We examined the effects of the selective serotonin reuptake inhibitor (SSRI) sertraline on voltage-dependent K+ (Kv)channels in freshly isolated rabbit coronary arterial smooth muscle cells using the voltage-clamp technique. Sertralinedecreased the Kv channel current in a dose-dependent manner, with an IC50 value of 0.18 μM and a slope value (Hillcoefficient) of 0.61. Although the application of 1 μM sertraline did not affect the steady-state activation curves,sertraline caused a significant, negative shift in the inactivation curves. Pretreatment with another SSRI, paroxetine,had no significant effect on Kv currents and did not alter the inhibitory effects of sertraline on Kv currents. From theseresults, we concluded that sertraline dose-dependently inhibited Kv currents independently of serotonin reuptakeinhibition by shifting inactivation curves to a more negative potential.
