low molecular weight heparin

Abbreviation: LMWH
The most bioavailable fraction of heparin. It has a more precise anticoagulant effect than unfractionated heparins and is used to prevent and treat deep venous thrombosis, pulmonary embolism, and acute coronary syndromes.

CAUTION!

It should be used selectively, if at all, in patients with reduced kidney function.
