President Trump announced the addition of 600 medicines to his online drugstore as he appeals to Americans concerned about high drug prices and affordability.

President Trump said on Monday that his online drugstore, TrumpRx, was adding more than 600 generic medications to its direct-to-consumer offerings.

At an event at the White House announcing the expansion, Mr. Trump was joined by representatives from several companies that will work with the administration on the initiative. Among them was Mark Cuban, the billionaire entrepreneur who has been one of the president’s most vocal political critics. Mr. Cuban runs an online pharmacy that specializes in offering low prices for generic drugs.

“We have the same thing, one thing, in common: We want to make people better, and keep them wealthy,” Mr. Trump said to Mr. Cuban.

Mr. Cuban, who opposed the president’s re-election campaign in 2024, on Monday praised what he called a “special partnership,” noting that Americans across the political spectrum want lower drug prices.

TrumpRx, a government website introduced in February, does not sell drugs directly. It is meant to help Americans find the lowest prices for their medications. The prices listed there are for people paying with their own money, though the site advises them to check whether they can pay less by going through insurance.

The other partners announced on Monday are Amazon’s pharmacy business and GoodRx, a site that allows consumers to compare prices for their drugs.
