What class drug is Ibutilide?

What class drug is Ibutilide?

Ibutilide is a class III antiarrhythmic drug available only for intravenous use for the termination of atrial arrhythmias.

How do you administer Ibutilide?

Usual Adult Dose for Atrial Fibrillation Less than 60 kg: 0.01 mg/kg IV over 10 minutes; if arrhythmia persists 10 minutes after the end of the first infusion, repeat once. 60 kg or more: 1 mg IV over 10 minutes; if arrhythmia persists 10 minutes after the end of the first infusion, repeat once.

Why is Ibutilide given?

Ibutilide is an antiarrhythmic drug that was recently marketed for the rapid conversion of atrial fibrillation and atrial flutter. After intravenous administration, ibutilide is moderately effective in achieving prompt cardioversion to sinus rhythm, with greater efficacy in patients who have atrial flutter.

What is the mechanism of action of Ibutilide?

Ibutilide’s unique mechanism works by an activation of a specific inward sodium current, thus producing its therapeutic response in which a prolonged action potential increases myocytes’ cardiac refractoriness in case of atrial fibrillation and flutter.

What are the side effects of ibutilide?

Common side effects of ibutilide include:

• arrhythmia.
• headache.
• low blood pressure.
• nausea.
• palpitations (sensation that heart is pounding or racing)
• increased blood pressure.
• bradycardia (slow heart rate)
• tachycardia (fast heart rate)

Is ibutilide a potassium channel blocker?

Antiarrhythmic Drugs The third class consists of drugs that predominantly block the potassium channels. Dofetilide (18.3. 1) and ibutilide (18.3. 2) are pure potassium channel blockers.

What cardioversion means?

Cardioversion is a procedure used to return an abnormal heartbeat to a normal rhythm. This procedure is used when the heart is beating very fast or irregular. This is called an arrhythmia. Arrhythmias can cause problems such as fainting, stroke, heart attack, and even sudden cardiac death.

What is milrinone drip?

Milrinone is a vasodilator that works by relaxing the muscles in your blood vessels to help them dilate (widen). This lowers blood pressure and allows blood to flow more easily through your veins and arteries. Milrinone is used as a short-term treatment for life-threatening heart failure.

Does milrinone require a central line?

Adult Critical Care Protocol: May be administered by IV infusion by a nurse in Adult Critical Care. Each loading dose and infusion rate must be ordered by physician; nurses are not approved to titrate milrinone. Must be administered via central venous access device.

What are the side effects of Ibutilide?

What percentage of Cardioversions are successful?

The success rate of cardioversion with atrial fibrillation is generally better than 90 percent. Chances of success are lower when the atrial fibrillation has been present for more than several months or when the left atrium is very enlarged. In general, there are two ways that a cardioversion procedure for AF can fail.
