Altitude Sickness Prevention and Efficacy of Comparative Treatments
Not Recruiting
Trial ID: NCT02604173
Purpose
This study is designed to be the first to examine the novel drug budesonide for prevention of
acute mountain sickness in comparison to acetazolamide and in the context of rapid ascent to
high altitude. The investigators will accomplish these objectives with a prospective, double
blinded view of a large population of hikers who are ascending at their own rate in a true
hiking environment.
