Dosage Forms and Strengths. Total initial dosage during first 24 hours is approximately 1000 mg. Only a secondary care specialist will initiate loading with amiodarone (by oral or intravenous route depending upon the clinical situation and indication) Loading dose (by mouth): 200mg three times daily for one week, reduced to 200mg twice daily for a further week, followed by a maintenance dose. Do not double doses. He is also the Innovation Lead for the Australian Centre for Health Innovation at Alfred Health and Clinical Adjunct Associate Professor at Monash University..

Group (A) consisted of 100 patients who received intravenous amiodarone over a 24-hour period as follows: 1 Loading (rapid) infusions: 3 mL of amiodarone intravenous (I.V.) Continuous infusion of 1 mg/min via IV for 6 hours, 0.5 mg/min via IV for subsequent 18 hours Amiodarone Precautions/Side Notes Atrial fibrillation, supraventricular arrhythmias and hypertrophic cardiomyopathy are typically treated with oral form of amiodarone. Patients' on the "floors" may receive once daily IV maintenance doses, however, IV loading regimens (multiple doses) are restricted to pts on a monitor- ICU's. IV to PO diltiazem: Oral dose = (IV drip rate [in mg/hr] x 3 + 3) x10 Steps to covert from diltiazem IV to PO 1. Therefore, although intravenous amiodarone at these doses appeared to have some efficacy, no effective dose range had been established to guide dosing in the clinical situation. 2. Loading dose given over a minimum of 20 minutes in the non-critical patient. The fatal dose of IV amiodarone is 1,200 to 1,500 mg . Adults—At first, 800 to 1600 milligrams (mg) per day taken in divided doses. Dosing.

When the maintenance dose is given IV, the onset and peak will occur earlier, however the duration of action is the same. A filter is not required for IV direct administration. Conversion from oral to IV: Decrease IV dose by 20 to 25%. Amiodarone was administered by continuous intravenous infusion to rats at dosages of 25 mg/kg per day, 50 mg/kg per day, or 100 mg/kg per day (about 0.3, 0.7, and 1.3 times the human intravenous maintenance dose of 0.5 mg/min on a body surface area basis) during gestation days 8 to 16 (organogenesis). If the patient achieves ROSC, a continuous infusion is started at 1 mg/min for 6 hours, followed by 0.5 mg/min. [1,2] IV amiodarone bolus dosing has been .

One hour after PO dose, titrate drip down by 2.5 mg/hr until . The present study was performed to determine whether intravenous amiodarone-induced hypotension persists beyond the loading dose and into the maintenance infusion period and also whether hypotension occurs with maintenance level dosing alone. Loading dose given as a slow IV push over 1-2 minutes in the critical patient. Loading dose: The standard recommended dose is 5mg/kg bodyweight given by intravenous infusion over a period of 20 minutes to 2 hours. 1- Using IV Amiodarone, provide the IV bolus dose using the standard Amiodarone bolus formulation currently FDA available.

Dosage Guidelines for Amiodarone (Cordarone) IV = intravenous; GI = gastrointestinal. Cordarone I.V. Amiodarone inhibits numerous CYP enzymes, including 3A4, 2D6, 2C9, 2C19, and P-glycoprotein. Eventually you will only be taking the medication once a day. 58 Because of the use of investigator-initiated, intermittent, open-label amiodarone boluses for recurrent VT, the actual mean amiodarone doses received by the 3 groups were 742, 1175, and 1921 mg/d. Amiodarone (Cordorone) IV to Oral conversion loading and maintenance dose calculator Amiodarone IV-Oral conversion and loading Calculation (s) used Determine the appropriate oral loading regime based on the cumulative dose received via the IV route, as follows: - Cumulative dose, X = (total IV dose * 2) - (days of treatment * 200); Amiodarone was given at a dose of 10 mg per kilogram of body weight each day for 14 days, followed by 300 mg per day for 4 weeks, after which a daily maintenance dose of 200 mg was given. Scheinman et al 1 conducted a double-blind, dose-ranging study comparing three different doses of intravenous amiodarone (125, 500, and 1000 mg/24 h). 2 Maintenance Infusion Amiodarone 900mg in 500mL Glucose 5% over 24 hours (21mL/hr) This may be continued as necessary according to response and . Amiodarone is an iodinated benzofuran derivative that was synthesized and tested as an antianginal agent in the 1960s but was later discovered to have antiarrhythmic properties. The loading regimen employed depends on the clinical indication and the rapidity of effect desired. 3. This loading dose worksheet is intended to guide medical, nursing and pharmacy staff in the safe and appropriate prescribing and administration of intravenous amiodarone loading doses in adults. Continuous IV infusion Add required amiodarone dose (usually 900mg, max 1200 mg) to 500mL glucose 5% and infuse using an electronically controlled pump over 23 - 24 hours (900mg) and 24 hours (1200mg). Amiodarone is only used after defibrillation (or cardioversion) and epinephrine (first line medication) fail to convert VT/VF. Although amiodarone is effective, it is not generally recommended for minor rhythm disturbances because of its toxicity. IV: Initial dose: 1000 mg over the first 24 hours of therapy, delivered by the following infusion regimen:-Loading infusions: 150 mg over the first 10 minutes (15 mg/min), followed by 360 mg over the next 6 hours (1 mg/min)-Maintenance infusion: 540 mg over the remaining 18 hours (0.5 mg/min) Amiodarone pharmacology.
