Nofecainide (RP 30356, nofedone) is a Class I antiarrhythmic agent. RP 30356 blocked the action potential of frog atrial fibres without noticeably altering the resting membrane potential. RP 30356 inhibited the fast sodium conductance without changing the selectivity of the Na channel. The time to peak of the inward current was not significantly altered by the drug whereas the rate of the Na current inactivation pi h was slowed. The steady state inactivation membrane potential relationship of the Na system was shifted toward negative membrane potentials by the drug. The inhibition of the Na conductance by RP 30356 was frequency-dependent. RP 30356 might be effective in the control of cardiac arrhythmias since it mainly decreased the excitability of depolarized fibres.
