Amiodarone is primarily prescribed to treat irregular heart rhythms, specifically ventricular arrhythmias and atrial fibrillation when other antiarrhythmic drugs have proven ineffective. It helps restore and maintain a regular heart rhythm, reducing the risk of life-threatening cardiac arrhythmias.
Treatment Of Arrhythmias, Particularly When Other Drugs Are Ineffective Or Contra-indicated, Including Paroxysmal Supraventricular, Nodal, And Ventricular Tachycardias, Atrial Fibrillation And Flutter, Ventricular Fibrillation, And Tachyarrhythmias Associated With Wolff-Parkinson-white Syndrome:
Oral:
Adult: 200 Mg 3 Times A Day For 1 Week, Then Reduced To 200 Mg Twice Daily For A Further Week, Followed By Maintenance Dose, Usually 200mg Daily Or The Minimum Dose Required To Control Arrhythmia
Children 3-12 Yrs: Initially 5-10 Mg/kg (max 200 Mg) Twice Daily For 7-10 Days, Then Reduced To Maintenance Dose Of 5-10 Mg/kg Once Daily (max 200 Mg Daily); 12-18 Yrs: 200 Mg 3 Times Daily For 1 Wk Then 200 Mg Twice Daily For 1 Wk Then Usually 200mg Daily Adjusted According To Response.
By IV Infusion:
Adult: Initially 5 Mg/kg, To Be Given Over 20-120 Minutes With Ecg Monitoring, Subsequent Infusions Given If Necessary According To Response; Maximum 1.2 G Per Day

Ventricular Fibrillation Or Pulseless Ventricular Tachycardia Refractory To Defibrillation For Cardiopulmonary Resuscitation:
By IV Inj:
Adult: Initially 300 Mg, Dose To Be Considered After Administration Of Adrenaline, Dose Should Be Given From A Pre-filled Syringe Or Diluted In 20ml Glucose 5%, Then By IV Inj 150 Mg If Required, Followed By (by Iv Infusion) 900 Mg/24 Hours
