Brand Name of Dextroamphetamine-Amphetamine
The brand name for dextroamphetamine-amphetamine mixed salts is Adderall, with the extended-release formulation marketed as Adderall XR. 1, 2
Available Formulations
Immediate-release formulation: Marketed as Adderall, containing a 3:1 ratio of dextroamphetamine to levoamphetamine salts 2
Extended-release formulation: Marketed as Adderall XR, which uses a dual-release mechanism with immediate-release pellets that deliver half the dose upon ingestion and delayed-release pellets that release the remaining dose approximately 4 hours later 2
Important Distinction
Note that dextroamphetamine alone (without the mixed amphetamine salts) is marketed under different brand names, specifically Dexedrine and ProCentra, which are single-entity dextroamphetamine products rather than the mixed amphetamine salt combination 3. These are distinct medications from Adderall, which contains both dextroamphetamine and levoamphetamine in combination.
Clinical Characteristics
Adderall XR provides approximately 12 hours of symptom coverage with onset of action within 1.5 hours 2
The usual starting dose for adults is 10 mg once daily in the morning, with titration in 5 mg weekly increments up to a maximum of 50 mg daily 1, 4
Both formulations are DEA Schedule II controlled substances due to high potential for abuse 5
