Tiny nerve study could unlock secrets of blood pressure

NCT ID NCT03513770

First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 2 times

Summary

This early-stage study looks at how the body's nervous system controls blood pressure when veins are stretched. Researchers will use a blood pressure cuff to temporarily block blood flow in the arm and measure nerve activity in the leg, along with vein size using an MRI. They will also test whether a common painkiller (ketorolac) changes these responses. The study involves 18 healthy adults aged 21-35 and aims to better understand basic body functions, not to treat any disease.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
ketorolac tromethamine (an intravenous NSAID)
What this could lead to
If successful, this study could help scientists better understand how blood pressure is regulated, potentially pointing toward new treatments for conditions like fainting or low blood pressure.
What could go wrong
This is a very small, early-phase study with only 18 healthy volunteers, so results may not apply to patients with medical conditions. The intervention is short-term and not intended to treat any disease.
