Timing of blood pressure medications and intradialytic hypotension

Area of Science:

• Nephrology
• Cardiovascular Medicine
• Clinical Pharmacology

Background:

• Intradialytic hypotension (IDH) is a frequent and severe complication of hemodialysis.
• IDH is linked to reduced quality of life, insufficient dialysis, vascular access issues, hypoperfusion, and increased mortality.
• Current guidelines suggest withholding antihypertensive medications before dialysis, a practice lacking strong evidence.

Discussion:

• This review examines the evidence linking blood pressure medication timing to IDH occurrence.
• It addresses clinical considerations for managing IDH in hemodialysis patients.
• The article critically evaluates the rationale behind current guideline recommendations.

Key Insights:

• Withholding antihypertensive medications before hemodialysis is not supported by robust evidence.
• Over half of dialysis patients may follow this unproven recommendation.
• The current practice may not be beneficial and could potentially be harmful.

Outlook:

• Further research is needed to establish optimal antihypertensive regimens for hemodialysis patients.
• Clinical practice guidelines for managing IDH should be re-evaluated based on available evidence.
• Individualized treatment strategies are crucial for managing blood pressure and IDH.
