Stimulant medication trends were organized by drug subclass, year, age group, gender, country, prescriber specialty, diagnosis, and expenditures. Results: Major recent trends are as follows: amphetamine medication usage has prominently surpassed methylphenidate, total stimulant prescription sales to adults have surpassed those for youth, and more adult women are prescribed stimulants than adult men. Conclusion: Stimulant medication treatmentparticularly of amphetaminesis rapidly expanding in the United States.
