Methylphenidate as a drug to increase energy levels long-term (when taken on a continual basis) - discussion

Methylphenidate (brand names Ritalin, Concerta, Methylin, Medikinet, Equasym XL, Quillivant XR, Metadate, and other) is a central nervous system (CNS) stimulant of the phenethylamine and piperidine classes that is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. Methylphenidate has been studied and researched for over 50 years and has a very good efficacy and safety record for the treatment of ADHD. 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.
