Losartan has been shown to accelerate fear extinction in animals and to prevent the development of anxiety disorders in humans, emphasising its potential to possibly enhance exposure therapy in humans. This study explores the basic effects of losartan on emotional processing, to identify neural mechanisms by which the drug might have synergistic effects on psychological treatment in humans. In a double-blind between-groups design, 30 healthy volunteers will be randomised to a group receiving a single dose of losartan (50mg) versus placebo, and this study will measure the effects of probing renin-angiotensin function on emotional information processing, using functional magnet resonance imaging (fMRI). Such knowledge will ultimately be essential for the development of more effective pharmaco-psychological treatment approaches for anxiety disorders.
