GSK239512 displayed asatisfactory level of tolerability in patients with Alzheimer's disease with evidence for positive effects on attention and memory. The findings suggest that a titration regimen with a starting dose of 5-10 μg and a maximum dose of 80 μg is likely to be a well-tolerated and potentially efficacious regimen for future clinical trials in patients with Alzheimer's disease. These findings await replication in a larger study.

Binding of [123I]ADAM to SERT in midbrain can be quantified with a single scan starting 200 min after injection. However, the variability of estimated occupancy values may be too high for critical assessment of occupancy of SERT by SSRI.
