Dabigatran

Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026

Dabigatran is a direct thrombin (factor IIa) inhibitor that was the first DOAC approved for stroke prevention in non-valvular atrial fibrillation, based on the RE-LY trial. It is the only DOAC with a specific reversal agent (idarucizumab/Praxbind). Also approved for DVT/PE treatment after initial parenteral anticoagulation.

In short

What the research says.

A quick, data-only summary. The full evidence, dosing, and sources are below.

Dabigatran is a direct thrombin (factor IIa) inhibitor that was the first DOAC approved for stroke prevention in non-valvular atrial fibrillation, based on the RE-LY trial. NutriStack rates the supporting evidence as strong. Common adult dosing is AF: 150 mg twice daily (or 75 mg twice daily for CrCl 15–30 mL/min); DVT/PE: 150 mg twice daily after 5–10 days of parenteral anticoagulation (as prescribed by your physician), though a prescriber sets the actual dose. This profile indexes 10 sources.

What it's good for
  • Non-inferior (150 mg) or superior to warfarin for stroke prevention in AF1,2
  • Specific reversal agent available (idarucizumab/Praxbind)1,2
  • Fixed dosing without routine monitoring
  • Lower intracranial hemorrhage risk than warfarin8
What to watch for
  • Dyspepsia and GI discomfort (most common, ~10%)
  • Bleeding (major and minor)
  • GI bleeding (higher rate than warfarin at 150 mg dose)
  • Active pathological bleeding7
  • Mechanical prosthetic heart valve (RE-ALIGN trial terminated for excess events)

The bottom line

Evidence rating strong. Most-documented uses: non-inferior (150 mg) or superior to warfarin for stroke prevention in af, specific reversal agent available (idarucizumab/praxbind), fixed dosing without routine monitoring. 10 sources indexed (2014–2024), with 0 interaction records on file.

The science

How it works, mechanistically.

Core mechanism

Administered as the prodrug dabigatran etexilate, which is converted to active dabigatran by esterases. Dabigatran directly and reversibly inhibits both free and fibrin-bound thrombin (factor IIa). By inhibiting thrombin, it prevents conversion of fibrinogen to fibrin and inhibits thrombin-mediated platelet activation. Primarily renally eliminated (~80%).1,2
