Benzodiazepines are the most prescribed anxiolytics and are used by a broad population. However, benzodiazepines can cause unwanted side effects, including sedation, development of tolerance, and withdrawal symptoms after long-term administration. Rupprecht et al. now find that a translocator protein (18 kD) ligand, XBD173, is a fast-acting anxiolytic agent, both in animals and humans, which lacks the unwanted side effects of benzodiazepines and provides a promising target for novel clinically effective anxiolytic drugs.
