Answer:
Examples of stimulants are dextroamphetamine (Dexedrine, Dextrostat, ProCentra), lisdexamfetamine (Vyvanse) and methylphenidate (Concerta, Daytrana, Methylin, Ritalin). Common examples are caffiene and amphetamines.
Stimulants is an overarching term that covers many drugs including those that increase activity of the central nervous system and the body, drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects.
Stimulants were first used to treat asthma and obesity. Today, they're also prescribed to treat problems such as ADHD, ADD, depression, narcolepsy, and other problems.
