Etifoxine

Etifoxine, sold under the trade name Stresam among others, is a nonbenzodiazepine anxiolytic agent, primarily indicated for short-term management of adjustment disorder, specifically instances of situational depression accompanied by anxiety, such as stress-induced anxiety. Administration is by mouth. Side effects associated with etifoxine use include slight drowsiness, headache, skin eruptions, and allergic reactions. In rare cases, etifoxine has been linked to severe skin and liver toxicity, as well as menstrual bleeding between periods. Unlike benzodiazepines, etifoxine does not cause sedation or lack of coordination. Etifoxine acts as a ligand for translocator proteins. Etifoxine was developed in the 1960s and was introduced for medical use in France in 1979. Its marketed in 53 countries worldwide, although it remains unavailable in the United States. Throughout the 2010s and early 2020s, the safety profile of etifoxine was scrutinized within France and the European Union, prompted by reports of toxicity. The investigation revealed that instances of toxicity were infrequent, and etifoxine was allowed to remain on the market.
