PREGNANCY-LACTATION-REPRODUCTION
- Use during pregnancy hasn't been adequately studied. Use cautiously during pregnancy if the patient benefits outweigh the fetal risk.
- Report pregnancies during therapy to BridgeBio at 1-844-550-2246.
- It isn't known whether this drug appears in human milk or how the drug affects milk production or infants who are breastfed. Weigh the benefit to the patient against the risk to the infant before use.
INTERACTIONS
Drug-drug. CYP2C9 substrates (diclofenac, phenytoin, tamoxifen, tolbutamide, warfarin): May increase substrate level. Monitor therapy more frequently.
UDP-glucuronosyltransferases and strong CYP3A inducers (glucocorticoids, rifampin, carbamazepine, phenobarbital, phenytoin): May decrease acoramidis level. Avoid use together.
ADVERSE REACTIONS
GI: diarrhea, upper abdominal pain.
GU: increased creatinine, decreased estimated GFR.
Reactions in bold italics are life-threatening.

Pharmaceutical company: AOP Orphan Pharmaceuticals
Pharmacologic classification: Beta blocker
Therapeutic classification: Antiarrhythmic
AVAILABLE FORMS
Powder for injection: 280 mg in a single-dose vial
INDICATIONS AND DOSAGES
Short-term reduction of ventricular rate in supraventricular tachycardia including atrial fibrillation and atrial flutter
Adults: Initially, 9 mcg/kg/minute continuous IV infusion. Adjust infusion rate every 10 minutes, as needed, for heart rate control in increments of 9 mcg/kg/minute. Maximum, 36 mcg/kg/minute dose.
Adjust-a-dose: For patients with impaired cardiac function, start at 1 mcg/kg/minute continuous IV infusion. Adjust infusion rate every 15 minutes, as needed, in increments of 1 mcg/kg/minute. Maximum, 36 mcg/kg/minute. Titrate cautiously in patients with Child-Pugh class A liver impairment. To transition to a PO beta-blocker, reduce the infusion rate by 50% 10 minutes after the PO dose. Discontinue landiolol if heart rate control is maintained for at least 1 hour.
CONTRAINDICATIONS AND CAUTIONS
- Contraindicated in patients hypersensitive to the drug or any of its components.
- Contraindicated in patients with severe sinus bradycardia, sick sinus syndrome, heart block greater than first degree, decompensated heart failure, cardiogenic shock, or pulmonary hypertension.
- This drug may depress myocardial contractility and precipitate heart failure and cardiogenic shock.
- Use cautiously in patients at risk for hypotension, including those with hemodynamic compromise or hypovolemia, or in those on interacting medications.
- Use cautiously in patients with first-degree AV block, sinus node dysfunction, or conduction disorders. This drug may increase the risk of bradycardia, including sinus pause, heart block, severe bradycardia, and cardiac arrest.
- Use cautiously in patients with reactive airway disease, diabetes, hypoglycemia, Prinzmetal angina, pheochromocytoma, and peripheral circulatory disorders.
- Use cautiously in patients with Child-Pugh class A liver impairment. Avoid use in Child-Pugh class B or C liver impairment.
- Use cautiously in patients with kidney impairment. This drug may cause hyperkalemia and hyperkalemic renal tubular acidosis.
- Patients at risk for anaphylactic reactions may be more reactive to allergen exposure and may be unresponsive to the usual doses of epinephrine used to treat anaphylactic reactions.
- Safety and effectiveness of this drug haven't been established in children.
- Dialyzable drug: Unknown.
- Overdose S&S: Bradycardia, AV block, junctional rhythms, intraventricular conduction delays, decreased cardiac contractility, hypotension, cardiac failure including cardiogenic shock, cardiac arrest, pulseless electrical activity, respiratory depression, seizures, sleep and mood disturbances, fatigue, lethargy, coma, bronchospasm, hyperkalemia, hypoglycemia.
PREGNANCY-LACTATION-REPRODUCTION
- Studies during pregnancy are inadequate. Avoid used during pregnancy.
- This drug crosses the placenta. Monitor neonates exposed to landiolol during pregnancy and labor for hypotension, hypoglycemia, bradycardia, and respiratory depression.
- It's unknown if this drug is excreted in human milk. Other beta-antagonists are detected in human milk. Monitor the breastfed infant for bradycardia and other symptoms of beta blockade, such as lethargy and hypoglycemia.
INTERACTIONS
Drug-drug. Catecholamine-depleting drugs (reserpine, MAO inhibitors): May have an additive effect when given with landiolol and increase the risk of hypotension, bradycardia-related vertigo, syncope, or postural hypotension. Avoid use together.
Negative inotropes and medications that slow heart rate or cardiac conduction (calcium channel blockers [verapamil], beta blockers): May increase risk of bradycardia or heart block. Avoid use together.
Positive inotropes, vasoconstrictors (digoxin, dobutamine): May decrease heart rate and blood pressure lowering effect of landiolol. Avoid use together.
Sympathomimetics (dopamine, epinephrine, isoproterenol): May decrease heart rate lowering effect of landiolol. Avoid use together.
ADVERSE REACTIONS
CV: hypotension, bradycardia.
