Methylphenidate has been studied and researched for over 50 years and has a very good efficacy and safety record for the treatment of ADHD.〔http://www.patient.info/health/attention-deficit-hyperactivity-disorder-leaflet〕 The original patent was owned by CIBA, now Novartis Corporation. It was first licensed by the U.S. Food and Drug Administration (FDA) in 1955 for treating what was then known as hyperactivity. Prescribed to patients beginning in 1960, the drug has become increasingly prescribed since the 1990s, when the diagnosis of ADHD itself became more widely accepted. Between 2007 and 2012 methylphenidate prescriptions increased by 50% in Britain and in 2013 global methylphenidate consumption increased to 2.4 billion doses, a 66% increase compared to the year before. The US continues to account for more than 80% of global consumption.〔http://www.bbc.com/news/health-23674235〕〔http://www.pharmaceutical-journal.com/news-and-analysis/news-in-brief/narcotics-monitoring-board-reports-66-increase-in-global-consumption-of-methylphenidate/20068042.article〕 ADHD and other similar conditions are believed to be linked to sub-performance of the dopamine and norepinephrine functions in the brain, primarily in the prefrontal cortex, responsible for executive function (e.g., reasoning, inhibiting behaviors, organizing, problem solving, planning, etc.). Methylphenidate's mechanism of action involves the inhibition of catecholamine reuptake, primarily as a dopamine reuptake inhibitor. Methylphenidate acts by blocking the dopamine transporter and norepinephrine transporter, leading to increased concentrations of dopamine and norepinephrine within the synaptic cleft. This effect in turn leads to increased neurotransmission of dopamine and norepinephrine. Methylphenidate is also a 5HT1A receptor agonist. == Uses == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Methylphenidate」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
