Suzetrigine for Opioid-Sparing Postoperative Analgesia Following Transvaginal Pelvic Reconstructive Surgery

29. maj 2026 opdateret af: Anne Lenore Ackerman, University of California, Los Angeles
Suzetrigine is a selective NaV1.8 inhibitor that provides peripheral analgesia without opioid-related CNS effects. This single-center stepped-wedge randomized clinical trial evaluates whether a suzetrigine-based postoperative analgesic regimen provides non-inferior pain control compared with standard opioid-inclusive care following transvaginal pelvic reconstructive surgery. The study will enroll 120 participants and assess pain, opioid consumption, adverse events, and functional recovery.

Detaljeret beskrivelse

Suzetrigine has demonstrated analgesic efficacy comparable to hydrocodone/acetaminophen in Phase III trials and is FDA-approved for acute pain. This trial represents the first evaluation of a NaV1.8 inhibitor in pelvic reconstructive surgery. Participants will receive either suzetrigine or standard opioid-inclusive postoperative care according to a stepped-wedge randomization schedule. Pain scores, medication use, and adverse events will be collected at 48 hours, 1 week, and 6 weeks postoperatively.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Suzetrigine-Based Regimen
Participants receive suzetrigine as part of a multimodal postoperative analgesic regimen. Suzetrigine is administered as a loading dose on the morning of surgery followed by twice-daily dosing for 7 days, in combination with scheduled acetaminophen and ibuprofen.
Medicin: Suzetrigine

Loading dose: 100 mg orally on the morning of surgery

Maintenance dose: 50 mg orally every 12 hours for 7 days

Co-administered medications: Scheduled acetaminophen and ibuprofen

Mechanism: Selective NaV1.8 sodium channel inhibitor acting on peripheral nociceptive neurons

Purpose: Opioid-sparing postoperative analgesia

Medicin: Scheduled Acetaminophen and Ibuprofen
Participants in both study arms will receive scheduled acetaminophen and ibuprofen as part of standard multimodal postoperative analgesia. These medications are administered routinely following transvaginal pelvic reconstructive surgery to reduce baseline pain, minimize opioid requirements, and support enhanced recovery.
Aktiv komparator: Standard Opioid-Inclusive Analgesic Regimen
Participants receive standard postoperative pain management consisting of scheduled acetaminophen and ibuprofen, with opioid analgesics available as needed per routine clinical care.
Medicin: Scheduled Acetaminophen and Ibuprofen
Participants in both study arms will receive scheduled acetaminophen and ibuprofen as part of standard multimodal postoperative analgesia. These medications are administered routinely following transvaginal pelvic reconstructive surgery to reduce baseline pain, minimize opioid requirements, and support enhanced recovery.
Medicin: Opioid Analgesics (Tramadol or Oxycodone)

Tramadol: 50 mg orally every 4-6 hours as needed OR

Oxycodone: 5 mg orally every 4-6 hours as needed

Co-administered medications: Scheduled acetaminophen and ibuprofen

Purpose: Standard postoperative analgesia per institutional protocol
