In a patient on chronic hemodialysis, which beta‑blockers are recommended and how should the choice, dose, and timing be adjusted for reduced renal clearance and intradialytic hemodynamic shifts?

Beta-Blockers in Chronic Hemodialysis Patients

Primary Recommendation

For hemodialysis patients requiring beta-blocker therapy, carvedilol is the preferred agent for systolic heart failure based on proven mortality benefit, while cardioselective, moderately-to-highly dialyzable beta-blockers (bisoprolol, metoprolol) are reasonable alternatives for other cardiovascular indications, with timing of administration adjusted to avoid intradialytic complications. 1

Specific Beta-Blocker Selection

First-Line Choice for Heart Failure

• Carvedilol is the only beta-blocker with randomized trial evidence in dialysis patients with dilated cardiomyopathy, demonstrating improved left ventricular function, decreased hospitalization, and reduced cardiovascular and all-cause mortality comparable to the general population 1
• This recommendation is based on a single small randomized trial, but represents the strongest direct evidence available in this population 1

Alternative Agents Based on Dialyzability

• Nondialyzable beta-blockers (propranolol, carvedilol) may provide continuous intradialytic protection against arrhythmias but carry higher risk of intradialytic hypotension 1
• Highly dialyzable beta-blockers (atenolol, metoprolol) are associated with lower mortality risk in some retrospective studies but may result in subtherapeutic levels during dialysis sessions 1
• Bisoprolol was previously considered nondialyzable but recent evidence suggests it may be dialyzable, creating uncertainty about its classification 1

Specific Recommendations by Indication

• Hypertension: Atenolol showed reduced cardiovascular morbidity compared to lisinopril in predominantly Black hypertensive hemodialysis patients 1
• Chronic coronary artery disease: Beta-blockers should be used as in the general population, with dose adjustments for renal excretion 1
• Post-myocardial infarction: Beta-blockers are recommended based on general population data, though no dialysis-specific trials exist 1

Dosing Adjustments for Renal Clearance

Atenolol (Highly Dialyzable)

• Creatinine clearance 15-35 mL/min: Maximum 50 mg daily 2
• Creatinine clearance <15 mL/min or on hemodialysis: 25 mg daily 2
• Post-dialysis dosing: Give 25-50 mg after each dialysis session under hospital supervision due to risk of marked hypotension 2
• Atenolol accumulation occurs when creatinine clearance falls below 35 mL/min/1.73m² with significantly prolonged half-life (16-27 hours at CrCl 15-35, >27 hours at CrCl <15) 2

Bisoprolol (Dialyzability Uncertain)

• Initial dose in dialysis patients: 2.5 mg daily with cautious titration 3
• Drug replacement after dialysis is not necessary based on limited data suggesting bisoprolol is not dialyzable, though this is now questioned 3, 1

Carvedilol (Nondialyzable)

• No specific renal dose adjustment required as it is primarily hepatically metabolized 1
• However, higher risk of intradialytic hypotension compared to dialyzable agents like metoprolol 1

Timing of Administration

Key Principle

The timing of beta-blocker administration should be individualized based on intradialytic blood pressure patterns and drug dialyzability 1

Specific Strategies

• For nondialyzable agents (carvedilol, propranolol): Avoid administration before dialysis in patients with frequent intradialytic hypotension to prevent excessive hypotension during ultrafiltration 1
• For highly dialyzable agents (atenolol, metoprolol): Consider post-dialysis administration to maintain therapeutic levels and avoid removal during dialysis 1, 2
• For patients with stable intradialytic blood pressure: Once-daily, longer-acting formulations may improve adherence and reduce pill burden 1
• Nocturnal dosing should be considered to avoid interference with dialysis delivery and ultrafiltration 1

Critical Caveats and Pitfalls

Volume Status Considerations

• Beta-blockers are independently associated with fluid overload in hemodialysis patients (54.2% use in high-volume vs 19.2% in low-volume patients, p=0.01) 4
• Patients on beta-blockers experience more intradialytic muscle cramping (44.4% vs 12.5%, p=0.02), likely related to impaired fluid removal 4
• Volume management must be optimized first before initiating or uptitrating beta-blockers, as volume overload underlies most hypertension in dialysis 1

Intradialytic Hypotension Risk

• Avoid nondialyzable beta-blockers in patients with frequent intradialytic hypotension, as continuous beta-blockade during ultrafiltration increases hypotension risk 1
• The effectiveness of withholding beta-blockers before dialysis to reduce intradialytic hypotension remains unproven and is under investigation 1

Contraindications

• Sotalol is contraindicated in advanced kidney disease due to decreased clearance 1
• Beta-blockers should be avoided in patients with intradialytic hypotension associated with bradycardia, as bradycardia itself is linked to sudden cardiac death in this population 5

Monitoring Requirements

• Reassess target dry weight periodically, as beta-blockers may interfere with achieving euvolemia 1
• Monitor for bradycardia and hypotension, particularly during dialysis sessions 2, 6
• Special dosing regimens may be necessary to facilitate delivery of hemodialysis and ultrafiltration 1

Evidence Quality and Limitations

The evidence base for beta-blocker use in dialysis is limited by the lack of large randomized controlled trials 1, 7. The strongest evidence comes from a single small trial of carvedilol in dilated cardiomyopathy 1 and one trial of atenolol versus lisinopril in hypertension 1. Most other recommendations are extrapolated from the general population or based on observational data 8, 7, 5. The heterogeneity of the beta-blocker class and conflicting data on dialyzability make prescribing decisions challenging 1, 7.
