Focus on Class I drugs comprised amiodarone, atorvastatin, carvedilol, cyclosporine.
As a result amiodarone increases the duration of the action potential as well as the effective refractory period for cardiac cells (myocytes). Amiodarone is an antiarrhythmic drug with structural similarities to thyroxine. It exhibits all four of the classic Vaughan Williams mechanisms of action, namely sodium and potassium channel blockade, a mild antisympathetic action and some calcium channel blockade, but it is usually classified as a Class III antiarrhythmic drug (see Table 1).
