The binding of haloperidol to human blood platelets and interactions with 5-hydroxytryptamine and dopamine.

abstract：BACKGROUND AND PURPOSE:The Na+/Ca2+ exchanger (NCX) may contribute to triggered activity and transmural dispersion of repolarization, which are substrates of torsades de pointes (TdP) type arrhythmias. This study examined the effects of selective inhibition of the NCX by SEA0400 on the occurrence of dofetilide-induced ...
