title: Stability of Adderall in extemporaneously compounded oral liquids.
abstract: The short-term stability of Adderall in three extemporaneously compounded oral liquids was studied. Three suspensions of Adderall 1 mg/mL were prepared from commercially available 10-mg Adderall tablets with Ora-Sweet, Ora-Plus, and a 1:1 mixture of Ora-Sweet and Ora-Plus. Each suspension was stored in the dark in a stability chamber at 25 degrees C and 60% relative humidity for 30 days. The stability of the active drug (a mixture of levoamphetamine and dextroamphetamine salts) in each of the three vehicles was determined immediately after preparation and at 10, 20, and 30 days by using gas chromatography-mass spectrometry (GCMS). No significant changes in concentrations of either amphetamine isomer occurred during the 30-day study period. Visual inspection of samples revealed no changes in color or odor. Extemporaneously compounded liquid oral formulations of Adderall 1 mg/mL in Ora-Sweet, Ora-Plus, or a 1:1 mixture of Ora-Sweet and Ora-Plus were stable for at least 30 days at 25 degrees C and 60% relative humidity.
