In rodents RTI-55 actually caused death at a dosage of 100 mg/kg, whereas RTI-51 and RTI-31 did not. Another notable observation is the strong propensity of RTI-55 to cause locomotor activity enhancements, although in an earlier study, RTI-51 was actually even stronger than RTI-55 in shifting baseline LMA.

The clinical diagnosis of Parkinson disease (PD) is difficult, as several other neurodegenerative and basal ganglia disorders have similar clinical presentations. Dopamine transporter single-photon emission computed tomography has been proposed as possible diagnostic tool to help differentiate idiopathic PD from essential tremor and other disorders that present with parkinsonian symptoms.

However, no direct comparison-studies of these two radiotracers as to their in vivo binding to 5-HT transporters have been reported so far. Therefore, it is still unclear which of the two radiotracers is more suitable for single photon emission computed tomography (SPECT) imaging of 5-HT transporters.
