ABSTRACT
PURPOSE: The aim of this study was to describe trends in attention deficit hyperactivity disorder (ADHD) drugs consumption in Israel (Ritalin, Concerta, Daytrana, Vyvanse, Focalin, and Adderall) over the 8 years, 2005-2012, and to explore explanations for changes in amounts and patterns of the utilization. METHODS: Data for the period from 2005 to 2012 were extracted from the database maintained by the Israel Ministry of Health's Pharmaceutical Administration. The data were converted into a defined daily dose (DDD) per 1000 inhabitants per day. RESULTS: Consumption of all ADHD drugs covered by Israel's national health care system doubled over the study period, from 4.02 DDD/1000 inhabitants/day in 2005 to 9.92 DDD/1000 inhabitants/day in 2012. This rise was largely due to a fivefold increase in Concerta consumption (from 0.46 DDD/1000 inhabitants/day in 2005 to 2.28 DDD/1000 inhabitants/day in 2012) and a threefold increase in Ritalin consumption (from 1.43 DDD/1000 inhabitants/day in 2005 to 4.84 DDD/1000 inhabitants/day in 2012). Adderall (amphetamine mixed salts) consumption rose by 30% for the same period. A substantial trend was noted for increased utilization of high-dose formulations together with proportional decline in low-dose consumption. In the same period, cost of the medications has been reduced an average by 20-25%. CONCLUSIONS: There has been a drastic rise in ADHD drugs consumption in Israel over 2005-2012. This has been associated with substantial reduction in cost and changes in the pattern of prescribing that characterized by increased prescription of high-dose long-acting preparations of ADHD drugs and decreased prescription of their low-dose, short-acting formulations.
