Systematic analysis of basic and clinical studies of etifoxine

The paper presents a systematic analysis of experimental and clinical studies of etifoxine. The anxiolytic effect of etifoxine is due, firstly, to the modulation of GABA receptor activity and, secondly, to that of metabolism of neurosteroids that are themselves characterized by anxiolytic and neuroprotective properties. The results of clinical trials of etifoxine are also analyzed. In addition to its anxiolytic effect that partially persists even after treatment discontinuation, etifoxine is ascertained to be characterized by analgesic, neurotrophic and neuroprotective properties.
