Term
HMWK - High Molecular Weight Kininogen is what? Co-activates what?
Definition
Is a bradykinin precursor and co-activates Factor XII
Term
Kalikrein
Definition
In the presence of appropriate anionic surface and HMWK activates XII, generates bradykinin, activates plasminogen to plasmin, and pro-UPA to UPA.
Term
von Williebrand Factor
Definition
Adhesive platelet ligand that tethers platelet to exposed collagen at the sites of vascular injury (Primary hemostasis). Also a carrier protein for factor VII (secondary hemostasis).
Term
Used to assess the activity of K-dependent clotting factors (II,VII,IX,X). Shows the extent of Vitamin K depletion from Warfarin Therapy.
Definition
Prothrombin time (PT)
Term
[image]
Definition
Class: anticoagulant
MOA: Vitamin K epoxide reductase inhibitors (2)
Mechanism of action: inhibition of the redox cycling of vitamin K (by VKOR), which leads to decreased production of prothrombin & other clotting factors
Chemical class: coumarin
Second most common drug related ER visits
Assay Patients CYP2C9 and VKORC1 genotype
Term

Definition
UFH
Anticoagulant
CC: Polysaccharide
Negative sulfate group required for binding to antithrombin
Term
LMWH
Definition
LMWH
Smaller size translates to better selectivity for Xa and more favorable PK and PD properties
Term

Major DDIx problems with CYP2C19 Substrates/inhibitors
EX: PPI
Term

CC: 7 substituted 3,5 dihydroxyhepatanoic acid
Prodrug - very lipophilic and may have CNS effects
Hydroxyl very important
Term
