Suzetrigine: A New Non-Opioid Analgesic Option With Potential Implications for Serious Illness Care

In this letter, the authors evaluate the potential of suzetrigine, a newly U.S. Food and Drug Administration-approved selective NaV1.8 sodium channel inhibitor, as a novel nonopioid alternative for managing moderate-to-severe pain. By targeting peripheral sensory neurons and avoiding the central nervous system, suzetrigine offers a favorable safety profile that bypasses typical opioid-related risks such as respiratory depression, sedation, and tolerance. While clinical trials demonstrate its noninferiority to hydrocodone/acetaminophen in acute postsurgical settings, the authors highlight significant barriers to its use in palliative and hospice care. These limitations include a lack of evidence in patients with serious illness, a current safety restriction of 14 days of use, and a high cost of approximately $15.50 per tablet. Consequently, while suzetrigine represents a significant pharmacological advancement, its current utility is likely limited to short-term acute pain crises until further data support its long-term application in serious illness management.
