Pharmaceutical Information
Drug Name Methylphenidate
Drug ID BADD_D01431
Description Methylphenidate is a central nervous system stimulant used most commonly in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) and for narcolepsy. Also known as the marketed products Ritalin, Concerta, or Biphentin, methylphenidate is used with other treatment modalities (psychological, educational, cognitive behaviour therapy, etc) to improve the following group of developmentally inappropriate symptoms associated with ADHD: moderate-to-severe distractibility, short attention span, hyperactivity, emotional lability, and impulsivity. Long-acting formulations of psychostimulants such as methylphenidate, [DB01576], and [DB01255] are considered the most effective and widely used treatment for ADHD, and are considered first-line options for children, adolescents, and adults as recommended by CADDRA (Canadian ADHD Resource Alliance). [L6037] CADDRA recommends the use of methylphenidate due to long term studies, of over twenty years in duration, which show methylphenidate is safe and effective.
Indications and Usage Methylphenidate is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years of age and older and for the treatment of narcolepsy.
