The U.S. Food and Drug Administration approved a new non-opioid pain medication developed by the Massachusetts-based company Vertex Pharmaceuticals on Thursday. The drug, which is called suzetrigine and will be sold under the brand name Journavx, is the first new type of pain medicine approved by the agency in more than 20 years.

A non-opioid pain medication made by Vertex Pharmaceuticals has received approval for adults from the Food and Drug Administration (FDA).

The Vertex drug is a milestone after a long history of unsuccessful efforts to develop painkillers without the addictive potential of opioids.
