Clinical Trial: Prevention of High Altitude Pulmonary Edema

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: A Randomized Controlled Trial of the Effects of Tadalafil and Dexamethasone Versus Placebo on Pulmonary Edema Formation and Cerebral Blood Flow Autoregulation in High Altitude Newcomers With a Previou

Brief Summary:

A double-blind placebo controlled study

  • To compare the effect of tadalafil and dexamethasone versus placebo on Ppa and pulmonary edema formation in subjects susceptible to HAPE.
  • To investigate the effect of dexamethasone on alveolar fluid clearance, as assessed by measurement of the nasal potential difference, and prevention of HAPE.
  • To investigate the effect of the tadalafil and dexamethasone versus placebo on the dynamic CBF autoregulation properties and on the development of AMS in HAPE susceptible subjects.
