Abstract

Introduction: Acute pain is a constant reality in clinical practice.Patients come in because of their pain, surgeons cause it to happen, and a significant part of the care after surgery involves managing this pain.Yet the medications available for treatment are pretty much the same as always, including NSAIDs, paracetamol, local anesthetics, and opioids.There are several limitations when it comes to the use of opioid drugs, such as sedation, vomiting, or dependence.On the other hand, suzetrigine is a completely different method, since it uses a different mechanism of action.It acts on the peripheral part of the pain pathway by blocking sodium channels.Methods: A systematic review of the existing literature was conducted, comprising preclinical research and randomized phase II and III clinical trials in the acute postoperative pain setting for suzetrigine.Results: The NaV1.8 blocker showed superiority over placebo on the primary endpoint of pain intensity.In contrast to hydrocodone/acetaminophen, the findings were more varied, with some evidence of equivalence in particular operational settings but slightly reduced efficacy in others.Earlier time-to-relief and lower rescue analgesic consumption were also noted compared to placebo.Adverse events were mostly mild and transient.The data we have, however, come from short trials.Conclusions: Suzetrigine has been found to be a good potential candidate for an effective acute pain treatment, not being an opioid analgesic.Further…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
