Medicare paid about what pharmacies pay.

Questions

Why is the comparison with Medicare for ZIOPTAN 0.0015% EYE DROP labelled estimated?
Beyond what the card shows, the records give these reasons: The Part D figure covers 2024-01-01 to 2024-12-31; the NADAC price is from the file of 2026-10-14. Part D spending basis, as the Part D record states it: Part D 2024 average spend per dosage unit for Zioptan / Tafluprost/PF: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's EA. Joined on brand name.
Why does this page start at 1 unit (EA)?
NADAC prices this product per EA, and the FDA NDC Directory lists its NDC as dosage form “SOLUTION/ DROPS” with route “OPHTHALMIC”. Only a tablet, capsule, lozenge or troche with route “ORAL”, or a tablet or film with route “SUBLINGUAL” or “BUCCAL”, starts at 30, and this is not one. NADAC’s EA for it may be a whole package (such as a kit, pen, syringe, vial or inhaler) or one dose inside it, and the files do not say which. So the card starts at 1 unit (EA) rather than guess how many make up a fill; change it to match your prescription.
