Pharmacokinetics in children

A very small-scale study (n=4, ages 1 month to 14.9 years) showed that the half-life in children can be shorter than in adults (6.9 to 11.4 days). The half-life in adults is approximately 40 days. This study also showed that the clearance decreases as age increases. The study by Ramusovic (2013) shows that the serum concentrations in children aged from 6 days to 15 years are the same as those in adults.

Side effects in children

Gastrointestinal complaints, hypothyroidism and hyperthyroidism, acute impaired liver function, photosensitization, neuropathy, microscopic corneal precipitation, bradycardia, pulmonary toxicity. Specific side-effects are possible after intravenous administration: localized reactions such as phlebitis, transient flushes and sweating, sudden blood pressure drops and increased heart rate, anaphylactic shock. After intravenous bolus injection: risk of severe hypotension and cardiovascular collapse. The side effects are largely the consequence of doses that are too high; the lowest effective dose should therefore be used.

Warnings & precautions in children

Amiodarone may only be prescribed by expert specialists under careful monitoring of the hepatic function, the thyroid function, the ECG and X-ray examination of the thorax. Intravenous administration should be done in a clinic with monitoring of the ECG and blood pressure. In severe pulmonary insufficiency, arterial hypotension or stable cardiac failure (in particular in cardiomyopathy), extra caution is recommended and a bolus injection is contraindicated. A second bolus injection may not be given within 15 minutes of the first one. Infusion of amiodarone (repeated infusions in particular) via peripheral veins can cause thrombophlebitis; repeated administrations in particular should be done via a central line. Vials of amiodarone liquid for injection contain benzyl alcohol. There have been reports of fatal gasping syndrome in new-borns, in particular children with a low birthweight, after administration of intravenous solutions with benzyl alcohol
