SB-242,084 is a psychoactive drug and research chemical which acts as a selective antagonist for the 5HT2C receptor.[1] It has anxiolytic effects,[2] and enhances dopamine signalling in the limbic system,[3] as well as having complex effects on the dopamine release produced by cocaine, increasing it in some brain regions[4][5] but reducing it in others.[6][7] It has been shown to increase the effectiveness of the selective serotonin reuptake inhibitor (SSRI) class of antidepressants, and may also reduce their side effects.[8][9] In animal studies, SB-242,084 produced stimulant-type activity and reinforcing effects, somewhat similar to but much weaker than cocaine or amphetamines.[10]
