Primary Outcome Measures:
  • Yale Brown Obsessive Compulsive Scale Modified for CB (CB-YBOCS) [ Time Frame: from study start to study end (8-weeks) and is Investigator rated ]
    The CB-YBOCS is a reliable and valid, 10-item, clinician-administered scale that rates buying symptoms within the last seven days, on a severity scale from 0 to 4 for each item (total scores range from 0 to 40 with higher scores reflecting greater illness severity). Scores ranging from 0 to 10 reflect minimal or mild symptoms; scores from 11 to 20 suggest moderate symptoms; severe symptoms are associated with scores from 21 to 30; and scores greater than 30 reflect extreme buying symptoms

Enrollment: 10
Study Start Date: December 2008
Study Completion Date: August 2010
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Memantine
10-30mg, memantine
Drug: Memantine
10-30mg, by mouth, daily
Other Name: Namenda

Detailed Description:
The goal of the proposed study is to evaluate the efficacy of memantine in the treatment of compulsive buying. Sixteen subjects meeting criteria for compulsive buying will receive 8 weeks of open-label memantine. The hypothesis to be tested is that memantine will be effective and well tolerated in patients with compulsive buying. The proposed study will provide needed data on the treatment of a disabling disorder that currently lacks a clearly effective treatment.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All

  3. history of seizures
  4. myocardial infarction within 6 months
  5. current pregnancy or lactation, or inadequate contraception in women of childbearing potential
  6. a need for medication other than memantine with possible psychotropic effects or unfavorable interactions;
  7. clinically significant suicidality;
  8. current Axis I disorder determined by the SCID and SCID-compatible modules for impulse control disorders, except for nicotine dependence
  9. lifetime history of bipolar disorder type I or II, dementia, schizophrenia, or any psychotic disorder determined by SCID
  10. current or recent (past 3 months) DSM-IV substance abuse or dependence;
  11. positive urine drug screen at screening
  12. initiation of psychotherapy or behavior therapy within 3 months prior to study baseline
  13. previous treatment with memantine
  14. treatment with investigational medication or depot neuroleptics within 3 months, with fluoxetine within 6 weeks, or with other psychotropics within 2 weeks prior to study baseline
