Recainam hydrochloride
Recainam (Wy-42362) hydrochloride is a potent orally active antiarrhythmic agent and a sodium channel inhibitor. Recainam hydrochloride elevates ventricular fibrillation threshold, suppresses induced cardiac dysrhythmias, and may accentuate cardiac tissue refractoriness heterogeneity. Recainam hydrochloride can be used for the research of arrhythmias.

Biological Activity
Recainam (10-300 μM; ≥30 min) hydrochloride has no significant effect on key electrophysiologic variables of isolated rabbit sinoatrial node preparations, aside from modestly shortening action potential duration[2].
Recainam (10-100 μM; ≥30 min) hydrochloride significantly reduces the maximal rate of rise of phase 0 (V̇max) in isolated rabbit atrial muscle preparations without altering other key electrophysiologic variables[2].
Recainam (10-300 μM; ≥30 min) hydrochloride causes concentration-dependent reductions in the maximal rate of rise of phase 0 (V̇max) in isolated canine ventricular muscle preparations without altering action potential duration or effective refractory period[2].
Recainam (1-300 μM; ≥30 min) hydrochloride causes concentration-dependent reductions in the maximal rate of rise of phase 0 (V̇max), action potential amplitude, action potential duration, and effective refractory period in isolated canine Purkinje fiber preparations[2].
Recainam (10-60 μM; ≥30 min) hydrochloride shifts the membrane responsiveness curve in the hyperpolarizing direction in isolated canine Purkinje fiber preparations, with higher concentrations abolishing premature responses from depolarized membrane potentials[2].
Recainam (300 μM; ≥30 min) hydrochloride induces a frequency-dependent reduction in the maximal rate of rise of phase 0 (V̇max) in isolated canine Purkinje fiber, canine ventricular muscle, and rabbit atrial muscle preparations, and abolishes responses at frequencies >3 Hz in Purkinje fibers[2].
Recainam (100 μM; ≥10 min) hydrochloride depresses phase 4 depolarization and slows isoproterenol-induced automaticity in isolated canine Purkinje fiber preparations[2].
Recainam (300 μM; ≥30 min) hydrochloride does not affect slow channel-dependent potentials induced by high potassium and isoproterenol in isolated canine ventricular muscle and Purkinje fiber preparations[2].
