Memantine in Bipolar Patients With Alcoholism

• Status: Unknown status
• Trial end date: 2017-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Since memantine may not only inhibit overactivity of microglial cell, but also repair the damaged neurons and neurogenesis through activation of astroglial cell and release of neurotrophic factors, the investigators propose that the neurotrophic effect of memantine may benefit neurodegenerative diseases including bipolar disorders (BP) and alcohol dependence. In the current study, the investigator will investigate whether add-on memantine at a dose of 5 mg/day has a beneficial effect on BP comorbid with alcohol dependence.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No
