Allergan Plc sued Pfizer Inc. to cover any potential damages that the drugmaker might be forced to pay as a result of the hundreds of lawsuits it faces over its alleged role in the opioid crisis.
Allergan claims the allegations in the opioid litigation involve improper marketing and sale of sale of morphine drug Kadian in the years before it acquired the rights to it. Allergan, then known as Actavis Plc, acquired Kadian in December 2008 from a company that was later acquired by Pfizer.
