Is Vyvanse worth more than Dexedrine spansules if the coverage hours feel similar?

If coverage hours on Dexedrine spansules and Vyvanse feel similar, that still does not show that Vyvanse is or is not worth more. Official sources do not support a cost-per-functional-hour comparison, and feeling similar hours is not the same as the chart durations being identical. CADDRA lists approximate durations: Dexedrine spansules about 6 to 8 hours, Vyvanse about 13 to 14 hours as a prodrug, with the footnote that estimates are individual and should not replace clinician judgement.
