A calcium channel blocker
Mirogabalin is a calcium channel blocker with analgesic effects.1 It binds to the α2δ-1 and α2δ-2 subunits of voltage-dependent Ca2+ channels. Mirogabalin has potent and sustained analgesic effects (ED50 = 2.5 mg/kg) in rats with diabetes induced by streptozotocin . Mirogabalin does not inhibit activities associated with CNS adverse effects of analgesics, such as rotarod performance (ID50 = 9.4 mg/kg) or locomotor activity (ID50 = 43.9 mg/kg), at its effective dose.

Animal experiment: | Rats[1]Eighty male rats are divided into groups of eight. After oral administration of Mirogabalin besylate (1, 3, 10, 30, and 100 mg/kg) or vehicle (control), locomotor activity is measured for 1 hour using the SUPERMEX system. Based on the time of peak effects of the test compounds (Mirogabalin besylate, etc.) in the rota-rod test, the pretreatment time is set at 6 hours for mirogabalin besylate and at 4 hours for pregabalin[1]. |
