Trazpiroben (developmental code name TAK-906) is a dopamine antagonist drug which was under development for the treatment of gastroparesis.^[1]^[2]^[3]^[4]^[5] It acts as a peripherally selective dopamine D₂ and D₃ receptor antagonist.^[1]^[2] The drug has been found to strongly increase prolactin levels in humans, similarly to other peripherally selective D₂ receptor antagonists like domperidone.^[5] Clinical development of trazpiroben was discontinued before April 2022.^[1] Trazpiroben was originated by Altos Therapeutics and was under development by Takeda Oncology.^[1]
