Specializes in Child Psychiatry

Adderall (dextroamphetamine and racemic amphetamine) XR is an: Amphetamine preparation for treatment of adhd. The 'mean elimination half-life' for d-amphetamine is 10-13 hours (faster in children) and it should completely clear within 24 hours. There is no unexpected accumulation at steady state in children. Alkaline urine phs result in reduced renal elimination, and acidic phs and high flow rates result in increased renal elimination. Best regards.
