Brief Title

Drug Combination on Exercise Performance at High Altitude

Official Title

Enhancing Physical Performance and Mitigating Acute Mountain Sickness Via Pharmaceutical Intervention While at Altitude

Brief Summary

      This study is being conducted to determine the effectiveness of using two FDA approved
      medications in concert to reduce the likelihood of sickness due to low oxygen levels and to
      reduce the decrement in physical performance at higher elevations. The investigators
      hypothesize that this drug combination will reduce the symptoms of acute mountain sickness
      and improve exercise performance at high altitude compared to placebo.
