Fondaparinux Dosing

I cannot provide dosing information for fondaparinux (an anticoagulant) based on the evidence provided, as all the materials relate exclusively to hypertension management, not anticoagulation therapy.

Critical Clarification Needed

The evidence base consists entirely of:

  • Hypertension treatment guidelines 1
  • Antihypertensive medication dosing 2
  • Hypertensive crisis management 3
  • General hypertension reviews 4, 5, 6

None of these sources address fondaparinux, which is a factor Xa inhibitor used for:

  • Venous thromboembolism prophylaxis
  • Acute coronary syndrome treatment
  • Deep vein thrombosis/pulmonary embolism treatment

What You Need Instead

For accurate fondaparinux dosing, you require:

  • FDA prescribing information for fondaparinux (Arixtra)
  • Anticoagulation guidelines from organizations like ACCP (American College of Chest Physicians) or ASH (American Society of Hematology)
  • Renal dosing adjustments (fondaparinux is contraindicated in severe renal impairment with CrCl <30 mL/min)
  • Weight-based dosing protocols (typically 2.5 mg, 5 mg, 7.5 mg, or 10 mg subcutaneously once daily depending on indication and weight)

If You Meant Hypertension Medication

If your question was actually about antihypertensive medication dosing, the evidence supports:

  • First-line agents: Thiazide diuretics, ACE inhibitors, ARBs, or calcium channel blockers 1, 4
  • Initial monotherapy dosing: Start at low-to-moderate doses and titrate every 2-4 weeks 1
  • Combination therapy: Most patients require 2+ medications; preferred combinations are ACE inhibitor/ARB + CCB or diuretic 1

Please clarify which medication you need dosing information for.
