NEW YORK (AP) — Drugs that treat Type 2 diabetes, HIV and arthritis are among 15 new medications chosen for a Medicare drug price negotiation program that allows the federal government to haggle directly with drug manufacturers, the Trump administration said Tuesday.

The drugs selected include some of the medications on which Medicare spends the most money. That means the deals negotiated this year have the potential to deliver significant savings to taxpayers when they go into effect in 2028.

“For too long, seniors and taxpayers have paid the price for skyrocketing prescription drug costs,” Centers for Medicare and Medicaid Services Administrator Dr. Mehmet Oz said in a statement Tuesday. “Under President Trump’s leadership, CMS is taking strong action to target the most expensive drugs in Medicare, negotiate fair prices, and make sure the system works for patients — not special interests.”

The federal government had until Feb. 1 to announce its list of 15 drugs. The negotiations take place under a 2022 law that allows Medicare to haggle over the price it pays on the most popular and expensive prescription drugs used by older Americans.
