Raclopride is a typical antipsychotic. It acts as a selective antagonist on D2 dopamine receptors. It has been used in trials studying Parkinson Disease.
Raclopride is selective for D2 and D3 dopamine receptors. {| class="wikitable" style="float:right; margin-left:1em; |+Binding profile !Receptor !Ki |- |D1 |18000 nM |- |D2 |1.8 |- |D3 |3.5 |- |D4 |2400 |} It can be radiolabelled with radioisotopes, e.g. 3H or 11C and used as a tracer for in vitro imaging (autoradiography) as well as in vivo imaging positron emission tomography (PET). Images obtained by cerebral PET scanning (e.g. PET/CT or PET/MRI) allow the non-invasive assessment of the binding capacity of the cerebral D2 dopamine receptor, which can be useful for the diagnosis of movement disorders. In particular, cerebral D2 receptor binding as measured by carbon-11-raclopride (11C-raclopride) has shown to reflect disease severity of Huntington's disease, a genetic disease characterized by selective degeneration of cerebral D2 receptors.
