This calculator helps determine the correct infusion rate for Amiodarone, a medication used to treat certain types of serious irregular heartbeats (arrhythmias). It's crucial to use the correct infusion rate to ensure therapeutic effectiveness while minimizing the risk of adverse effects.
Understanding Amiodarone Infusion Rates
Amiodarone is often administered as a loading dose followed by a maintenance dose. This calculator focuses on the initial loading dose infusion rate. The calculation ensures that the prescribed dose per kilogram of body weight is delivered over the specified infusion period.
