Desmethoxyfallypride is a moderate affinity dopamine D2 receptor/D3 receptor antagonist used in medical research, usually in the form of the radiopharmaceutical [F-18]-desmethoxyfallypride (DMFP(18F))[1][2] which has been used in human studies as a positron emission tomography (PET) radiotracer.[3][4]
