14 June 2019 - The rule, set to take effect 9 July, is one of the most visible efforts by the Trump administration to try to address high drug prices.

Three of the nation’s major drug manufacturers sued the Trump administration on Friday to block a rule that would force them to put the price of their drugs in television advertisements beginning this summer.

The lawsuit, filed Friday in federal court in Washington, D.C., by Merck, Eli Lilly and Amgen, as well as a trade group for advertisers, argues that the rule is illegal because it violates the companies’ First Amendment rights. It also claims that the ad disclosures, which require drug manufacturers to include the list price of any drug that costs more than $35 a month, could mislead consumers because insurers often cover the bulk of a drug’s cost.
