Propranolol Dosing Guidelines

Introduction to Propranolol Dosing

• The American College of Cardiology recommends propranolol immediate-release at 80-160 mg daily in 2 divided doses for hypertension management 1
• High doses of propranolol (over 160 mg/day total) should be avoided in patients with decompensated cirrhosis, as they are associated with worse survival outcomes 2

Dosing Considerations

• Doses up to 160 mg/day total were associated with improved survival in decompensated cirrhosis 2
• Higher doses of propranolol increase the risk of bradycardia, hypotension, bronchospasm, and worsening heart failure 1, 3
• In cirrhotic patients, doses >160 mg/day are associated with worse survival, higher risk of hepatorenal syndrome, and severe circulatory dysfunction 2

Safety Monitoring

• The American College of Cardiology and other guideline societies recommend screening for second or third-degree heart block, decompensated heart failure, asthma/obstructive airway disease, and cardiogenic shock before propranolol treatment 4
• Ongoing monitoring should include assessment for bradycardia, hypotension, bronchospasm, worsening heart failure, and signs of circulatory dysfunction in cirrhotic patients 1, 2, 4

Contraindications and Precautions

• Propranolol should not be used in pre-excited atrial fibrillation, as it may precipitate very rapid ventricular rates 3
• In diabetic patients, propranolol masks hypoglycemia symptoms, and its use requires extreme caution 3, 4
