What is the onset time of Amiodarone?

Amiodarone is known for its relatively slow onset of action when used for the treatment of arrhythmias, particularly when administered intravenously. Generally, the onset of therapeutic effects can vary depending on the route of administration, but when considering intravenous delivery, the effects may be noted within minutes. However, when used in oral form, the onset time can be much longer, as the drug accumulates in body tissues. It is essential to understand that while Amiodarone might have a rapid onset after IV administration, its effects on cardiac rhythm may not be immediately evident, as it has a long half-life and extensive tissue distribution.

Considering that the onset is not categorized as rapid, moderate, or prolonged under typical circumstances of administration and context, the classification of onset time as slow captures the essence of how one might expect its effects to materialize in a clinical setting.
