and FACTOR X. It is used for monitoring anticoagulant therapy with COUMARINS. (lookformedical.com)
It is being studied for various clinical indications and in some cases it offers an alternative to warfarin as the preferred orally administered anticoagulant ("blood thinner") since it does not require blood tests for international normalized ratio (INR) monitoring while offering similar results in terms of efficacy. (hemostasis.com)

However, all current anticoagulants like heparins, cumarins (Phenprocoumon/Marcumar®, Warfarin) as well as the latest direct-acting oral anticoagulants (Dabigatran/Pradaxa ® , Rivaroxaban/Xarelto ® , Apixaban/Eliquis ® , Edoxaban/Lixiana ® ) interfere substantially with the blood coagulation system resulting in a considerably elevated life-threatening bleeding risk. (zedira.com)

The second group of receptors reacts with small complement fragments (C4a, C3a, C5a) as well as with C1q, Ba, Bb and factor H. Stimulation of these receptors results in various biological effects (chemotaxis, secretion of vasoactive amines, mediators of the inflammatory and anaphylactic reaction etc. (dadamo.com)
