Summary
This study tested whether inhaling tranexamic acid or terlipressin can quickly stop mild to severe coughing up blood (hemoptysis) without needing invasive procedures. 315 adults were randomly assigned to receive one of the two drugs or a placebo via nebulizer for 3 days. The goal was to see if these drugs could control bleeding within the first 3 days of hospitalization.
