Amiodarone maintenance infusion details include which of the following?

Amiodarone IV maintenance dosing uses a higher-rate infusion for the first period after loading, then lowers the rate to minimize toxicity while maintaining effect. The standard approach is to run 1 mg per minute for the first 6 hours, using a solution of 150 mg in 100 mL of normal saline. After those 6 hours, the rate is typically reduced to 0.5 mg per minute. This aligns with the goal of delivering a sufficient antiarrhythmic effect quickly during the initial phase, then tapering to a safer, lower maintenance rate. Options that suggest a faster rate (2 mg/min) or a shorter initial period (1 mg/min for 2 hours) don’t provide the correct 6-hour high-rate window. A maintenance rate of 0.5 mg/min is used after the initial 6 hours, not during it.
