Brief Summary:
This is a ten-week, double-blind study of Wellbutrin XL in outpatients with dysthymic disorder, a form of low-grade chronic depression. We hypothesize that patients taking Wellbutrin XL will show greater improvement in depression symptoms and psychosocial functioning than patients taking placebo.

Condition or disease Intervention/treatment Phase
Dysthymic Disorder Drug: bupropion XL Other: Placebo Phase 4

Detailed Description:
This is a ten-week, double-blind, placebo-controlled study designed to evaluate the tolerability, dosing and efficacy of Wellbutrin XL in outpatients who meet Diagnostic and Statistical Manual-IV criteria for early onset, primary type dysthymic disorder (low-grade chronic depression). It is hypothesized that patients taking Wellbutrin XL will show greater improvement in depression symptoms and psychosocial functioning than patients taking placebo.

Experimental: bupropion XL
Treatment with active medication (bupropion XL) dose ranging from 150 to 450 mg/day

Primary Outcome Measures :
  1. Hamilton Depression Rating Scale, 24 Items (HDRS) [ Time Frame: 10 weeks ]

    Widely used depression rating scale, with higher scores reflecting greater level of depression. Assesses suicidality which is a safety issue.

    This study used the 24 item version of the Hamilton Depression Rating Scale; item scores range from 0 to 4 on some items, 0 to 2 or 0 to 3 on other items; range of total score = 0 to 75, with higher score indicating worse depression Response (>50% decrease) Remission (score<=7)

Secondary Outcome Measures :
  1. Cornell Dysthymia Rating Scale (CDRS) [ Time Frame: 10 weeks ]
    A 24 item scale assessing symptoms of chronic depression. Scores from 0 to 96 with higher score indicating worse depression

  2. Beck Depression Inventory (BDI) [ Time Frame: 10 weeks ]
    21 item patient rated assessment of depression symptoms, with item scores ranging from 0 to 3. Total BDI scores can range from 0 to 63, with higher scores indicating worse depression.

  3. Clinical Global Improvement (CGI) [ Time Frame: 10 weeks ]
    A global assessment of patient improvement, ranging from 1 (very much improved) to 7 (very much worse)

  4. Global Assessment of Functioning Scale (GAFS) [ Time Frame: 10 weeks ]
    A clinician rated assessment of patient's overall functioning, ranging from 0 (severely impaired) to 100 (excellent functioning)
