Description
George Gadalla and co-authors chart how a key ADHD drug was handed out in Australia before and during long supply shortages. Their 2026 study uses national dispensing records from the start of 2020 to the spring of 2026. The drug, methylphenidate, is a mainstay for attention deficit hyperactivity disorder.
The team counts fills per head of population and in daily-dose units. They mark the months when the national shortage list flagged the drug. A special rule lets overseas brands stand in during a shortage, and the study weighs how much of the supply those stand-ins carried. It also sets the drug beside other ADHD medicines, splits the counts by strength and form, and times the lag from approval of a stand-in to its funded listing.
