Side effects of oral amiodarone at doses of 400 mg or higher include various pulmonary effects. [44] The most serious reaction is interstitial lung disease . Risk factors include high cumulative dose, more than 400 milligrams per day, duration over two months, increased age, and preexisting pulmonary disease.
Amiodarone has both direct and indirect effects on thyroid function. The most notable indirect thyroid altering property is that the drug is approximately one-third iodine by weight. As a result, amiodarone therapy elevates free circulating iodine levels up to 40 times greater than the iodine intake from the average American diet. [2]
Amiodarone is also safe to use in individuals with cardiomyopathy and atrial fibrillation, to maintain normal sinus rhythm. Amiodarone prolongation of the action potential is uniform over a wide range of heart rates, so this drug does not have reverse use-dependent action. Amiodarone was the first agent described in this class. [4]
It starts by considering the range of pharmacological targets, and tracks these to their particular cellular electrophysiological effects. It retains but expands the original Vaughan Williams classes I to IV, respectively covering actions on Na+ current components, autonomic signalling, K + channel subspecies, and molecular targets related to ...
Pulmonary toxicity is the medical name for side effects on the lungs. Although most cases of pulmonary toxicity in medicine are due to side effects of medicinal drugs, many cases can be due to side effects of radiation (radiotherapy). Other (non-medical) causes of pulmonary toxicity can be chemical compounds and airborne particulate matter.
The U.S. Surgeon General's warning of an increased risk of cancer from drinking alcohol may end up resonating most with younger Americans - who in recent years were already turning to mocktails ...
Finally, the researchers did not take into account potential risks of screenings, such as false positives and overdiagnosis. Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health ...
Budiodarone (ATI-2042) is an antiarrhythmic agent and chemical analog of amiodarone that is currently being studied in clinical trials.Amiodarone is considered the most effective antiarrhythmic drug available, [1] [2] [3] but its adverse side effects, including hepatic, pulmonary and thyroid toxicity as well as multiple drug interactions, [4] are discouraging its use.
