Administration of Tamsulosin to Reduce Orthostatic Hypotension Risk

Recommendations for Administration

  • Administering tamsulosin at bedtime is an effective strategy to reduce the risk of symptomatic orthostatic hypotension, as recommended by the American College of Cardiology 1
  • This approach is particularly important because blood pressure in the supine position tends to be higher in patients with orthostatic hypotension, according to the American Diabetes Association 2, 3
  • Nocturnal administration allows the patient to be in a supine position during the period when the medication reaches its maximum concentration, as suggested by the American College of Cardiology 1

Alternatives and Considerations

  • If orthostatic hypotension persists despite bedtime administration, consider reducing the dose or changing the treatment, as recommended by the American College of Cardiology 1
  • For patients with both hypertension and benign prostatic hyperplasia, consider alternative treatments like ACE inhibitors or ARBs, which have a minimal impact on orthostatic hypotension, according to the American College of Cardiology 1
  • Non-pharmacological measures such as increasing salt and water intake may be beneficial, as suggested by the European Society of Cardiology 4 and the European Association for the Study of Diabetes 5
