Pharmacy benefit manager Express Scripts Holding Co. said it would favor drugmaker Mylan Inc.’s versions of the EpiPen lifesaving allergy treatment over the allergy auto-injectors of other companies.

Express Scripts Holding Co. – the largest U.S. pharmacy benefit manager – said prescription drug spending for its members slowed to less than 4 percent in 2016.
