Prior to the settlement announcement, Pradaxa was one of the top drugs targeted in mass tort advertising as measured by ad spending. Advertising volumes peaked in May 2014 - the month the settlement was announced.
Since then, ad volumes had largely declined until March.
The Goldwater ad below also mentions blood thinners generally -- presumably including Bristol-Myers Squibb and Pfizer's Eliquis in addition to Xarelto and Pradaxa -- and ran 14 times in March.
