NCT ID NCT07517068
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether acetazolamide, a drug already used for altitude sickness, can reduce inflammation and immune system activation caused by high altitude. Nineteen healthy adults will take either the drug or a placebo before and during a stay at 3800 meters. Researchers will measure changes in immune cells and inflammatory markers in the blood.

Active substance
Acetazolamide
What this could lead to
If successful, this could help explain how acetazolamide prevents altitude sickness and may point to new ways to control inflammation.

This is a very small, early-phase study (19 people) looking at blood markers, not symptoms. Results may not apply to the general public or lead to a treatment.
