Allopurinol in Depression

May 1, 2026 updated by: Mostafa Bahaa, Tanta University

Allopurinol Adjuvant Therapy in Patients With Major Depressive Disorder

Major depressive disorder (MDD) is one of the most common psychiatric disorders with serious socioeconomic consequences on daily life and health care costs. Despite the advent of newer antidepressants that target monoamine pathways, nearly 50% of patients have no response to first-line antidepressant therapy. Thus, a combination of medications with different strategies at the beginning of treatment could provide further therapeutic benefits to MDD patients.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in the 17-item Ham-D depression score.
Time Frame: 8 weeks
Ham-D depression is a widely used clinician-administered instrument designed to assess the severity of depressive symptoms over the preceding week. It consists of 17 items. Higher scores indicate greater severity of depression, with commonly accepted cutoffs being 0-7 (normal), 8-13 (mild depression), 14-18 (moderate depression), 19-22 (severe depression), and 23 or above (very severe depression).
