AbstractThe effects of ebastine and terfenadine, long-acting nonsedating histamine H1 receptor antagonists, were studied on hKv1.5 channels using the whole-cell voltage-clamp configuration of the patch-clamp technique in Ltk- cells transfected with the gene encoding the hKv1.5 channel. Upon depolarization to +60 mV, terfenadine, 1 μM and 3 μM, inhibited the hKv1.5 current by 42.4 ± 6.4% and 69.3 ± 4.2% (P < 0.01). In contrast, at the same range of concentrations, ebastine-induced inhibition of this K+ current averaged 6.5 ± 2.0% and 13.0 ± 2.0 (P < 0.05). At the highest concentration tested (3 μM) neither terfenadine carboxylate nor carebastine significantly modified hKv1.5 current. All these results suggest that ebastine could represent a safer alternative to terfenadine in the clinical practice.
