Acetazolamide reduces the erythropoietin response to hypoxia at high altitude in humans
Objective - Acetazolamide, a carbonic anhydrase inhibitor, is often used as a prophylactic drug for acute mountain sickness. It may interfere with erythropoietin production due to its action on ventilation and renal function. - Design - A randomized, double-blind, placebo-controlled trial with 2×250...

| 520 | |a Objective - Acetazolamide, a carbonic anhydrase inhibitor, is often used as a prophylactic drug for acute mountain sickness. It may interfere with erythropoietin production due to its action on ventilation and renal function. - Design - A randomized, double-blind, placebo-controlled trial with 2×250mg acetazolamide daily beginning one day before ascent from 590 m to 4559 m. - Setting - High-altitude research facilities at the Capanna Regina Margherita (Italy) at an altitude of 4559 m. - Participants - Eighteen healthy volunteers, aged 24-42 years. Main outcome measure: Plasma erythropoietin was measured by radioimmunoassay before and after the ascent. - Results - The increase of erythropoietin at high altitude was smaller in the acetazolamide group (increase by 10.8±7.8 U/L or 58%) than in the placebo group (increase by 22.7±13.8 U/L or 113%, p<.01). - Conclusion - Acetazolamide reduces the erythropoietin response to hypoxia in humans, which might also have therapeutic implications in conditions such as secondary polycythemia. | ||
