Landiolol is an ultra-short-acting, highly cardioselective β1-blocker developed primarily in Japan and increasingly studied worldwide for rapid rate control in atrial fibrillation (AF), especially in acute care settings.
Key Pharmacologic Properties:
-
Half-life: ~4 minutes, enabling rapid titration and withdrawal.
-
β1/β2 selectivity: ~255:1 (far higher than esmolol), minimizing bronchospasm and vasodilation.
-
Onset: Within minutes.
-
Clearance: Independent of hepatic or renal function.
Clinical Benefits:
-
Effective rate control in AF (especially postoperative, ICU, or hemodynamically unstable patients).
-
Minimal negative inotropic effect, making it safer in patients with impaired LV function compared to other beta-blockers.
-
Less hypotension than esmolol or diltiazem due to high β1 selectivity and absence of β2-mediated vasodilation.
-
Rapid titration allows tight control of HR without prolonged hemodynamic compromise.
Dosing:
-
Initiate without a bolus: e.g., 1–10 mcg/kg/min, titrate every 10–15 minutes.
-
Max doses vary by indication but typically up to 40 mcg/kg/min.
-
No loading dose is necessary, unlike esmolol.
Use in Sepsis and Critical Illness:
-
In septic patients with persistent tachycardia after adequate fluid resuscitation, landiolol has been studied for:
-
Reducing heart rate
-
Preserving or improving cardiac output
-
Avoiding hypotension seen with other beta-blockers
-
-
J-Land Study (2013) and subsequent European studies have shown:
-
Safe HR control in septic shock with no increased risk of hypotension or organ dysfunction
-
Improved diastolic filling, reduced myocardial oxygen demand, and possible anti-inflammatory effects
No benefit on controlling persistent sinus tachycardia in sepsis- more recent studies
-
Clinical Considerations:
-
Ideal for ICU patients with AF, particularly in postoperative cardiac surgery, sepsis, or HF with reduced ejection fraction.
-
Caution in patients with severe bradycardia, AV block, or profound shock.
-
Offers advantages over amiodarone (slower onset, QT prolongation, poor rate control) and diltiazem (vasodilation, hypotension).
When transitioning to oral beta-blockers:
1. Administer the oral beta-blocker
2. Ten minutes later, reduce the landiolol infusion rate by 50%
3. If satisfactory control is maintained for at least one hour, discontinue landiolol
Summary Statement:
Landiolol is an ultra-short-acting, β1-selective IV beta-blocker that provides rapid, titratable rate control in atrial fibrillation with minimal risk of hypotension or negative inotropy. Its excellent hemodynamic profile makes it suitable for use in critically ill patients, including those with sepsis and persistent tachycardia, where conventional beta-blockers may be poorly tolerated.
