LANSING —Michigan Attorney General Dana Nessel joined a coalition of 44 attorneys general in announcing a lawsuit against Teva Pharmaceuticals and 19 of the country’s largest generic drug manufacturers on Monday.

The lawsuit, filed in the U.S. District Court for the District of Connecticut, seeks damages, civil penalties and actions by the court to restore competition to the generic drug market.

The suit alleges a “broad conspiracy” to artificially inflate and manipulate drug prices, reduce competition and unreasonably restrain trade for more than 100 different generic drugs.

“Each day, people across the U.S. turn to generic drugs as an affordable alternative to name-brand medication,” Nessel said. “Michigan patients count on drug manufacturers to keep their prices affordable for life-saving medications. And when they don’t, when they collude to raise prices and line their pockets at the expense of the health and well-being of our residents, my office will hold them accountable.”

The complaint names Teva, Sandoz, Mylan, Pfizer and 16 other generic drug manufacturers, spanning all types of drugs. In some cases, coordinated price increases were more than 1,000 percent.
