A new pain relief drug, suzetrigine, is a prescription pill that’s taken every 12 hours after a larger starter dose. It will be sold under the brand name Journavx.

The prescription pills, sold under the brand name Journavx and made by Vertex Pharmaceuticals, are taken twice a day and represent the first new class of pain medications in 20 years—and the first non-opioid painkiller since that class first appeared on the market in the 1980s.

This milestone marks a breakthrough after unsuccessful attempts to develop painkillers without the addictive potential of opioids.
