On Jan. 30, the Food and Drug Administration approved a novel, non-opioid drug to treat moderate to severe short-term pain in adults. The first new painkiller to hit the market since 1998, suzetrigine — also known by the brand name Journavx — relieves pain without the risk of addiction that comes with opioid-based drugs.

We feel pain when neurons at the site of an injury send electrical signals to the brain indicating something’s wrong. Suzetrigine works by interrupting a single sodium channel in those nerve cells, preventing the message from reaching the brain and generating a feeling of pain. Opioids, on the other hand, block pain signals by targeting opioid receptors while at the same time spurring a flood of dopamine, which triggers euphoria. This is why opioid pain medications carry a high risk of addiction. Suzetrigine causes no such feelings of euphoria.

Some anesthetics, like ones used during dental procedures, also work by blocking sodium channels. But the body contains multiple types of sodium channels, and drugs like lidocaine affect all of them. This means providers can only apply those anesthetics locally to prevent indiscriminate shut down of all sodium channels. Suzetrigine is the first pain reliever to safely and successfully target just one sodium channel across the body.

Big Picture: More than 720,000 people in the United States died due to an opioid overdose between 1999 and 2022, according to the Centers for Disease Control and Prevention. The ongoing opioid crisis has underscored a dire need for pain management options beyond those medications, which are both highly effective and addictive, and over-the-counter pills like Tylenol or Advil. Suzetrigine is approved for acute pain management like the type people require following surgery or injury. But it’s not yet clear whether drugs targeting sodium channels could one day address chronic pain, for which opioids remain a common treatment.
