Introducing Journavx (Suzetrigine): A Breakthrough for Acute Pain
In early 2025, the U.S. Food and Drug Administration (FDA) approved Journavx (suzetrigine) for the treatment of moderate to severe acute pain in adults. This non-opioid oral tablet represents a major advancement in pain management, particularly for seniors who may be more susceptible to the risks of traditional opioids.
Understanding the Novel Mechanism of Action
Journavx utilizes its active ingredient, suzetrigine, to block Nav1.8 sodium channels in the peripheral nervous system, preventing pain signals from reaching the brain without affecting the central nervous system. This targeted action helps avoid central nervous system side effects common with opioids.
Comparison: Journavx vs. Traditional Medications
Journavx is a non-addictive option that targets peripheral sodium channels, distinguishing it from opioids and NSAIDs. Its mechanism is different from opioids, which act on central nervous system opioid receptors, and NSAIDs, which inhibit COX enzymes. Journavx avoids the high addiction risk, sedation, and respiratory depression associated with opioids and the potential for GI bleeding or cardiovascular risks seen with NSAIDs, especially in older adults. However, its current use is limited to acute pain.
| Feature | Journavx (Suzetrigine) | Opioids (e.g., Vicodin) | NSAIDs (e.g., Ibuprofen) |
|---|---|---|---|
| Mechanism | Blocks peripheral Nav1.8 sodium channels | Acts on central nervous system (CNS) opioid receptors | Inhibits cyclooxygenase (COX) enzymes, reducing inflammation |
| Addiction Risk | Non-addictive | High risk of misuse and addiction | No addiction risk |
| CNS Effects | No drowsiness, slowed breathing | Can cause sedation, respiratory depression | No direct CNS effects |
| GI Issues | Less frequent GI issues than opioids | Significant constipation is common | Can cause gastrointestinal bleeding and ulcers, especially in older adults |
| Cardiovascular Risk | No known risk reported in trials | Risks can vary by drug | Increases risk of heart attack and stroke in some populations |
| Approval | Acute, moderate to severe pain | Various pain levels, acute and chronic | Mild to moderate pain, inflammation |
Safety Considerations for Older Adults
Common side effects in clinical trials included itching, muscle spasms, increased creatine phosphokinase, and rash. Journavx should not be used by patients with severe kidney or liver disease, and caution is needed regarding drug interactions, particularly with strong CYP3A inhibitors. Avoiding grapefruit or grapefruit juice is also necessary. The medication is currently approved only for acute pain. It is important for seniors and their physicians to monitor for potential issues.
A Multimodal Approach: Combining Therapies
Effective pain management for seniors often involves combining medication like Journavx with non-pharmacological methods such as physical therapy, acupuncture, TENS, and cognitive behavioral therapy. This approach can improve outcomes and reduce reliance on medications.
The Future of Pain Management for Seniors
The FDA approval of Journavx marks a significant step in the development of safer pain relief options. Its success may encourage further research into similar Nav1.8 blockers and potential use for chronic pain.

Journavx provides a non-addictive option for acute pain, potentially offering a safer choice for many older adults. Seniors and their caregivers should discuss all available pain management strategies with a healthcare provider to determine the most suitable approach based on individual health needs and the type of pain.
