In a randomized double-blind placebo-controlled study of memantine combined with fluoxetine published by Ghaleiha et al. In this open-label augmentation trial of memantine in treatment-resistant OCD, almost half the subjects had a meaningful improvement in symptoms. eCollection 2020.

Prior treatment resistance and the proximity between symptomatic improvement and the initiation of memantine point to its possible attenuating effect on the symptoms of OCD. Clipboard, Search History, and several other advanced features are temporarily unavailable. Newer medications that act on this NMDA receptor are under development. The reason for the differences between the results of our study and the two other studies on memantine was primarily because unlike most of the previous trials, the patients in our trial were not treatment-resistant.

Question. However, because this meta-analysis included only three small-sized RCTs (number of patients: 32–42), future studies using a larger sample size should be conducted to obtain more robust results. At her presentation, oral clomipramine was initiated and titrated to 300 mg/day; however, 10 weeks later, there was no significant clinical improvement (Yale-Brown Obsessive Compulsive Scale [4] score=35).

The increasing evidence for the involvement of the glutamatergic system in the pathophysiology of obsessive-compulsive disorder (OCD) has led to trials of agents such as N -acetylcysteine, riluzole, and d -cycloserine. Ms. A, a 34-year-old woman, was seen with incapacitating ego-dystonic obsessions, including fear of harm to her daughter and of losing her mind.

In a randomized double-blind placebo-controlled study of memantine combined with fluoxetine published by Ghaleiha et al. Posted by 1 month ago. Mean baseline Y-BOCS score was 27.4 (SD, 5.0). Memantine, an N-methyl-D-aspartate receptor antagonist, appears to reduce glutamate excitability and improve impulsive behaviors, suggesting it may help individuals with CB. The previ- In pediatric OCD patients, the glutamate caudate concentration was abnormally increased, but it decreased after paroxetine treatment (3). We report on the first open-label study to test the hypothesis that memantine, a noncompetitive glutamate antagonist, will result in a clinically meaningful reduction in OCD symptoms in adults with treatment-resistant OCD. Future randomized double-blind placebo-controlled trials are warranted. Treatment should only be continued if beneficial effects are seen. Quetiapine augmentation of SRIs in treatment refractory obsessive-compulsive disorder: a double-blind, randomised, placebo-controlled study [ISRCTN83050762]. Specifically, in 4 randomized controlled trials (RCTs), the response rate was 81% in 67 memantine-treated patients vs only 19% in 68 placebo-treated patients. 2020 Jul;35(4):173-193. doi: 10.1097/YIC.0000000000000314. “The key finding of the present study was that neither adjuvant gabapentin nor adjuvant memantine had better effects on symptoms of OCD than a placebo,” said the researchers.

Memantine as an Augmenting Agent for Severe Pediatric OCD TO THE EDITOR: The present case study is a follow-up to a previous case report (1), published in the Journal, on effective augmentation of the glutamatergic agent memantine to treat severe adult obsessive compulsive disorder (OCD). Our case suggests that memantine may be an option for treatment-resistant OCD, but controlled studies are needed to substantiate this observation. Memantine can help with decreasing the symptoms of OCD but not on its own. We report a therapeutic effect of add-on memantine, an N-methyl-d-aspartic acid glutamatergic receptor antagonist, in treatment-resistant OCD. 2, No. CONCLUSIONS: This study provides preliminary supportive evidence for the effectiveness of memantine as a glutamatergic augmenting agent in severe OCD.
