Summary

This study looked at how the blood thinner rivaroxaban behaves in people with severe obesity and in those who had weight-loss surgery (gastric bypass or sleeve gastrectomy). Sixty-seven participants took rivaroxaban for 8 days, and researchers measured drug levels and clotting effects. The goal was to understand if obesity or surgery changes how the drug works, which can help doctors prescribe safer doses.
