A chest X-ray demonstrating pulmonary fibrosis due to amiodarone. 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 ...
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
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]
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.
As an example to illustrate what can be done, the use of the medicinal drug amiodarone: a) Prescribing the lowest possible dose of amiodarone leads to a lower incidence of pulmonary toxicity. [17] b) Regular monitoring, in order to diagnose any possible pulmonary toxicity early. [18] [19] c) Discontinuation as soon as pulmonary toxicity is ...
Grapefruit is a nutrient-packed, low-calorie food that’s a delicious addition to your diet. However, it can interact with certain medications. So, if you take medication, check with your doctor ...
The therapeutic window (or pharmaceutical window) of a drug is the range of drug dosages which can treat disease effectively without having toxic effects. [18] Medication with a small therapeutic window must be administered with care and control, frequently measuring blood concentration of the drug, to avoid harm.
