⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⛔ 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
5.3Severe sinus bradycardia ( 4 ) Sick sinus syndrome ( 4 ) Heart block greater than first degree ( 4 ) Decompensated heart failure ( 4 ) Cardiogenic shock ( 4 ) Pulmonary hypertension ( 4 ) Known hypersensitivity to landiolol ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Risk of hypotension, bradycardia, and cardiac failure: Monitor for signs and symptoms of cardiovascular adverse effects. Reduce or discontinue use ( 5.1 , 5.2 , 5.3 ) Risk of exacerbating reactive airway disease ( 5.5 ) Diabetes mellitus: May mask symptoms of hypoglycemia and alter glucose levels; monitor ( 5.6 ) Monitor for signs of myocardial ischemia when abruptly discontinuing in patients with coronary artery disease ( 5.10 )
5.1Hypotension 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.
5.2Bradycardia 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.
5.3Cardiac 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 [see Overdosage ( 10 )] .
5.4Reactive 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.
5.5Use 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 pediatric patients. Monitor for signs and symptoms of hypoglycemia in patients receiving RAPIBLYK.
5.6Infusion 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.
5.7Use 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.
5.8Use 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.
5.9Use 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.
5.10Abrupt 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.
5.11Hyperkalemia Beta-blockers, including RAPIBLYK injection, can cause increases in serum potassium and hyperkalemia. The risk is increased in patients with risk fa…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most common adverse reaction (9.9%) is hypotension ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact AOP Orphan Pharmaceuticals at [email protected] or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical 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. The safety of RAPIBLYK was evaluated in 19 placebo-controlled clinical trials involving 1,761 adult patients (in a variety of clinical in-patient settings) with supraventricular tachycardia or at high risk for supraventricular tachycardia.
The most common adverse reaction is hypotension, which occurred in 9.9% of patients receiving RAPIBLYK vs. 1% in those receiving placebo [see Warnings and Precautions ( 5.1 )]. In a single-arm, unblinded clinical trial in 60 pediatric patients who received RAPIBLYK, the most common adverse reaction was hypotension, which occurred in 10% of patients aged birth to <18 years receiving RAPIBLYK [see Warnings and Precautions ( 5.1 )].
Hypotension was also the most common adverse reaction leading to treatment discontinuation.
🔄 Drug 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 ).
7.1Negative 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 [see Warnings and Precautions ( 5.2 )( 5.3 )] .
7.2Sympathomimetics, 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.
7.3Catecholamine 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 [see Warnings and Precautions ( 5.1 )] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy 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) (see Data) . 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.
8.2Lactation 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 14 C-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 ▾
8.4Pediatric Use The safety and effectiveness of RAPIBLYK for the short-term reduction of ventricular rate in supraventricular tachycardia have been established in pediatric patients. Use of RAPIBLYK is supported by evidence from adequate and well-controlled studies in adults, with additional pharmacokinetic, pharmacodynamic and safety data from a descriptive single-arm, unblinded study that enrolled 60 pediatric patients from birth to <18 years of age. In this study, treatment with RAPIBLYK resulted in a >20% reduction in ventricular rate from baseline in patients with atrioventricular reentrant tachycardia (6/7, 85.7%), focal atrial tachycardia (4/8, 50%), junctional ectopic tachycardia (3/12, 25%), and in inappropriate sinus tachycardia (10/30, 33.3%) [see Clinical Pharmacology ( 12.3 )].
🧓 Geriatric Use ▾
8.5Geriatric 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.
🆘 Overdosage ▾
10 OVERDOSAGE
10.1Signs 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 pediatric patients) may occur.
10.2Treatment 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.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism 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.
12.2Pharmacodynamics Landiolol exposure-response relationships and the time course of pharmacodynamic response are not fully characterized.
12.3Pharmacokinetics 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 provided in Table 3. Table 3: Landiolol peak plasma concentration (Cmax) in healthy volunteers and patients with atrial fibrillation or atrial flutter. Landiolol Dosage Peak Plasma Concentration (C max ) Healthy Adult Volunteers (mean) a Adult Patients with Atrial Fibrillation or Atrial Flutter (range) Pediatric Patients with Supraventricular Tachycardia (range) 9.3 mcg/kg/min 0.2 mcg/mL Not studied Not available 18.6 mcg/kg/min 0.5 mcg/mL Not studied Not available 37.3 mcg/kg/min 1.0 mcg/mL 0.52 to 1.77 mcg/mL 0.52 to 4.71 mcg/mL a 2 hour infusion 9.3 mcg/kg/min landiolol is equivalent to 10 mcg/kg/min landiolol hydrochloride.
Landiolol pharmacokinetics increases dose-proportionally in the dosage range of 9.3 to 74.6 mcg/kg/min (2 times the maximum approved recommended dosage). Landiolol reached steady-state values approximately 15 minutes after initiation of the infusion. Distribution Landiolol steady state volume of distribution is
0.4L/kg. Landiolol protein binding is <10%. Elimination Landiolol elimination half-life is 4.5 minutes at steady state.
Total body clearance of landiolol is 57 mL/kg/min following a 20-hour continuous landiolol infusion of 37.3 mcg/kg/min. Metabolism Landiolol is primarily metabolized by pseudocholinesterases and carboxylesterases in the plasma to the active metabolite M1. M1 has less than 1/40 th of the pharmacological activity of landiolol.
M1 AUC 0-inf is approximately 12 times greater than landiolol. Excretion Approximately 50 to 75% of the landiolol administered dose (approximately half of this as metabolite M1, and 8% as parent) is recovered in urine at 4 hours and 89 to 99% at 24 hours following a 60 min intravenous infusion. Specific Populations The effect of age and renal impairment on landiolol pharmacokinetics is unknown.
Patients with hepatic impairment Landiolol geometric mean AUC increased by 44% and C max by 42% in 5 patients with mild hepatic impairment (Child-Pugh A) and 1 patient with moderate hepatic impairment (Child-Pugh B). The effect of moderate hepatic impairment (Child-Pugh B) on landiolol pharmacokinetics has not been fully characterized and the effect of severe hepatic impairment (Child-Pugh C) is unknown. Drug Interaction Studies In Vitro Studies CYP 450 enzymes : Landiolol and the metabolite M1 are time-dependent CYP 2D6 inhibitors at exposures approximately 50 times the human exposure at the MRHD, but do not inhibit CYP 1A2, 2C9, 2C19, or 3A4.
