is aspirin used to thin blood
To prevent them, doctors usually prescribe blood-thinning (anticoagulant) medications, such as low-molecular-weight heparin, which is given by injection, or the newer drug, rivaroxaban (brand name Xarelto), a pill. But that old medicine-cabinet standby, aspirin, also has blood-thinning properties. And the Canadian researchers wondered if this simple, inexpensive drug could also prevent blood clots after a major surgery. They compared the drugs for four weeks, following 10 days of treatment with heparin immediately post-surgery.
