Fananserin (RP-62203) is a drug which acts as a potent antagonist at both the 5HT_2A receptor,^[1] and the Dopamine D₄ receptor,^[2] but without blocking other dopamine receptors such as D₂.^[3] It has sedative^[4] and antipsychotic effects, and has been researched for the treatment of schizophrenia,^[5] although efficacy was less than expected and results were disappointing.^[6]
