On Tuesday, the Biden administration released a list of 10 medications that it's planning to negotiate prices for Medicare in an effort to bring down the costs of some of the most expensive drugs. It's part of a reform included in the Inflation Reduction Act. Many on the list are life-saving drugs that treat diabetes, cancer and other major health problems.|The new prices that the federal government will eventually negotiate for these prescription drugs won't actually go into effect until 2026, and that's only if it doesn't get tied up in court with drugmakers. Six pharmaceutical companies who have filed lawsuits against the administration are calling these provisions unconstitutional. Juana Summers speaks with NPR's pharmaceuticals correspondent Sydney Lupkin and Deepa Shivaram at the White House about the battle lines being drawn between the Biden Administration and pharmaceutical companies.
