In India, amiodarone is marketed (produced by Cipla Pharmaceutical) under the brand name Tachyra. It is also available in intravenous ampules and vials. The dose of amiodarone administered is tailored to the individual and the dysrhythmia that is being treated. When administered orally, the bioavailability of amiodarone is quite variable ...
Amiodarone induced thyrotoxicosis (AIT) is a form of hyperthyroidism due to treatment with antiarrhythmic drug, amiodarone. Amiodarone induced thyroid dysfunction more commonly results in hypothyroidism , estimated to occur in 6-32% of patients, whereas hyperthyroidism from amiodarone use is estimated at 1-12%. [ 1 ]
Compounds that prolong the action potential: matching the modern classification, with the key drug example being amiodarone, and a surgical example being thyroidectomy. This was not a defining characteristic in an earlier review by Charlier et al. (1968), [ 17 ] but was supported by experimental data presented by Vaughan Williams (1970).
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.
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]
Dronedarone has been termed a "multichannel blocker". [citation needed] However, it is unclear which channel(s) play a pivotal role in its success. [9]Thus, dronedarone's actions at the cellular level are controversial, with most studies suggesting an inhibition in multiple outward potassium currents including rapid delayed rectifier, slow delayed rectifier and ACh-activated inward rectifier.

The code of ethics issued by the Medical Council of India in 2002 calls for physicians to prescribe drugs by their generic names only. [77] India is a leading country in the world's generic drugs market, with Sun Pharmaceuticals being the largest pharmaceutical company in India. Indian generics companies exported US$17.3 billion worth of drugs ...
The Jod-Basedow effect (also Jod-Basedow syndrome and Jod-Basedow phenomenon) is hyperthyroidism following administration of iodine or iodide, [1] either as a dietary supplement, for iodinated contrast medical imaging, or as a medication (mainly amiodarone).
