    Product Description

    Zatebradine is a bradycardic compound that blocks hyperpolarization-activated inward current (If) through cyclic nucleotide-gated cation (HCN) channels in sinoatrial node cells (IC50s = 1.83, 2.21, 1.9, and 1.88 µM, respectively for HCN1-4 in vitro).1,2 Additionally, it can block voltage-gated outward K+ (IK) currents and related neuronal hyperpolarization-activated inward current (Ih) channels, but exhibits little or no activity for L-type Ca2+ (ICa) currents.3,4 When assessed through telemetric ECG recording in mice, zatebradine reduced heart rate from 600 to 200 beats per minute with an ED50 value of 1.8 mg/kg and induced increasing arrhythmia at concentrations >10 mg/kg.1
