Lithium versus Quetiapine in Depression (LQD)

The Lithium versus Quetiapine in Depression (LQD) study is trying to work out which of two medications (lithium or quetiapine) added to an antidepressant is best in helping people with treatment resistant depression. The aim is to address the gap in the research literature on which of these medications is most effective over the course of a year. Future patients will benefit from the results of the study by knowing which (if any) treatment is more likely to improve their condition over a longer duration of time.

The study is being run from Northumberland, Tyne and Wear NHS Foundation Trust and the Tees, Esk and Wear Valleys NHS Foundation Trust. Recruitment began in December 2016 and is currently ongoing.
