Mibefradil dihydrochloride hydrate (Ro 40-5967 dihydrochloride hydrate) is a effectively long-acting calcium channel antagonist, used as an antihypertensive agent. Mibefradil dihydrochloride hydrate acts via a higher affinity block for low-voltage-activated (T) than for high-voltage-activated (L) calcium channels[1].

In Vitro	Mibefradil inhibits reversibly the T- and L-type currents with IC50 values of 2.7 and 18.6 μM, respectively[2]. Mibefradil (20 µM) reduces the amplitude of excitatory junction potentials (by 37±10 %), slows the rate of repolarisation (by 44±16 %) and causes a significant membrane potential depolarisation (from -83±1 mV to -71±5 mV)[3].
