For an adult experiencing V Fib or pulseless V Tach, what is the initial dosage of Amiodarone?

The initial dosage of Amiodarone for an adult experiencing ventricular fibrillation (V Fib) or pulseless ventricular tachycardia (V Tach) is 300 mg administered intravenously or intraosseously. This dosage is consistent with advanced cardiac life support (ACLS) guidelines, which recommend 300 mg as a single bolus for these specific arrhythmias. The rationale behind this dosing is that Amiodarone is an antiarrhythmic medication used to stabilize heart rhythm, and the 300 mg dose is considered effective in achieving rapid drug concentration in critical scenarios, particularly when defibrillation is not successful. Following this initial dose, if necessary, an additional dose of 150 mg may be given later.
