potassium channel inhibitor sodium channel inhibitor amiodarone (2-butyl-1-benzofuran-3-yl){4-[2-(diethylamino)ethoxy]-3,5-diiodophenyl}methanone 2023-11-17T11:29:29Z Amiodarona Amiodaronum CHEBI:2663 Cordarone PMID:32119089 This is any condition in which the main influencing factor is amiodarone, an antianginal and class III antiarrhythmic drug that increases the duration of ventricular and atrial muscle action by inhibiting potassium channels and voltage-gated sodium channels. Following the channel inhibition is a resulting decrease in heart rate and in vascular resistance. XCO:0001124 experimental_condition_ontology slaulederkind
