The website, TrumpRx, lists many medicines at prices higher than paid in the US, which is seen as proof of his efforts to reduce U.S. drug prices across the world. However, Wayne Winegarden, a medical economist at the right-leaning Pacific Research Institute think tank, criticised the website for reflecting direct-to-consumer cash prices, not what most Americans pay. The White House defended the administration's efforts, stating that some medicines are now "300% to 600%" cheaper. The UK's National Health Service updates its payouts monthly by the cost-control agreements and other assessments. The cost of these deals is based on the cost of each prescription medicine purchased by the private or government-sponsored insurance.
