Based on fibrinolytic activity demonstrated in multiple studies. Conservative estimate given limited direct circulation measurements. One RCT (n=153) showed clinical symptom improvement. Bleeding risk may increase with dose due to fibrinolytic mechanism.
Based on 8-week RCT showing dose-dependent increases of 22%, 51%, and 142% at 100, 300, and 1000mg respectively. Individual response varies significantly (30% show variable response). NR-SAFE trial confirmed safety up to 2000mg.
