Study summary

The purpose of this study is to identify evidence-based guidelines for treating major depressive disorder to full remission in Taiwanese major depressive disorder (MDD) patients. To achieve this goal, the investigators aim to: (1) evaluate the risks and benefits of adjunctive pharmacotherapies for cognitive and metabolic consequences in MDD, and (2) clarify the shared biological mechanisms between mood, immune and metabolism homeostasis

Read the detailed description

The prevalence of insulin resistance did not significantly differ among the healthy controls and drug-naïve MDD patients before and after antidepressant treatment. Meanwhile, the current study indicated that antidepressants might affect insulin secretion independently of the therapeutic effects on MDD. Therapeutic strategies considering both treatment effectiveness and glucose-insulin homeostasis in MDD patients are necessary.

    Drug: Fluoxetine + Valsartan

  • Active comparator
    Fluoxetine + Placebo

    The initial dose of fluoxetine was 20 mg once daily, which could be increased by 20 mg in divided doses to a maximal daily dose of 60 mg. Add-on treatment to placebo

    Drug: Fluoxetine + Placebo

Interventions

  • DrugFluoxetine + Valsartan

    The curative effect of fluoxetine add-on valsartan 40 mg per day for 12 weeks therapy in the treatment of major depressive disorder.

    Also known as: Prozac, Diovan

  • DrugFluoxetine + Placebo
