Can a common mineral ease brain swelling after trauma?
NCT ID NCT07763665
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial tests whether giving magnesium sulfate soon after a moderate traumatic brain injury can reduce harmful inflammation in the brain. Adults aged 18–60 with a moderate head injury will receive either magnesium sulfate or a saltwater placebo within 8 hours of injury. Researchers will measure changes in a key inflammatory marker (NLRP3) and track patients' recovery and safety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Magnesium sulfate (MgSO4) given intravenously, compared with normal saline (placebo).
- What this could lead to
- If effective, magnesium sulfate could become a simple, widely available anti-inflammatory treatment to improve recovery after moderate traumatic brain injury.
- What could go wrong
- This is a small, early-phase trial (64 patients) measuring a biomarker, not long-term outcomes. Magnesium can cause side effects like low blood pressure or toxicity, and results may not generalize.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Male and female patients aged 18 to 60 years. 2. Sustained a closed head trauma with the study drug infusion initiated within 8 hours of the injury. 3. TBI confirmed by history and clinical examination. 4. Patients with moderate (GCS = 9-12) traumatic brain injury. 5. Evidence of TBI confirmed by abnormalities consistent with trauma on CT scan upon admission (diffuse injury II-IV, evacuated and non-evacuated mass lesion, Marshall's CT Classification ). 6. Hemodynamic stability at the time of enrollment. Exclusion Criteria: 1. Patient Refusal 2. Prolonged and/or uncorrectable hypoxia (PaO₂ \< 60 mmHg) or persistent hypotension (systolic blood pressure \< 90 mmHg) at the time of randomization. 3. Cardiopulmonary arrest. 4. Concomitant spinal cord injury. 5. Pregnant or lactating females. 6. Penetrating head injury. 7. Associated other extra-cranial trauma or systemic polytrauma. 8. Undergoing surgical interventions during the study. 9. Pre-existing severe cardiac arrhythmia, heart block, or significant myocardial damage (documented on ECG). 10. Known history of chronic renal failure or abnormal baseline renal function. 11. Known hypersensitivity or allergic reaction to magnesium sulfate. 12. Patients on chronic steroid therapy. 13. BMI\>35 kg/m2. \-
