Overview
11 DESCRIPTION RAPIBLYK (landiolol) for injection is a beta-1 adrenergic receptor blocker with a very short duration of action (elimination half-life is approximately 4 minutes). Landiolol is: [(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]methyl 3-[4-[(2S)-2-hydroxy-3-[2-(morpholine-4-carbonylamino)ethylamino]propoxy]phenyl]propionate and has the following structure: The active pharmaceutical ingredient...
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action RAPIBLYK is a selective beta-1-adrenoreceptor antagonist that inhibits the positive chronotropic effects of the catecholamines, epinephrine and norepinephrine, on the heart, where beta-1-receptors are predominantly located. Landiolol does not exhibit any membrane-stabilizing activity or intrinsic sympathomimetic activity at the approved recommend dosage in vitro. 12.2 Pharmacodynamics Landiolol exposure-response relationships and the time course of pharmacodynamic response are not fully characterized. 12.3 Pharmacokinetics Landiolol peak plasma concentration (C max ) over the approved dosage range in healthy adult volunteers, patients with atrial fibrillation or atrial flutter and pediatric patients with supraventricular tachycardia is...
Indications
- 1 INDICATIONS AND USAGE RAPIBLYK is indicated for the short-term reduction of ventricular rate in adults with supraventricular tachycardia including atrial fibrillation and atrial flutter, and pediatric patients with supraventricular tachycardia. RAPIBLYK is a beta adrenergic blocker indicated for the short-term reduction of ventricular rate in: adults with supraventricular tachycardia including atrial fibrillation and atrial flutter ( 1 ), and pediatric patients with supraventricular tachycardia.( 1 )

Dosage
2 DOSAGE AND ADMINISTRATION Administer as an intravenous infusion in a monitored setting. ( 2.1 ) Titrate according to ventricular rate. ( 2.1 ) If normal cardiac function, start at 9 mcg/kg/min; adjust dose in 10-minute intervals as needed in increments of 9 mcg/kg/min to a maximum of 36 mcg/kg/min. ( 2.1 ) If impaired cardiac function, start at 1 mcg/kg/min; adjust dose in 15-minute intervals as needed in increments of 1 mcg/kg/min to a maximum of 36 mcg/kg/min. ( 2.1 ). 2.
Contraindications
- 4 CONTRAINDICATIONS RAPIBLYK is contraindicated in patients with: Severe sinus bradycardia, sick sinus syndrome, heart block greater than first degree [see Warnings and Precautions ( 5.2 )] . Decompensated heart failure [see Warnings and Precautions ( 5.3 )] . Cardiogenic shock: May precipitate further cardiovascular collapse and cause cardiac arrest. Pulmonary hypertension: May precipitate cardiorespiratory decompensation. Hypersensitivity reactions, including anaphylaxis, to landiolol or any of the inactive ingredients 5.
Side Effects
- 6 ADVERSE REACTIONS The most common adverse reaction (9.9%) is hypotension ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact AOP Orphan Pharmaceuticals at drugsafety.us@aop-health.com or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Interactions
- 7 DRUG INTERACTIONS Negative Inotropes and Chronotropes: Avoid ( 7.1 ) Sympathomimetics, Positive Inotropes and Vasoconstrictors: Avoid ( 7.2 ) Catecholamine Depleting Drugs: Monitor blood pressure and heart rate ( 7.3 ). 7.1 Negative Inotropes and Chronotropes Avoid concomitant use of RAPIBLYK with negative inotropes and medications that slow heart rate or cardiac conduction. Beta-blockers, like RAPIBLYK, can cause depression of myocardial contractility and increase the risk of bradycardia or heart block.
