Connecticut Attorney General William Tong is leading a 44-state coalition in an antitrust lawsuit against 20 makers of generic drugs and 15 individuals, claiming the companies conspired to fix prices for more than 100 medications.

The lawsuit—filed May 10 in the U.S. District Court for the District of Connecticut—alleges Teva Pharmaceuticals USA Inc., Pfizer Inc., Sandoz Inc., Mylan Pharmaceuticals Inc. and other companies have conspired since at least 2012 to fix the prices on well-known drugs like Niacin ER tablets, Warfarin sodium tablets and Omega-3 acid ethyl esters. The drugs span all types, including tablets, capsules, suspensions, creams, gels, ointments and classes, including statins and antidepressants.
