Further study details as provided by AstraZeneca:

Primary Outcome Measures:

Positron emission tomography using the radioligand (11C)flumazenil [ Time Frame: 4 times per subject ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To assess safety of AZD7325 by assessment of adverse events, vital signs, ECGs, physical examination, psychometric tests and laboratory variables. [ Time Frame: 6 visits with tests for the 2 subjects in the first group (Panel 1). 7 visits with tests for the 2 subjects in the second group (Panel 2). Some tests will be done several times per visit. All tests will not be done at every visit ] [ Designated as safety issue: No ]
Investigate the pharmacokinetics of AZD7325 following single doses of AZD7325 by assessment of drug concentration in plasma [ Time Frame: 3 times per subject. Up to 48 hours each time. ] [ Designated as safety issue: No ]
