LABELED IODINATED TROPANE FORMULATION

摘要

PROBLEM TO BE SOLVED: To provide a formulation for diagnosis.SOLUTION: A formulation for diagnosis comprising tropane having a radioactivity concentration of at least 1.6 mCi/mL at least about 51 hours after production is provided. This formulation for diagnosis comprises, if needed, a radioactive isotope-labeled dopamine transporter (DAT) ligand useful for diagnosis of Parkinson disease (PD). One example of the radioactive isotope-labeled dopamine transporter (DAT) ligand is [123-iodine]-2&bgr;-carbomethoxy-3&bgr;-(4-fluorophenyl)-N-(3-iodo-E-allyl) nortropane.
