Brief Summary:
The purpose of this study is to determine a dose of the investigational drug betahistine dihydrochloride that is both well tolerated and potentially effective in treating the symptoms of atypical depression. Atypical depression is characterized by the ability of the person's mood to improve temporarily in response to positive events, as well as features such as increased appetite, increased sleep and severe fatigue.

Condition or disease Intervention/treatment Phase
Recurrent Major Depressive Disorder With Atypical Features Drug: betahistine dihydrochloride Phase 2

Detailed Description:
All patients will start taking 50 mg of betahistine dihydrochloride on treatment day 1 (after baseline visit). Starting on day 4, the daily dose will be increased by adding a 50 mg dose. If tolerated, the daily dose will be titrated to 200 mg. At the end of week 3, the dose will be titrated to 300 mg.
