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, molar masses were calculated using the Lenntech Molecular Weight Calculator[1] and were within 0.01 g/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.
