RWJ-51204 is an anxiolytic drug used in scientific research. It has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.

RWJ-51204 is a nonselective partial agonist at GABA_A receptors.^[1] It produces primarily anxiolytic effects at low doses, with sedative, ataxia and muscle relaxant effects only appearing at some 20x the effective anxiolytic dose.^[2] It was discovered by researchers at the pharmaceutical company Johnson & Johnson,^[3]^[4] but its development has been discontinued.
