Dabigatran Level (Pradaxa)

 
 
Clinical Information (ข้อมูลทางคลินิก):
Dabigatran, an oral direct thrombin inhibitor (DTI) that directly inhibits factor IIa, is indicated for use in patients with nonvalvular atrial fibrillation and venous thromboembolism. Dabigatran is administered orally twice daily, is eliminated primarily through the renal system, and can inhibit both soluble and clot-bound thrombin. Dabigatran does not require routine therapeutic monitoring. However, in selected clinical situations, measurement of drug level would be useful, eg, renal insufficiency, assessment of compliance, periprocedural, suspected overdose, advanced age, and extremes of body weight.
 
Reference Value (ค่าอ้างอิง):
1.  For stroke prevention in non-valvular atrial fibrillation
     -  Peak concentration: 117-275 ng/mL
     -  Trough concentration: 61-143 ng/mL

2.  For treatment PE/VTE
     -  Peak concentration: 117-275 ng/mL
     -  Trough concentration: 39-95 ng/mL
 
Interpretation (การแปลผล):
See Clinical Information for peak and trough drug concentrations observed in clinical trials of dabigatran.
