Landiolol

Landiolol is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Landiolol rather than just read about it. In short: Landiolol, sold under the brand names Onoact, Rapibloc®, Sibboran® and Rapiblyk® among others, is a medication used for the treatment of supraventricular tachycardia, atrial fibrillation, and atrial flutter in perioperative, postoperative or other circumstances where short-term control of the ventricular rate with a short-acting agent is desirable.

Key takeaways

Landiolol belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Landiolol to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Landiolol from memory before moving on to harder problems.

Reference excerpt

Landiolol, sold under the brand names Onoact, Rapibloc®, Sibboran® and Rapiblyk® among others, is a medication used for the treatment of supraventricular tachycardia, atrial fibrillation, and atrial flutter in perioperative, postoperative or other circumstances where short-term control of the ventricular rate with a short-acting agent is desirable. With the exception of the USA, landiolol is also indicated for non-compensatory sinus tachycardia where, in the physician's judgment, the rapid heart rate requires specific intervention. It is a β-adrenergic blocker; an ultra short-acting, β1-super-selective intravenous adrenergic antagonist, which decreases the heart rate effectively with fewer negative effects on blood pressure or myocardial contractility. In comparison to other β blockers, landiolol has the shortest elimination half-life (3 to 4 minutes), ultra-rapid onset of effect (heart rate begins to decrease immediately after completion of administration), and predictable effectiveness with inactive metabolites (heart rate returns to baseline levels at 30 min after completion of landiolol hydrochloride administration). The pure S-enantiomerstructure of landiolol is believed to develop less hypotensive side effects in comparison to other β-blockers. This has a positive impact on the treatment of patients when reduction of heart rate without decrease in arterial blood pressure is desired. It is used as landiolol hydrochloride. Landiolol was approved for medical use in Japan in 2022, [10][11], Europe in 2016, Canada in November 2023, it has been approved in Bahrain, Kuwait, Qatar and Oman since October 2024, in the United States in November 2024 [12] and in Australia in June 2025.

Medical use Landiolol is indicated as an antiarrhythmic agent to treat

Supraventricular tachycardia and for the rapid control of ventricular rate in patients with atrial fibrillation or atrial flutter in perioperative, postoperative, or other circumstances where short-term control of the ventricular rate with a short acting agent is desirable. Non-compensatory sinus tachycardia where, in the physician's judgment the rapid heart rate requires specific intervention. Landiolol has been approved for the treatment of ventricular fibrillation or ventricular tachycardia in Japan. In the United States, since August 2026, landiolol is indicated not only for the short-term reduction of ventricular rate in adults with supraventricular tachycardia including atrial fibrillation and atrial flutter but also for pediatric patients with supraventricular tachycardia. Landiolol can be used as first-line treatment for acute ventricular rate control in patients with atrial fibrillation (Level I recommendation - 2024 ESC Guidelines for the management of atrial fibrillation developed in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS): Developed by the task force for the management of atrial fibrillation of the European Society of Cardiology (ESC), with the special contribution of the European Heart Rhythm Association (EHRA) of the ESC. Endorsed by the European Stroke Organisation (ESO)). The 2024 ESC Guidelines for the management of AF recommend that “in selected patients who are hemodynamically unstable or with severely impaired LVEF, intravenous amiodarone, landiolol, or digoxin can be used.” They further state that “The ultra-short acting and highly selective beta- blocker landiolol can safely control rapid AF in patients with low ejection fraction and acutely decompensated heart failure, with a limited impact on myocardial contractility or blood pressure”.

Worked examples

Example 1 — a first encounter with Landiolol

Start with the simplest possible case. Write down what Landiolol claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Landiolol before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Landiolol ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Landiolol

In research: Landiolol appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Landiolol in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Landiolol is common in secondary-school and first-year university syllabi. It links to neighbouring topics 4-Morpholinyl compounds, Antiarrhythmic agents, Beta blockers, so understanding it makes those chapters shorter.
In everyday life: Look for Landiolol outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Landiolol in simple terms?

Why does Landiolol matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
