Well, it hasn't happened.

Drug prices keep going up despite a presidential-promise.

During the 2016 election campaign, President Trump repeatedly pledged to bring down prescription drug prices. At the end of May this year, he promised that drug companies would be announcing "massive" voluntary drug price cuts within two weeks.

Well, that hasn't happened.

A new analysis by the Associated Press finds there have been far more price hikes than cuts. While price increases did slow somewhat, the analysis found there have been 96 price hikes for every price cut in the first seven months of this year.

@AP analyzed 26,176 U.S. list price changes for brand-name prescription drugs from Jan. 1 through July 31 in the years 2015 through 2018, using data supplied by health information analytics firm Elsevier. This year through the end of July, there were 4,412 brand-name drug price increases and 46 price cuts, a ratio of 96-to-1.

So what's the analysis telling us? Well, it's showing us how hard it is to bring down drug prices, and that even the president of the United States isn't making a whole lot of headway | @heatinformatics
