Contraindications
RAPIBLYK is contraindicated in patients with:
- Severe sinus bradycardia, sick sinus syndrome, heart block greater than first degree.
- Decompensated heart failure.
- 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
Warnings
Hypotension
- Patients with hemodynamic compromise, hypovolemia, or on interacting medications are at increased risk of hypotension. Monitor blood pressure closely, especially if pretreatment blood pressure is low. Reduce or stop RAPIBLYK injection for hypotension then expect the blood pressure effect to wane within 30 minutes.
Bradycardia
- Patients with first-degree atrioventricular block, sinus node dysfunction, or conduction disorders are at increased risk of bradycardia, including sinus pause, heart block, severe bradycardia, and cardiac arrest. Monitor heart rate and rhythm in patients receiving RAPIBLYK injection. Reduce or stop RAPIBLYK injection for bradyarrhythmia.
Cardiac Failure
- Beta-blockers, like RAPIBLYK, can cause depression of myocardial contractility and may precipitate heart failure and cardiogenic shock. At the first sign or symptom of impending cardiac failure, stop RAPIBLYK injection and start supportive therapy.
Reactive Airways Disease
- Patients with reactive airways disease should, in general, not receive beta-blockers. Because of its relative beta-1 selectivity and titratability, RAPIBLYK injection may be titrated to the lowest possible effective dose. In the event of bronchospasm, stop the infusion immediately; a beta-2 stimulating agent may be administered with appropriate monitoring of ventricular rates.
Use in Patients with Diabetes Mellitus and Hypoglycemia
- Beta-blockers may prevent early warning signs of hypoglycemia, such as tachycardia, and increase the risk for severe or prolonged hypoglycemia at any time during treatment, especially in patients with diabetes mellitus, patients who are fasting (i.e., surgery, not eating regularly, or are vomiting), or children. Monitor for signs and symptoms of hypoglycemia in patients receiving RAPIBLYK.
Infusion Site Reactions
- Infusion site reactions such as pain, swelling and erythema have occurred with the use of RAPIBLYK injection. Avoid infusions into small veins or through a butterfly catheter. If a local infusion site reaction develops, use an alternative infusion site and avoid extravasation.
Use in Patients with Prinzmetal’s Angina
- Beta-blockers may exacerbate anginal attacks in patients with Prinzmetal’s angina because of unopposed alpha receptor–mediated coronary artery vasoconstriction.
Use in Patients with Pheochromocytoma
- If RAPIBLYK injection is used in the setting of pheochromocytoma, administer RAPIBLYK in combination with an alpha-blocker, and only after the alpha-blocker has been initiated. Administration of beta-blockers without opposing alpha blockade in the setting of pheochromocytoma has been associated with a paradoxical increase in blood pressure from the attenuation of beta receptor-mediated vasodilation in skeletal muscle.
Use in Patients with Peripheral Circulatory Disorders
- RAPIBLYK injection may exacerbate peripheral circulatory disorders, such as Raynaud’s disease or syndrome, and peripheral occlusive vascular disease.
Abrupt Discontinuation of RAPIBLYK Injection
- Severe exacerbations of angina, myocardial infarction, and ventricular arrhythmias have been reported in patients with coronary artery disease upon abrupt discontinuation of beta-blocker therapy. Observe patients for signs of myocardial ischemia when discontinuing RAPIBLYK injection.
Hyperkalemia
- Beta-blockers, including RAPIBLYK injection, can cause increases in serum potassium and hyperkalemia. The risk is increased in patients with risk factors such as renal impairment. Intravenous administration of beta-blockers has been reported to cause potentially life-threatening hyperkalemia in hemodialysis patients. Monitor serum electrolytes during therapy with RAPIBLYK injection.
Use in Patients with Metabolic Acidosis
- Beta-blockers have been reported to cause hyperkalemic renal tubular acidosis. Acidosis in general may be associated with reduced cardiac contractility.
Use in Patients with Hyperthyroidism
- Beta-adrenergic blockade may mask certain clinical signs (e.g., tachycardia) of hyperthyroidism. Abrupt withdrawal of beta blockade might precipitate thyroid storm; therefore, monitor patients for signs of thyrotoxicosis when withdrawing beta blocking therapy.
Use in Patients at Risk of Severe Acute Hypersensitivity Reactions
- When using beta-blockers, patients at risk of anaphylactic reactions may be more reactive to allergen exposure (accidental, diagnostic, or therapeutic).
- Patients using beta-blockers may be unresponsive to the usual doses of epinephrine used to treat anaphylactic or anaphylactoid reactions
Adverse Reactions
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.
- Landiolol injection was studied in 19 placebo-controlled clinical trials involving 1,761 patients (in a variety of clinical in-patient settings) with supraventricular tachycardia or at high risk for supraventricular tachycardia. The most important and common adverse reaction is hypotension, which occurred in 9.9% of patients receiving RAPIBLYK vs. 1% in those receiving placebo.
Postmarketing Experience
There is limited information regarding Landiolol Postmarketing Experience in the drug label.
Drug Interactions
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. Concomitant use of RAPIBLYK with negative inotropes or chronotropes may augment these effects.
Sympathomimetics, Positive Inotropes and Vasoconstrictors
- Beta adrenergic agonists will antagonize the effects of RAPIBLYK and may attenuate the heart rate lowering effects of RAPIBLYK. Positive inotropes and vasoconstrictors may attenuate the heart rate and blood pressure lowering effects of RAPIBLYK.
Catecholamine Depleting Drugs
- Observe patients treated with RAPIBLYK plus a catecholamine depletor (e.g., reserpine, monoamine oxidase inhibitors) for hypotension or marked bradycardia, which may cause vertigo, syncope, or postural hypotension.
- Catecholamine depleting drugs may have an additive effect when given with beta-blockers, which may increase the risk of hypotension or marked bradycardia related vertigo, syncope, or postural hypotension.
Use in Specific Populations
Pregnancy
Risk Summary
- The available published data on RAPIBLYK use in pregnant women are insufficient to inform a drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Landiolol exposure was limited to a single injection at the time of Cesarean delivery in a small clinical trial. Neonatal bradycardia, hypoglycemia, and respiratory depression have been observed with use of beta-blockers in pregnancy near the time of delivery (see Clinical Considerations). Administration of landiolol to pregnant rats showed distribution of landiolol to the placenta and the fetus. In animal reproduction studies, no embryo-fetal toxicity was observed in rats or rabbits during the period of organogenesis at landiolol exposure in rats approximately 2.7 times human exposure at the maximum recommended human dose (MRHD).
- The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
- Landiolol crosses the placenta in rats. Neonates born to mothers who are receiving landiolol during pregnancy, may be at risk for hypotension, hypoglycemia, bradycardia, and respiratory depression. Monitor neonates exposed to landiolol during pregnancy and labor for hypotension, hypoglycemia, bradycardia, and respiratory depression and manage accordingly.
Data
====Animal Data====
- Landiolol HCl was administered intravenously to pregnant rats (25, 50, or 100 mg/kg/day from gestation day 7 to 17) and rabbits (25, 50, or 100 mg/kg/day from gestation day 8 to 18). No adverse embryo-fetal effects were observed in rats at the landiolol HCl dose of 25 mg/kg/day, resulting in systemic landiolol exposure (AUC) of approximately 2.7-times the exposure at the MRHD. In rabbits, no adverse embryo-fetal effects were detected at the landiolol HCl dose of 100 mg/kg/day; the resulting systemic landiolol exposure (AUC) at this dose level was not determined.
- In a prenatal and postnatal development study in rats, landiolol HCl was administered intravenously at 25, 50, or 100 mg/kg/day from gestation day 17 to postpartum/lactation day 20. A decrease in the viability index for the offspring on postpartum day 4 was observed for the high dose group. No effect on pre/post-natal development was observed at 50 mg/kg dose, which represents landiolol exposures approximately 5.4 times the human exposure at the MRHD.
Pregnancy Category (AUS):
There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Landiolol in women who are pregnant.
Labor and Delivery
There is no FDA guidance on use of Landiolol during labor and delivery.
Nursing Mothers
Risk Summary
- There are no data on the presence of landiolol and its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. However, other drugs in this class are detected in human milk.
- Landiolol was present in the milk of lactating rats (see Data). When a drug is present in animal milk, it is likely that the drug will be present in human milk, but the concentration of landiolol in animal milk does not necessarily predict the concentration of drug in human milk.
- The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for RAPIBLYK and any potential adverse effects on the breast fed infant from RAPIBLYK or from the underlying maternal condition.
Clinical Considerations
====Monitoring for adverse reactions====
- Monitor the breastfed infant for bradycardia and other symptoms of beta blockade, such as lethargy (hypoglycemia).
Data
In a lactation study, administration of 14C-landiolol HCl administered as a single 1 mg/kg intravenous injection to lactating rats on postpartum/lactation day 13 to 14 was excreted in milk corresponding to approximately 70% of the concentration in plasma.
Pediatric Use
- The safety and effectiveness of RAPIBLYK injection in pediatric patients have not been established.
Geriatic Use
- Clinical studies of RAPIBLYK did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should usually start at the low end of the dosing range, reflecting greater frequency of decreased renal or cardiac function and of concomitant disease or other drug therapy.
Gender
There is no FDA guidance on the use of Landiolol with respect to specific gender populations.
Race
There is no FDA guidance on the use of Landiolol with respect to specific racial populations.
Renal Impairment
There is no FDA guidance on the use of Landiolol in patients with renal impairment.
Hepatic Impairment
- More conservative dose titration is recommended in patients with mild hepatic impairment (Child-Pugh A). The effect of moderate or severe hepatic impairment (Child-Pugh B or C) on landiolol pharmacokinetics is unknown.
- Avoid use of RAPIBLYK in patients with moderate or severe hepatic impairment (Child-Pugh B or C).
Females of Reproductive Potential and Males
There is no FDA guidance on the use of Landiolol in women of reproductive potentials and males.
Immunocompromised Patients

Overdosage
Signs and Symptoms of Overdose
- Overdoses of RAPIBLYK injection can cause adverse cardiac and central nervous system effects. These adverse effects may precipitate severe signs, symptoms, sequelae, and complications such as severe cardiac and respiratory failure, including shock and coma, and may be fatal. Continuous monitoring of the patient is required.
- Cardiac adverse effects include bradycardia, atrioventricular block (1-, 2-, 3-degree), junctional rhythms, intraventricular conduction delays, decreased cardiac contractility, hypotension, cardiac failure (including cardiogenic shock), cardiac arrest/asystole, and pulseless electrical activity.
- Central nervous system adverse effects include respiratory depression, seizures, sleep and mood disturbances, fatigue, lethargy, and coma.
- In addition, bronchospasm, hyperkalemia, and hypoglycemia (especially in children) may occur.
Treatment Recommendations
- Because of its approximately 4-minute elimination half-life, the first step in the management of toxicity should be to discontinue RAPIBLYK infusion. Then, based on the observed clinical effects, consider the following general measures:
Bradycardia
- Consider intravenous administration of atropine or another anticholinergic drug or cardiac pacing.
Cardiac Failure
- Consider intravenous administration of a diuretic or digitalis glycoside. In shock resulting from inadequate cardiac contractility, consider intravenous administration of dopamine, dobutamine, isoproterenol, milrinone or inamrinone.
Symptomatic Hypotension
- Consider intravenous administration of fluids or vasopressor agents such as dopamine or norepinephrine.
Bronchospasm
- Consider intravenous administration of a beta agonist or a theophylline derivative.
