Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	Potassium channel Sodium channel Calcium channel
In vitro	Dronedarone reduces the incidence of early and delayed after depolarizations evoked by 1 mM Dofetilide and 0.2 mM Strophantidine in Purkinje fibres. Dronedarone (10 mM) markedly reduces the L-type calcium current (76.5%) and the rapid component of the delayed rectifier potassium current (97%) in ventricular myocytes. Dronedarone inhibits the activity of I(K(ACh)) channels recorded from cell-attached patches by reducing the channel open probability (from 0.56 to 0.11) without modification of the single-channel conductance in single cells isolated from sinoatrial node (SAN) tissue of rabbit hearts. Dronedarone exhibits a state-dependent inhibition of the fast Na(+) channel current with an IC50 of 0.7 μM in guinea pig ventricular myocytes, when the holding potential (V (hold)) is -80 mV. Dronedarone blocks Ca(2+) currents elicited by rectangular pulses at V (hold) = -40 mV with IC50 value of 0.4 μM, whereas at V (hold) = -80 mV, Dronedarone (10 μM) blocks only 20 % of the current.
In vivo	Dronedarone increases action potential duration in normal hearts of rats. Dronedarone reduces the late sustained K(+) current, I(K) (or Isus) by 69%. Dronedarone induces only a tonic block of I(K). Dronedarone induces a weak increase in the fast transient outward current, I(to), in rats after myocardial infarction.
