Primary Outcome Measures
NameTimeMethod
Estimation of the plasma concentration resulting in 50% receptor occupancy (Ki, pl).Venous blood samples for determination of concentrations of AZD5213 in plasma will be taken on many occasions from pre-dose until 48 h post-dose.

Each healthy volunteer in the main panel will complete 3 PET measurements using radioligand; one at baseline and 2 after treatment with AZD5213.

Distribution volume (VT)Venous blood samples for determination of concentrations of AZD5213 in plasma will be taken on many occasions from pre-dose until 48 h post-dose. Single PET measurement will take maximum 2 hours.
Secondary Outcome Measures
NameTimeMethod
Adverse eventsCollected from Day 1 to follow-up
Vital signs (body temperature, BP and pulse)Measured at screening, study days -1 to day 3 and at follow-up
