Buspirone (C0006462)

Definition (NCI_NCI-GLOSS) A drug that is used to treat certain anxiety disorders. It belongs to the family of drugs called antianxiety agents.
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.
Definition (MSH) An anxiolytic agent and serotonin receptor agonist belonging to the azaspirodecanedione class of compounds. Its structure is unrelated to those of the BENZODIAZAPINES, 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.
