Panadiplon (U-78875) is an anxiolytic drug with a novel chemical structure that is not closely related to other drugs of this type. It has a similar pharmacological profile to the benzodiazepine family of drugs, but with mainly anxiolytic properties and relatively little sedative or amnestic effect, and so is classified as a nonbenzodiazepine anxiolytic.[1]
Panadiplon acts as a high-affinity GABAA receptor partial agonist,[2][3] but despite showing a useful effects profile of a potent anxiolytic with little sedative effects, panadiplon was discontinued from clinical development for use in humans after showing evidence of liver damage in both animals and human trials.[4][5] Panadiplon however continues to be used in animal research, mainly as a subtype-selective reference drug to compare other GABAA agonists against.[6][7]
