Atrial fibrillation Supraventricular arrhythmias during pregnancy. Within individuals dose reductions and ensuing decreased plasma concentrations can result in loss of arrhythmia control. The most specific test of pulmonary toxicity due to amiodarone is a dramatically decreased DL CO noted on pulmonary function testing. May cause photosensitivity reactions.
Rate control off-label use: Skip to Content googletag. Elimination half-life average of 58 days ranging from 25— days [Remington: May cause hypotension and bradycardia infusion-rate related. Diagnosis of Systemic Lupus Erythematossus.
Dose adjustment may be needed. Contains the excipient cyclodextrin sulfobutyl ether beta-cyclodextrinwhich may accumulate in patients with renal insufficiency, although the clinical significance of this finding is uncertain Luke, Excipient information presented when available limited, particularly for generics ; consult specific product labeling. Management of life-threatening recurrent ventricular fibrillation VF or recurrent hemodynamically-unstable ventricular tachycardia VT refractory to other antiarrhythmic agents or in patients intolerant of other agents used for these conditions.
This is slowly and occasionally incompletely reversible on discontinuation of drug but is of cosmetic importance only. Amiodarone may enhance the anticoagulant effect of Vitamin K Antagonists. After a single dose of amiodarone injection in cirrhotic patients, C max was significantly lower and average concentration values were seen for desethylamiodarone, but mean amiodarone levels were unchanged.
Amiodarone may diminish the therapeutic effect of Sodium Iodide I International journal of cardiology. Seek alternatives to the CYP2C8 substrate when possible. The lowest effective dose should be used to prevent the occurrence of side effects. Amiodarone may decrease serum concentrations of the active metabolite s of Clopidogrel.
Patients taking amiodarone should not eat grapefruit or drink grapefruit juice because it can inhibit the conversion of amiodarone to an active metabolite.
Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals Isaksson, ; Lucente, ; Shelley, Maximum recommended total daily dose is 2. There is no present consensus on many aspects of how best to assess effectiveness, but there is a reasonable consensus on some aspects:.
The dose of amiodarone administered is tailored to the individual and the dysrhythmia that is being treated. Amiodarone may increase the serum concentration of Beta-Blockers. It is difficult to describe the effectiveness rates of amiodarone, as these depend on the specific arrhythmia treated, the success criteria used, the underlying cardiac disease of the patient, the number of drugs tried before resorting to amiodarone hydrochloride, the duration of follow-up, the dose of amiodarone hydrochloride, the use of additional antiarrhythmic agents, and many other factors.
