WASHINGTON (AP) — Taxpayers are expected to save billions after the Biden administration inked deals with pharmaceutical companies to knock down the lists prices for 10 of Medicare’s costliest drugs . But how much older Americans can expect to save when they fill a prescription at their local pharmacy remains unclear, since the list cost isn't the final price people pay. After months of negotiations with manufacturers, list prices will be reduced by hundreds — in some cases, thousands — of dollars for 30-day supplies of popular drugs used by millions of people on Medicare, including blood thinners, diabetes drugs and blood cancer medications.

The reductions, which range between 38% and 79%, take effect in 2026. “I've been waiting for this moment for a long long time," President Joe Biden said Thursday, during his first policy-oriented appearance with Vice President Kamala Harris since leaving the presidential race. “We pay more for prescription drugs, it’s not hyperbole, than any advanced nation in the world.

" Taxpayers spend more than $50 billion yearly on the 10 drugs, which include popular blood thinners Xarelto and Eliquis and diabetes drugs Jardiance and Januvia. With the new prices, the administration says savings are expected to total $6 billion for taxpayers and $1.5 billion overall for some of the 67 million people who rely on Medicare.

Details on those calculations, however, have not been released. And the White House said it could not provide an avera.
