Etifoxine (EFX), at concentrations ranging from 10 to 300 μM (higher concentrations limited its solubility), produces a dose-dependent increase in the [3H]muscimol binding at equilibrium, to 155±2% of its control value at 300 μM EFX.
Etifoxine competitively inhibits [
35
S]TBPS binding with micromolar potency in rat brain.
Etifoxine (3.125-50 mg/kg) exhibits more pronounced anxiolytic and anticonvulsant effects in the BALB/cByJ mice compared to the C57BL/6J mice.
| Animal Model: | Six-week old BALB/cByJ and C57BL/6J mice (20-25 g). |
| Dosage: | 3.125-50 mg/kg. |
| Administration: | Intraperitoneal injection. |
| Result: |
Significantly increased the amount of time spent on the open arms at the 12.5 mg/kg dose when compared to vehicle (p = 0.009) in BALB/cByJ mice but produced no effect in C57B/6J mice.
BALB/cByJ mice compared with C57BL/6J mice exhibited significantly (p < 0.012) lower plasma levels of the compound at 15 and 30 min. |
