The spread

20.7× estimated

These two figures may not measure the same thing

At 20.7×, the Medicare figure is 20 or more times what pharmacies pay. A gap that large means the two figures may not describe the same unit or product, or the price may have changed between their dates; check what each one covers before relying on the multiple.

Part D averages every strength and form sold under “Darunavir” into one figure, so it is not specific to this NDC.
