Medline ® Abstract for Reference 10 of 'Amiodarone: Clinical uses' - UpToDate. 1) IV metoprolol has immediate action, PO has slow and graded release over hours. Renal impairment does not influence the pharmacokinetics of amiodarone. Intravenous amiodarone can cause acute hypotensive reactions and is often damaging to veins so it should normally be given through a central line. The dosage in dogs is 0.05-0.2 mg/kg, IV, over 5 min, which can be repeated to a cumulative dose of 0.3 mg/kg, after which the dog should be reassessed or an oral formulation initiated.

This updated dose conversion is based on recent literature which has shown that the bioavailability of levothyroxine is estimated to be around 79-81 percent.3 Based on this data, the ATA Guidelines and Lexicomp recommend administering an IV dose that is 75 percent of the oral dose when converting from a parenteral to enteral route. Eventually transition to another agent. Dosage regimens vary, but a regimen commonly used in adults in Australia is 300 mg infused over a period of 20 minutes to two hours, followed by a further 900 mg over the next 24 hours (with . The objective of this study was to assess the impact of IV and PO amiodarone overlap on short-term tachyarrhythmia recurrence and adverse hemodynamic outcomes in the intensive care unit. This will change the medication concentration. Automatic IV to PO Conversion Protocol Purpose: To allow for the conversion of intravenous medications to oral equivalents when medically appropriate in an effort to reduce line-associated risk, reduce nosocomial-acquired infection risk, improve patient satisfaction, promotes earlier and easier ambulation, and reduce Alternative regimen of amiodarone: 600 mg/day for 7 days prior to surgery, followed by 200 mg/day until hospital discharge, has also been shown to decrease the risk of postoperative atrial fibrillation.
