Brief Summary

Rib fractures cause a significant amount of pain and are associated with an increased risk of lung infections, long hospitalization, and increased cost. Effective pain control is the cornerstone of management to improve lung function and minimize complications. Most often this is done with a multimodal pain routine consisting of: acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), topical lidocaine, muscle relaxants, and opioids. However, suzetrigine is a promising alternative to treat acute pain associated with rib fractures. We think the addition of suzetrigine to a multimodal pain regimen will improve pain and decrease opioid use.

Outcome Measures

Primary Outcomes (2)

  • Evaluation of Pain

    Pain will be measured on a numerical pain scale from 0 (no pain) to 10 (most pain). Higher pain scores equate to worse outcomes.

    Through study completion of index hospitalization (up to 2 years)

  • Use of morphine and morphine equivalents

    Oral morphine equivalents (OME) - A study team member will do a chart review and collect morphine used by the patients.

    Through study completion of index hospitalization (up to 2 years)

Secondary Outcomes (4)

  • Epidural Administration

    Through study completion of index hospitalization (up to 2 years)

  • Time in the Hospital

    Through study completion of index hospitalization (up to 2 years)

  • Respiratory Complications

    Through study completion of index hospitalization (up to 2 years)

  • Mortality

    Through study completion of index hospitalization (up to 2 years)

Study Arms (2)

Suzetrigine arm

EXPERIMENTAL

The intervention arm will receive oral suzetrigine (100 mg loading dose followed by 50 mg every 12 hours).

Drug: Suzetrigine (SUZ)

Control arm

PLACEBO COMPARATOR

The control arm will receive placebo capsules matched to suzetrigine for oral administration.

Drug: Placebo

Interventions

The intervention arm will receive oral suzetrigine (100 mg loading dose followed by 50 mg every 12 hours).

Suzetrigine arm

The control arm will receive placebo capsules matched to suzetrigine for oral administration.

Control arm
