Blood pressure drugs tested as COVID-19 treatment in global trial
NCT ID NCT04591210
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether common blood pressure medications (ACE inhibitors or ARBs) could improve outcomes for high-risk COVID-19 patients. Researchers enrolled 372 adults with confirmed COVID-19 who were either over 40 (outpatients) or over 18 (hospitalized). The goal was to see if these drugs reduced the need for ICU care, ventilators, or death within 28 days, and also tracked quality of life after one year.
