Potassium channel blockers exhibit reverse use-dependent prolongation of the action potential duration. Reverse use dependence is the effect where the efficacy of the drug is reduced after repeated use of the tissue. [11] This contrasts with (ordinary) use dependence, where the efficacy of the drug is increased after repeated use of the tissue.

A potassium channel opener is a type of drug which facilitates ion transmission through potassium channels. Examples. Some examples include: Diazoxide [1] ...
Example of voltage-dependent potassium ion channel in relation to changing ion concentrations . To comprehend the mechanism of channel blockers, it is critical to understand the composition of ion channels. Their main function is to contribute to the resting membrane potential of a cell via the flow of ions through a cell membrane.
Potassium channel blockers Amiodarone; Dofetilide; Dronedarone; E-4031; Ibutilide; Sotalol; Vernakalant; K + channel blocker. Sotalol is also a beta blocker [5] Amiodarone has mostly Class III activity, but also I, II, & IV activity [6] Prevent paroxysmal atrial fibrillation [7] and haemodynamically stable ventricular tachycardia [8] (amiodarone)
