On January 30, 2025, the U.S. Food and Drug Administration (FDA) approved Journavx™ (suzetrigine), a first-in-class non-opioid analgesic, for the treatment of moderate to severe acute pain in adults. Acute pain is sudden onset, short duration discomfort due to tissue injury, trauma, surgery, or other medical conditions. It is often treated with pain relievers that may contain opioids. Journavx™ is a new alternative to opioids that reduces pain by selectively blocking a unique pathway in the nervous system, thereby inhibiting transmission of pain signals from the body to the brain.
The efficacy and safety of Journavx™ was evaluated in two randomized, double-blind, placebo- and active-controlled trials of 874 adult patients with moderate to severe acute pain following surgery. Patients were permitted to use ibuprofen in addition to their treatment medication if they had breakthrough pain. Both trials' results showed a statistically significant superior reduction in pain for those treated with Journavx™ compared to those in the placebo group. Patients treated with Journavx™ achieved a 47% reduction from baseline in their mean Numeric Pain Rating Scale (NPRS) scores while patients in the placebo group had a 31% reduction from baseline. Common adverse reactions include itching, rash, muscle spasms and increased blood level of creatine phosphokinase. Journavx™ cannot be used in patients taking medications that strongly inhibit CYP3A enzymes, including several antibacterial, antifungal, and antiviral medications and patients should also avoid food and drinks containing grapefruit while taking it.
