In another study, investigators found that children with ADHD who took once-daily, extended release formulations of Concerta saw greater improvements during the school day than those who took that formulation of Metadate CD. The treatment results, however, were similar between the two groups in the afternoon.
However, with a half-life of 2-3 hours, multiple doses are necessary during the school day Recently, the Food and Drug Administration approved several extended-release forms with the brand names Concerta, Metadate CD, and Ritalin LA.
Both Ritalin LA, which has not yet been approved by the Food and Drug Administration, and Metadate CD, which is already on the market, are designed to replace twice-daily dosing of Ritalin to provide 8 hours of coverage.
