U.S. prescription drug prices declined 3.1% from a year ago, marking the steepest drop since 1963. Although President Donald Trump claims credit via 'most favored nation' deals, experts note the price reduction is complex. Contributing factors include Medicare's ability to negotiate costs through policies like the Inflation Reduction Act, and market competition fueled by generic and biosimilar drugs.

Medicare Part D, which provides prescription drug coverage, has a 2026 average monthly premium of $34.50, a maximum annual deductible of $615, and an out-of-pocket cap of $2,100. The Inflation Reduction Act of 2022 limits insulin copays to $35 per month, and Part D covers 10 specific drugs with reduced costs. Coverage is structured through tiered pricing and stages, including deductible, initial coverage, and catastrophic phases.
