Very surprised to see this on BBC news today. Though the potential side effects of Amiodarone are bad it's still the most effective anti-arrhythmic drug as far as I know. Maybe this consultation is also taking side effects into account (I couldn't find out further since Googling didn't pull up the actual NHS announcement).
I'm assuming there won't be a total ban on Amiodarone since some people can't take the other anti-arrhythmics because of issues such as abnormal heart structure.
I imagine it won't be the "go to" of choice any more but will still be available, NHS England will probably direct prescribers to cheaper alternatives and there will need to be masses of red tape cut and hoops jumped through for them to justify prescribing it to someone.
I remember years ago Dronedrone being "red flag" medication and only available through the hospital and even then it was non-formulary so took ages to dispense.
For about ten years, European Society of Cardiology protocol is tha Amiodarone should be the drug of last resort so this must surely just be emphasising . that.
