Depression is serious and growing mental disorder of the mood that requires pharmacological treatment using antidepressant drugs. A range of antidepressants are currently available but their effectiveness is often limited and have several adverse side effects. Moreover, antidepressants generally require chronic administration for 2-4 weeks before clinical antidepressant activity is observed, which further affects patient compliance. Therefore, more effective and faster acting antidepressants are required to improve the treatment of depression.
