A federal judicial panel sent more than 140 lawsuits filed over heartburn medication Zantac to the Southern District of Florida, where U.S. District Judge Robin Rosenberg will preside over them.

In a Thursday order, the U.S. Judicial Panel on Multidistrict Litigation cited the convenience and resources of the Southern District of Florida, adding that Rosenberg, a 2014 appointee of President Obama, has not handled an MDL before.
