Clexane: The evidence base for Target Range is poor, but the consensus for PROPHYLAXIS is 0.1-0.4 U/mL, and for TREATMENT is 0.6-1.0 U/mL (the latter applies to bd dosing; a higher target range may be appropriate for daily dosing).
Rivaroxaban: There is no established therapeutic range for Rivaroxaban (Xarelto). Plasma Rivaroxaban concentration drops after dose administration and the assay result has to be interpreted in the context of the last doses. Note that routine Rivaroxaban monitoring is not recommended and the levels should not be used for tailoring doses.
ASTH (2013) recommends the following mean peak and trough levels for 20mg once daily (od):
|20mg od||170-400 ug/L||1-150 ug/L|
FXA - Clexane, FXAR - Rivaroxaban
