Amiodarone necrosis

Main / Equipment (DME) / Amiodarone necrosis

The minimal cumulative dose is around g [ 7 ]. Amiodarone-induced skin pigmentation and multiple basal-cell carcinomas.


Continuous activation of gp, a signal-transducing receptor component for interleukin 6-related cytokines, causes myocardial hypertrophy in mice. They have the typical erythematous or eczematous appearance with accompanying pruritus in the parts exposed to sunlight, usually on the hands, face, and neck. The case was discussed with the plastic surgeons who decided not to proceed to skin grafting because of his acute myocardial infarction.

Compared with a stimulated control of 2. We do not capture any email address. A very rare adverse reaction to amiodarone treatment is linear IgA bullous dermatosis, and it is thought that amiodarone can exacerbate the course of this disease.

IL-6 production was decreased by amiodarone in all concentrations but was increased significantly by disopyramide. The symptoms begin several minutes after exposure to the sunlight, continue up to 24 hours and usually subside by around 48 hours, but in some cases they persist up to 72 hours.

The acute complication of treatment with intravenous amiodarone administration can take on the form of necrosis of the skin and soft tissue due to venous extravasation. Amiodarone binds to phospholipids and creates insoluble compounds that do not follow the regular degradation pathways, which leads to their accumulation in cellular lysosomes. Other Adverse Effects Less common dermatological complications of amiodarone include hives, pruritus, erythema nodosum, purpura, and the most severe variant of erythema multiforme — toxic epidermal necrolysis [ 2122 ].

In contrast to the phototoxic reactions, which do not depend on the skin type, hyperpigmentation usually occurs in patients with skin type I phototype [ 7 ].

A few cases of basal cell carcinoma associated with chronic use of this drug have been reported. Membrane current changes responsible for the positive inotropic effect of OPCa new positive inotropic agent, in single ventricular cells of the guinea pig heart. Vesnarinone, a new inotropic agent, inhibits cytokine production by stimulated human blood from patients with heart failure. The mechanism by which these changes occur is not precisely understood.

Two unusual cases of toxic epidermal necrolysis. Still, we run them but I keep an eye on them always.

The Committee for the Safety of Medicines has only two entries for amiodarone extravasation injury and nine for injection site reactions. Because significant interindividual variability of cytokine production by PBMC in response to LPS was observed, cytokine production from two to five subjects was measured 2 wells from each.
