Buspirone (C0006462)

Definition (MSH)An anxiolytic agent and a serotonin receptor agonist belonging to the azaspirodecanedione class of compounds. Its structure is unrelated to those of the benzodiazepines, but it has an efficacy comparable to DIAZEPAM.
Definition (CSP)8-(4-(2-pyrimidinyl)-1-piperazinyl) butyl-8-azaspirodecane-7,9- dione; serotonergic tranquilizer frequently contrasted with benzodiazepine-type, GABAergic tranquilizers.
Definition (NCI)An anxiolytic agent chemically and pharmacologically unrelated to benzodiazepines, barbiturates, or other sedative/hypnotic drugs. Although its exact mechanism of action is unknown, buspirone may exert its anti-anxiety effects via serotonin (5-HT1A) and dopamine receptors (D2) and may indirectly affect other neurotransmitter systems. Unlike typical benzodiazepine anxiolytics, this agent does not exert anticonvulsant or muscle relaxant effects and lacks prominent sedative effects.
