Heparin News and Research

RSS

Heparin, a highly-sulfated glycosaminoglycan, is widely used as an injectable anticoagulant, and has the highest negative charge density of any known biological molecule. It can also be used to form an inner anticoagulant surface on various experimental and medical devices such as test tubes and renal dialysis machines. Pharmaceutical grade heparin is derived from mucosal tissues of slaughtered meat animals such as porcine (pig) intestine or bovine (cow) lung.

Isis commences ISIS-FXIRx Phase 1 study for treatment of clotting disorders

Isis Pharmaceuticals, Inc. announced the initiation of a Phase 1 study of ISIS-FXIRx, an antisense drug designed to treat clotting disorders. ISIS-FXIRx inhibits the production of Factor XI, a clotting factor that is an important component of the coagulation pathway. Because of its role in the intrinsic coagulation pathway, inhibition of Factor XI could offer an effective approach for preventing the formation of blood clots with a lower risk of bleeding.
