The American Society of Anesthesiologists (ASA) asked United States District Judge Madeline Cox Arleo on June 11 to see the “trade libel” suit filed by Pacira BioSciences two months ago for what it is: an egregious and unjustified public relations campaign that seeks to chill scientific research and debate about Pacira’s controversial drug EXPAREL (liposomal bupivacaine). In its case, Pacira disputes the conclusions of peer-reviewed articles and an editorial in the February 2021 issue of Anesthesiology that EXPAREL lacks a comparative benefit over standard bupivacaine, even though it costs 100 times as much.
