of smoking onset, and increased difficulty to stop smoking as compared to controls. Methylphenidate induced acute effects of increased smoking in laboratory studies, but long-term effects are unknown. We studied the acute and long-term relationship between methylphenidate use and tobacco consu...
BACKGROUND There is no conclusive evidence that stimulants have beneficial effects on major associated outcome parameters, particularly school performance. We assessed the differences in school performance among children using methylphenidate at the end of primary school in relation to various parameters of methylphenidate use. METHODS We linked children from a pharmacy prescription database ...
Previous studies have demonstrated that methylphenidate, MDMA (3,4-methylenedioxymethamphetamine), and other psychostimulants exert stimulant-like subjective effects in humans. Furthermore, MDMA and methylphenidate substitute for the discriminative stimulus effects of psychostimulants, such as amphetamine and cocaine, in animals, which suggests that MDMA and methylphenidate may produce similar ...
