Amiodarone is a Class III antidysrhythmic medication used to treat ventricular arrhythmias. It is often used as part of ACLS and PALS algorithms for ventricular fibrillation and pulseless ventricular tachycardia following CPR loss and defibrillation. typically offered to patients with a fast ventricular rate (A-Fib RVR) atrial fibrillation, amiodarone inhibits arrhythmias by prolonging the capacity for intervention and the refractory duration. This induces and decreases the PR and QT frequency while also causing vasodilation. The drug is gradually absorbed in the GI tract when PO is taken and total bioavailability is reached when IV is given. When ingested, amiodarone is released across the body where it is contained in skin, tissue, kidney, lungs, and spleen. It is metabolized by the liver and excreted by bile. There is slight removal of amiodarone in the kidneys. NUR_641E Week 2 DQ1 Essay

            Amiodarone has been currently recommended by the American Geriatric Society (AGS) to prevent as a first-line usage in geriatric populations. This recommendation is focused on the AGSs Beers Guidelines regarding The Inappropriate Use of Medicine in Older Adults. nThe downside to this proposal is that the pacing of the patient is favored on the regulation of the rate. This is a significant factor in patients with heart failure, which is missing in a-fib, accounts for up to 28% of pre-loaded cases. Vallerand and Sanoski (2017 ) indicated that amiodarone should be used with caution in geriatric populations; suggesting doses to start at low end due to decreased renal, hepatic, and cardiac function, and other comorbidities.

With higher body concentrations being a stout prospect in the geriatric population, it will be essential to know the signs and symptoms of amiodarone toxicity. These include Blue-Man Syndrome, Bradycardia, Thyroid, Interstitial Lung Disease, Photosensitivity, Hypotension, and Hepatic Failure. The management of these patients requires continuous evaluation as the compensation mechanisms are slowed down.
