Predict how a medication that inhibits the active enzyme factor Xa from being activated would impact the coagulation cascade
What will be an ideal response?
The end result of both the intrinsic and extrinsic pathways is the same: activation of factor X to the active enzyme factor Xa. In the common pathway, factors Xa and Va along with calcium ions form prothrombin activator. Prothrombin activator converts the inactive prothrombin into the active enzyme thrombin. Thrombin turns fibrinogen into fibrin, which forms the mesh that glues together the platelet plug. Without factor Xa, this common pathway would not be able to proceed and fibrin would not be produced. The coagulation cascade would not be able to complete without factor Xa.
