OBJECTIVE: Assess quetiapine plus lamotrigine (QTP+LTG) combination maintenance therapy effectiveness in challenging bipolar disorder (BD).
METHOD: Outpatients assessed with the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) Affective Disorders Evaluation and followed with the STEP-BD Clinical Monitoring Form were naturalistically prescribed QTP+LTG.
RESULTS: Fifty-four outpatients with challenging BD, taking in addition to QTP+LTG, a mean±SD of 2.1±1.6 (in 63.0% at least 2) other psychotropic and 2.3±1.9 non-psychotropic prescription medications, had QTP+LTG maintenance trials. Median(mean±SD) QTP+LTG duration was 401(730±756) days. Final QTP and LTG doses were 87.5(188±211) and 300(287±108) mg/day, respectively. Half (27/54) of patients discontinued QTP (in 19), LTG (in 6), or QTP+LTG (in 2), after 294(415±414) days - due to side-effects in 10, inefficacy in seven, non-adherence in five, and other reasons in five. 42.6%(23/54) had additional pharmacotherapy intervention for emergent mood symptoms, after 175(261±237) days, with at least one psychotropic added (in 16/54) or substantively (by ≥50%) increased (in 7/54). 55.6%(30/54) had recurrent mood episodes, after 126(187±158) days, most often depressive (in 35.2%), although 64.8%(35/54) were euthymic at final visit taking QTP+LTG. Sedation increased significantly during treatment among those with side-effect discontinuations, and 19.2%(10/52, all having QTP added to LTG) had clinically significant (≥7%) weight gain.
LIMITATIONS: No placebo comparison group. Small sample of predominantly female Caucasian insured outpatients taking complex concurrent medication regimens.
CONCLUSION: Additional studies are warranted to confirm our preliminary observation that QTP+LTG maintenance may be effective in patients with challenging BD.
