IC50: 25 μM (K+ current)[1]

In Vitro Application of 10, 30, 100 and 300 μM Sematilide causes a concentration-dependent inhibition of the delayed rectifier K+ current (IC50=25 μM)[1].
In Vivo Sematilide (0.3-1.0 mg/kg, intravenously i.v.) is effective in a canine model of arrhythmia[2]. Animal Model: Mongrel dogs of either sex (10-18 kg body weight)[2] Dosage: 0.3, 1, 3, and 10 mg/kg Administration: I.v. infusions Result: Demonstrated antiarrhythmic effects at 0.3 and 3.0 mg/kg.
