Comparison of Temazepam and Acetazolamide to Treat Difficulty Sleeping at High Altitude

Summary

More than 70% of visitors to high altitude suffer poor sleep. The present study seeks to answer the question: Which medication is associated with better sleep at high altitude: temazepam or acetazolamide? The investigators hypothesis is that one medication will be associated with higher subjective sleep scores than the other. The study will compare the sleep quality of 100 subjects as they take either temazepam or acetazolamide during a visit to high altitude.
