This product (Dyanavel XR) is an oral suspension (i.e., a drug that is suspended in a liquid and taken by mouth) that contains 2.5 mg/mL of amphetamine base. The amphetamine base contains dextro- to levo-amphetamine in a ratio of 3.2:1, which is approximately the ratio in Adderall. The product uses an ion exchange resin to achieve extended release of the amphetamine base.
  1. For uniformity, molecular masses were calculated using the Lenntech Molecular Weight Calculator[1] and were within 0.01g/mol of published pharmaceutical values.
  2. Amphetamine base percentage = molecular massbase / molecular masstotal. Amphetamine base percentage for Adderall = sum of component percentages / 4.
  3. dose = (1 / amphetamine base percentage) × scaling factor = (molecular masstotal / molecular massbase) × scaling factor. The values in this column were scaled to a 30 mg dose of dextroamphetamine sulfate. Due to pharmacological differences between these medications (e.g., differences in the release, absorption, conversion, concentration, differing effects of enantiomers, half-life, etc.), the listed values should not be considered equipotent doses.
