Learn More- Pharmacodynamics
iodine-123 labeled ioflupanebinds selectively to striatal presynaptic dopamine neurons by binding reversibly to presynaptic dopamine transporters.
- Mechanism of action
Iodine-123 labeled ioflupane binds to presynaptic dopamine transporters. When Iodine-123 decays, a gammay ray is emmitted and detected through SPECT.
- Absorption
Absorption is 100% because administered I.V.
- Volume of distribution
Compared to the entire brain, about 30% of radioactivity is taken up by the striatum.
