Amiodarone hydrochloride, a benzofuran-based Class III antiarrhythmic agent, inhibits WT outwardIhERG tails with an IC₅₀ of ∼45 nM^[1]. Amiodarone hydrochloride induces cell proliferation and myofibroblast differentiation via ERK1/2 and p38 MAPK signaling in fibroblasts^[2]. Amiodarone hydrochloride can be used in the research of both supraventricular and ventricular arrhythmias^[1].

Amiodarone blocks inward IhERG tails in a high K⁺ external solution ([K⁺]e) of 94 mM with an IC₅₀ of 117.8 nM^[1].
Amiodarone (1 μM) blocks inwardIhERG by 68.8±6.1%, with concentration response data yielding IC₅₀ and h values of 765.5±287.8 nM and 0.9±0.4 for T623A hERG^[1].
Amiodarone (1 μM) blocks inward IhERG with an IC₅₀ and h values of 979.2±84.3 nM and 1.1±0.1 for S624A hERG^[1].
Amiodarone (1-6 μg/mL) induces human embryonic lung fibroblasts (HELFs) cell proliferation and PD98059 or SB203580 suppresses this effect^[2].
Amiodarone (1-6 ug/mL) does not induces HELFs cell apoptosis. Amiodarone (over 15 ug/mL) induces cell apoptosis^[2].
Amiodarone (1, 3 and 6 μg/mL;24 hours) induces α-SMA and vimentin mRNA and protein expression accompanied by increased phosphorylation of ERK1/2 and p38 MAPK^[2].
