Accurate Education – Suzetrigine

Acute Pain:

Suzetrigine

With expected release in early 2025, a new option for the treatment of moderate-to-severe acute pain will become available. While still investigational, suzetrigine represents a novel non-opioid class of analgesic medications, the first new class of medicine to treat acute pain in over twenty years.

It is hoped that this new pain medication will offer an opportunity to not only lessen the experience of acute pain but also reduce the transition from acute to chronic pain. Additionally, there is preliminary evidence to suggest that it may also be effective for the treatment of diabetic peripheral neuropathy pain.

 

What is Suzetrigine?

Suzetrigine is a small-molecule, non-opioid analgesic that works to relieve moderate to severe pain by inhibiting pain signaling in the peripheral nervous system only, it does not enter the central nervous system (spinal cord or brain). Because of this limited area of activity, suzetrigine is not expected to allow potential for addiction, nor is it expected to contribute to accidental overdose if combined with opioids. Suzetrigine is being developed by Vertex Pharmaceuticals and has completed two Phase III trials.

Clinical Trials of Suzetrigine

Two phase 2 clinical trials of suzetrigine have’been conducted involving participants with acute pain after abdominoplasty (tummy tuck) or bunionectomy. As compared to placebo, suzetrigine was found to be effective over 48 hours for the acute pain associated with these conditions. Side effects, including headache and constipation, were common but only mild to moderate severity. (ClinicalTrials.gov numbers, NCT04977336 and NCT05034952).

 

Acute Pain

Acute pain is the first response to damaged tissue, followed by inflammation that triggers swelling of the area and promotes tissue repair However, if the pain persists for more than 3 months, it is defined as chronic and it becomes a pathological condition in itself.  This temporal parameter is used to define the distinction between acute and chronic pain because there are no biomarkers or measurable physiological conditions that distinguish acute from chronic pain.

 

Transitioning from Acute to Chronic Pain

How Suzetrigine Works: Sodium Channels and Pain Signaling

The experience of pain originates when pain receptors (nociceptors) at the site of injury are triggered and these receptors send signals along peripheral nerves in the form the form of action potentials. These action potentials propagate signals through the nerves in the peripheral nervous system, or PNS, where they then enter the spinal cord and into the central nervous system, or CNS. In the dorsal horn of the spinal cord these pain signals are then propagated to several brain regions resulting in the perception of pain.

The propagation of nerve signals is driven by voltage-gated sodium channels, or NaVs. Following pain receptor stimulation, sodium channels in pain-sensing neurons open, allowing an influx of sodium ions which generates action potentials that are ultimately signaled to the brain. There are nine NaV subtypes distributed throughout the body with some of them them predominantly expressed in the CNS, while others are found in the heart or muscle.

Three NaV subtypes are predominantly expressed in the peripheral nociceptive neurons in the PNS:

1. NaV1.7 has been associated with certain neuropathies.
2. NaV1.8 has been associated with the transmission of nociceptive stimuli.
3. NaV1.9 has been associated with episodic pain syndromes.

 

Aside from concerns regarding loss or impairment of function after being injured, most people’s primary concern revolves around their pain and it’s effective management. This is especially true for patients who, prior to their acute injury, already suffer from chronic pain and belong to a population that research has shown to be hypersensitive to pain.

 

Management of pain in the days and weeks after an injury is important in itself. But it is also important because how well that acute pain is managed can impact the ultimate duration and severity of that pain. The goal of pain management is not “zero pain” but pain that is tolerable and allows the patient to function. What is most important to understand, however, is that the most significant, consistent factor contributing to the risk of progression of acute to chronic post-injury pain is the duration of severe acute post-injury pain which can lead to peripheral and central sensitization (See “Avoiding The Transition of Acute to Chronic Pain”).

Emphasis on Education

 

Accurate Clinic promotes patient education as the foundation of it’s medical care. In Dr. Ehlenberger’s integrative approach to patient care, including conventional and complementary and alternative medical (CAM) treatments, he may encourage or provide advice about the use of supplements. However, the specifics of choice of supplement, dosing and duration of treatment should be individualized through discussion with Dr. Ehlenberger. The following information and reference articles are presented to provide the reader with some of the latest research to facilitate evidence-based, informed decisions regarding the use of conventional as well as CAM treatments.

 

For medical-legal reasons, access to these links is limited to patients enrolled in an Accurate Clinic medical program.

 

Please note also, that many of the benefits for medications described on this web site include “off-label” use for a medication. Off-label prescribing refers to the use of medication for a condition not named in its FDA approval. Physicians are free to prescribe any medication they want, as long as there is some evidence for usefulness. And remember that the lack of an FDA indication does not necessarily mean lack of efficacy—it sometimes means that no drug company has deemed the investment in clinical trials worth the eventual pay off.

 

Should you wish more information regarding any of the subjects listed – or not listed –  here, please contact Dr. Ehlenberger. He has literally thousands of published articles to share on hundreds of topics associated with pain management, weight loss, nutrition, addiction recovery and emergency medicine. It would take years for you to read them, as it did him.
