Landiolol interacts in the following cases:
NSAIDs may decrease the hypotensive effects of beta-blockers.
The effects of landiolol may be counteracted if concomitantly administered with sympathomimetic medicinal products having beta-adrenergic agonist activity. The dose of either agent may need to be adjusted based on patient response, or use of alternate therapeutic agents considered.
Concomitant administration of landiolol with tricyclic antidepressants, barbiturates, phenothiazines or antihypertensive agents may increase the blood pressure lowering effect. Administration of landiolol should be adjusted carefully to avoid unexpected hypotension.
Concomitant use of landiolol and insulin or oral antidiabetic medicinal products may affect the blood sugar lowering effect. Attention should be given to the blood sugar levels when these medicinal products are administered concomitantly, as beta-adrenergic blockade may mask signs of hypoglycaemia such as tachycardia.
Catecholamine-depleting agents or antisympathotonic agents (e.g. reserpine, clonidine, dexmedetomidine) may have an additive effect when concomitantly administered with landiolol. Patients treated concurrently with these agents should be closely monitored for evidence of hypotension or marked bradycardia.
Calcium antagonists such as dihydropyridine derivatives (e.g. nifedipine) may increase the risk of hypotension.
Concomitant use of clonidine and beta-blockers increase the risk of “rebound” hypertension. Although a rebound hypertensive effect was not observed after landiolol administration for 24 hours, such an effect cannot be excluded if landiolol is used in combination with clonidine.
Special caution must be taken when using floctafenine or amisulpride concomitantly with beta-blockers.
When heparin was administered intravenously during landiolol infusion in patients undergoing cardiovascular surgery, there was a 50% decrease in landiolol plasma levels in conjunction with a heparin induced decrease in blood pressure and an increase in landiolol circulation time. Heart rate values did not change in this situation.
The combination of landiolol with ganglion blocking agents can enhance the hypotensive effect.
The most frequently observed side effect is hypotension which is rapidly reversible with dosage reduction or discontinuation.
It is advised to continuously monitor the blood pressure and the ECG in all patients treated with landiolol.
Administration of landiololshould be titrated with caution when concomitantly used with verapamil, diltiazem, class I antiarrhythmic agents, amiodarone or digitalis preparations since co-administration can result in excessive suppression of cardiac function and/or atrioventricular conduction abnormalities.
Landiolol should not be used concomitantly with verapamil or diltiazem in patients with atrioventricular conduction abnormalities.
Beta-blockers should be avoided in patients with pre-excitation syndrome in combination with atrial fibrillation. In these patients beta-blockade of the atrioventricular node may increase the conduction through the accessory pathway and may precipitate ventricular fibrillation.
In patients with peripheral circulatory disorders (Raynaud’s disease or syndrome, intermittent claudication), beta-blockers should be used with great caution as aggravation of these disorders may occur.
Due to its negative effect on conduction time, beta-blockers should only be given with caution to patients with first degree heart block.
In patients with impaired left ventricular function (LEVF <40%, CI <2.5 L/min/m², NYHA 3-4) e.g. after cardiac surgery, during ischemia or in septic states, lower doses starting from 1 microgram/kg BW/min and increased in a stepwise fashion under close blood pressure monitoring up to 10 micrograms/kg BW/min have been used to achieve heart rate control.
Patients with bronchospastic disease should, in general, not receive beta-blockers. Because of the high relative beta-1 selectivity and titratability, landiolol can be used with caution in such patients. Landiolol should be carefully titrated to obtain the lowest possible effective dose. In the event of bronchospasm, the infusion should be terminated immediately and a beta-2 agonist should be administered, if necessary. If the patient already uses a beta-2 receptor-stimulating agent, it might be necessary to re-evaluate the dose of this agent.
Landiolol should be used with caution in diabetics or in case of hypoglycaemia. Hypoglycaemia is more severe with less cardio-selective beta-blockers. Beta-blockers can mask the prodromal symptoms of hypoglycaemia such as tachycardia. Dizziness and sweating, however, may not be affected.
In patients with cardiac insufficiency, concomitant treatment with beta-blocking agents may lead to cardiac failure. Careful titration of landiolol and appropriate hemodynamic monitoring is recommended.
Beta-blockers may increase the number and the duration of anginal attacks in patients with Prinzmetal’s angina due to unopposed alpha-receptor mediated coronary artery vasoconstriction. Non-selective betablockers should not be used for these patients and beta-1 selective blockers only with the utmost care.
There are no data from the use of landiolol in pregnant women available. Animal studies do not indicate clinically relevant effects with respect to reproductive toxicity. As a precautionary measure, it is preferable to avoid the use of landiolol during pregnancy.
Based on the pharmacological action of beta-blocking agents, in the later period of pregnancy, side effects on the foetus and neonate (especially hypoglycaemia, hypotension and bradycardia) should be taken into account. If the treatment with landiolol is considered necessary, the uteroplacental blood flow and foetal growth should be monitored. The newborn must be closely monitored.
It is unknown whether landiolol or its metabolites are excreted in human milk. Available pharmacokinetic data in animals have shown excretion of landiolol in milk. A risk to the suckling child cannot be excluded. A decision must be made whether to discontinue breastfeeding or to discontinue/abstain from landiolol therapy taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.
Landiolol was not shown to alter fertility in animal studies.
Not relevant.

Hypotension and bradycardia were the most common adverse events observed in landiolol treated patients. Hypotension was observed in 8.5% of 948 patients treated with landiolol in controlled clinical studies (vs. 2.1% treated with placebo, 8.5% with comparator treatment and 5.7% with no treatment) and in 8.6% of 581 patients in uncontrolled studies. Bradycardia was observed in 2.1% of 948 patients treated with landiolol in controlled clinical studies (vs. 0% treated with placebo, 2.5% with comparator treatment and 2.4% with no treatment) and in 0.5% of 581 patients in uncontrolled studies. In postmarketing treatment outcome studies/use surveys with landiolol, the adverse event frequency for hypotension and bradycardia was 0.8% and 0.7%, respectively (of 1,257 patients). All cases of hypotension and bradycardia related to landiolol treatment in the described studies resolved or improved, without any action being taken or within minutes after discontinuation of landiolol and/or additional treatment.
Serious adverse events based on clinical studies/postmarketing use surveys: Shock due to excessive hypotension was reported in one perioperative clinical trial patient with heavy bleeding (the event resolved 10 minutes after landiolol, prostaglandine and isoflurane discontinuation). Cardiac arrest, complete AV block, sinus arrest, and severe bradycardia reported from clinical trials and post-marketing surveillance for landiolol treatment were mainly associated with elderly patients or with patients having hypertension or cardiac diseases as complications.
Measures to be taken if these specific adverse reactions occur are described in section 4.2.
Laboratory parameters: Abnormal changes in laboratory values were reported in the context of adverse events but were also reported separately. In controlled studies abnormal changes in ALT, AST or bilirubin were reported in 5% of landiolol treated patients (n=241) and in 7% of the control group (n=243). The overall frequency of changes in laboratory parameters in these studies was 8.7% in landiolol treated patients and 13.6% in the control group. The changes in laboratory values were resolved or remitted and were not considered clinically relevant.
There are limited safety data for the use of landiolol in the elderly. Uncertainties regarding the safety profile of landiolol need to be considered, as adverse advents could also result from the use of co-medications or from the anaesthesia.
