| Bioactivity | Flunarizine dihydrochloride is a potent dual Na+/Ca2+ channel (T-type) blocker. Flunarizine dihydrochloride is a D2 dopamine receptor antagonist. Flunarizine dihydrochloride shows anticonvulsive and antimigraine activity, and peripheral vasodilator effects[1][2][3][4][5]. |
| Invitro | Flunarizine blocks sodium currents (INa) and calcium currents (ICa) with IC50 values of 0.94 μM and 1.77 μM in cultured rat cortical neurons, respectively[2].Flunarizine (10 and 30 μM; 24 h) shows cytotoxic effects to chromaffin cells[4].Flunarizine (1-30 μM) causes clear cytoprotection of chromaffin cell at concentrations of 3-10 μM[4].
