Amiodarone Injection (Amiodarone Hydrochloride) - Summary



Amiodarone hydrochloride injection is a class III antiarrhythmic drug.

Amiodarone HCl injection is indicated for initiation of treatment and prophylaxis of frequently recurring ventricular fibrillation and hemodynamically unstable ventricular tachycardia in patients refractory to other therapy. Amiodarone injection also can be used to treat patients with VT/VF for whom oral amiodarone is indicated, but who are unable to take oral medication. During or after treatment with intravenous amiodarone injection patients may be transferred to oral amiodarone therapy (see DOSAGE AND ADMINISTRATION).

Amiodarone injection should be used for acute treatment until the patient's ventricular arrhythmias are stabilized. Most patients will require this therapy for 48 to 96 hours, but amiodarone injection may be safely administered for longer periods if necessary.

Pharmacokinetics of intravenous amiodarone and its electrocardiographic effects on healthy Japanese subjects. [2011.05]
The aim of this phase I, dose-escalating study was to evaluate the pharmacokinetics, electrocardiographic effect and safety of amiodarone after a single intravenous administration in Japanese subjects. Thirty-two healthy Japanese male volunteers (20-32 years) were randomized to three single-dose groups (1.25, 2.5 and 5.0 mg/kg)...

A randomized active-controlled study comparing the efficacy and safety of vernakalant to amiodarone in recent-onset atrial fibrillation. [2011.01.18]
OBJECTIVES: This randomized double-blind study compared the efficacy and safety of intravenous vernakalant and amiodarone for the acute conversion of recent-onset atrial fibrillation (AF). BACKGROUND: Intravenous vernakalant has effectively converted recent-onset AF and was well tolerated in placebo-controlled studies... CONCLUSIONS: Vernakalant demonstrated efficacy superior to amiodarone for acute conversion of recent-onset AF. Both vernakalant and amiodarone were safe and well tolerated in this study.

Clinical Trials Related to Amiodarone Injection (Amiodarone)

Minocycline Plus Amiodarone Versus Amiodarone Alone for the Prevention of Atrial Fibrillation After Cardiac Surgery [Active, not recruiting]
Postoperative atrial fibrillation (POAF) is a common complication after heart surgery. Amiodarone is the drug of choice to treat POAF. Inflammation is considered one of underlying factor for POAF. Minocycline is an antibiotic with anti-inflammatory properties.

Catheter Ablation Versus Amiodarone for Shock Prophylaxis in Defibrillator Patients With Ventricular Tachycardia [Terminated]
Implantable Cardioverter Defibrillators (ICDs) provide a shock or pacing therapy to bring back a normal heart beat when a patient experiences a dangerous abnormal heart rhythm such as ventricular tachycardia (VT). ICDs are very successful in bringing back a normal heart beat when VT occurs, but they do not prevent further dangerous heart rhythms from occurring. This study is designed to determine the best way to manage patients who have an ICD and who continue to have episodes of VT. There are two methods for treatment the VT: 1) Ablation, and 2) Medication. An ablation procedure involves placing a flexible catheter (insulated wire) in the groin area and threading it into the heart. After the doctor has located the affected area responsible for the VT, radiofrequency energy is delivered by the power generator through the catheter to the inside of the heart. The radiofrequency energy ablates (burns) a small area of the heart tissue thought to cause the VT. A medication called Amiodarone is an "anti-arrhythmic" prescribed to prevent abnormal heart rhythms from recurring. The purpose of this study is to compare these two different methods for treating VT. Treatment with ablation and amiodarone are both considered the standard of care for patients with VT but they have not been compared directly in a study like this before.

Withdrawal Versus Continuation of Amiodarone in Successfully Treated Patients With Persistent Atrial Fibrillation [Completed]
Amiodarone is considered to be the most effective antiarrhythmic drug in the prevention of persistent atrial fibrillation. It can however cause many adverse events, both cardiac and non-cardiac. Long-term maintenance of sinus rhythm after cardioversion is difficult especially because of high recurrence rates during the first month after cardioversion. Duration of atrial fibrillation, type of underlying disease, left ventricular function, left atrial size and age are associated with maintaining sinus rhythm. Early recurrence of atrial fibrillation may be related to a highly arrhythmogenic period due to recovery from electrical remodelling. Late recurrences may be related to other triggers than recovery from electrical remodelling. In this study the investigators want to investigate the effect of amiodarone withdrawal on the occurrence of late relapses of persistent atrial fibrillation. Furthermore, the investigators want to investigate the effect of amiodarone withdrawal on the occurrence of amiodarone related adverse events as well as adverse events related to atrial fibrillation or underlying heart disease. The investigators also want to investigate which patients characteristics are and potential triggers have a prognostic value in the occurence of late relapses after amiodarone withdrawal.

Amiodarone for the Prevention of Reperfusion Ventricular Fibrillation [Completed]
This was a prospective, randomized, double blinded study in which patients undergoing a cardiopulmonary bypass (CPB) with aortic cross clamping were randomly assigned to receive amiodarone, lidocaine, or saline placebo prior to removal of the aortic cross clamp. (CPB is a technique that temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the body.) Specifically, we will test the hypothesis that amiodarone is superior to both lidocaine and placebo in the prevention of a severely abnormal heart rhythm when the blood flow is restored to the heart after the aortic cross clamp is removed.

Safety and Efficacy of Oral Versus Intravenous Amiodarone in the Treatment of AF [Not yet recruiting]
Atrial fibrillation (AF) remains a significant contributor to cardiovascular morbidity. Amiodarone is a potent antiarrhythmic drug; however, patients receiving IV amiodarone are at high risk for phlebitis. Phlebitis may lead to infection, additional medical intervention, delay in treatment, and prolonged hospitalization. Therefore, examining new therapy approach, aimed to reduce the incidence of phlebitis is a valuable clinical and research goal. Aim: To evaluate the safety and efficacy of oral versus intravenous (IV) Amiodarone in the treatment of AF of recent onset (duration < 48 h).
