| umls-concept:C0086303 | skos:definition | NCI: The acetate salt form of flecainide, a synthetic agent derived from trifluoroethoxy-benzamide exhibiting antiarrhythmic and local anesthetic activity. As a class Ic antiarrhythmic that blocks sodium channels, flecainide depresses polarization phase 0 and decreases the induction velocity of the His-Purkinje system. It also decreases phase 4 slope and increases the depolarization threshold. | lld:umls |
