Abstract
INTRODUCTION: Acute mountain sickness is a common condition occurring in healthy subjects that undergo rapid ascent without prior acclimatization, as low as 2500 meters above sea level. The classic preventive agent has been acetazolamide, although in the last decade there has been evidence favoring ibuprofen. However, it is unclear which method is more efficient. METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis) and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified two systematic reviews that included only one primary study, which is a randomized trial. We concluded it is not possible to establish whether ibuprofen is better or worse than acetazolamide because the certainty of evidence has been evaluated as very low.
