Mechanism of action

Raclopride C11 binds competitively to dopamine D2 and D3 receptors in the brain and is labeled with the radioactive isotope carbon-11, allowing visualization and quantification of dopamine receptor density and occupancy via PET imaging. It is used as a diagnostic tool to assess dopaminergic neurotransmission in research and clinical settings, particularly in neuropsychiatric and neurodegenerative disorders.
