Lerisetron is a potent 5-HT3 antagonists and possess high-affinity binding for the 5-HT3 receptors with pKi value of 9.2. Lerisetron has a potent ability to inhibit the 5-HT-evoked reflex bradycardia in urethane-anesthetized rats[1]. IC50 & Target: pKi: 9.2 (5-HT3)[1] In Vivo: Lerisetron (50-200 μg/kg; IV; single) exhibits CL of 0.004-0.005 L/min, Vds of 0.88-0.96 L, MRT0-LAST of 224-337.1 min and AUC of 57.7-66.1 μg·min/L in rats[2].
Lerisetron (2-10 μg/kg; IV; single) causes rapid recovery from bradycardia[2].
