Hip Surgery Meds: Which Drug Works Best for Blood Clots?

A large clinical trial tested three medicines for preventing blood clots after knee or hip replacement surgery. The study included 18,883 patients who were randomly assigned to one of three groups. Each group took a different daily dose for 30 days. The main goal was to compare aspirin, warfarin, and rivaroxaban.

After six months, the results showed clear patterns. The aspirin group had the lowest rate of death or clot problems at 1.26 percent. The warfarin group had a slightly higher rate at 1.23 percent. The rivaroxaban group had the lowest rate at 0.94 percent. For safety, the rivaroxaban group also had the lowest risk of bleeding or other serious issues at 3.48 percent. Warfarin showed the highest safety risk at 3.36 percent.

The researchers also checked how well patients followed their treatment plans. When they looked at all participants, the results stayed the same. This means the findings are strong and reliable. The small differences between the drugs might not be important for most people. More studies are needed to decide which medicine is best for everyday use.
