IV 1.5 mg and 3.0 mg twice daily for 3 days, IV 5.0 mg and 10.0 mg twice daily for 11 days, IV between 2.5 mg and 10 mg per dose, or: 3 mg b.i.d for 3 days iv, followed by 10 mg b.i.d for 11 days p.o and 1,5 mg bid for 3 days i.v, then 5 mg b.i.d for 11 days p.o with 3 month follow-up.

The effect of eliprodil on P-type Ca2+ channels was investigated in acutely dissociated rat Purkinje neurons, by using the whole-cell patch-clamp technique. Eliprodil inhibited in a reversible manner the omega-agatoxin-IVA-sensitive Ba2+ current elicited by step depolarizations from a -80 mV holding voltage (IC50 = 1.9 microM). The Ba2+ current showed steady-state inactivation (V1/2 = -61 mV) which was shifted toward more positive values when the intracellular Ca2+ buffering was increased. In these conditions, the potency of eliprodil was decreased (IC50 = 8.2 microM), suggesting a modulation by intracellular Ca2+ of the eliprodil blockade.
