Efficacy and mood conversion rate during long-term fluoxetine v. lithium monotherapy in rapid- and non-rapid-cycling bipolar II disorder.

ABSTRACT:

Background

Controversy exists over antidepressant use in rapid-cycling bipolar disorder.

Aims

Exploratory analysis of safety and efficacy of fluoxetine v. lithium monotherapy in individuals with rapid- v. non-rapid-cycling bipolar II disorder.

Method

Randomised, double-blind, placebo-controlled comparison of fluoxetine v. lithium monotherapy in patients initially stabilised on fluoxetine monotherapy (trial registration NCT00044616).

Results

The proportion of participants with depressive relapse was similar between the rapid- and non-rapid-cycling groups (P = 0.20). The odds of relapse were similar between groups (P = 0.36). The hazard of relapse was similar between groups (hazard ratio 0.87, 95% CI 0.40-1.91). Change in mania rating scores was similar between groups (P = 0.86). There was no difference between groups in the rate of syndromal (P = 0.27) or subsyndromal (P = 0.82) hypomania.

Conclusions

Depressive relapse and treatment-emergent mood conversion episode rates were similar for lithium and fluoxetine monotherapy and placebo during long-term, relapse-prevention therapy of rapid- and non-rapid-cycling bipolar II disorder.

Project description:AimsRapid-cycling bipolar disorder is difficult to treat and associated with greater morbidity than non-rapid-cycling disease. This post hoc analysis evaluated 28 patients with rapid-cycling bipolar I disorder from a 100-week, double-blind, placebo-controlled study assessing long-term efficacy, safety and tolerability of aripiprazole in patients with bipolar I disorder (most recently manic/mixed).MethodsFollowing >or= 6 consecutive weeks' stabilisation with open-label aripiprazole, patients were randomised (1 : 1) to aripiprazole or placebo. Patients completing 26 weeks treatment without relapse could continue for a further 74 weeks. Primary end-point was time to relapse for manic, mixed or depressive symptoms, defined as discontinuation due to lack of efficacy. Safety assessments included adverse event (AE) monitoring and changes in weight and lipid, glucose and prolactin levels.ResultsOf the 28 patients (aripiprazole, n = 14; placebo, n = 14) with rapid-cycling bipolar disorder, 12 (aripiprazole, n = 7; placebo, n = 5) completed the initial 26-week treatment period and three (all aripiprazole treated) completed the 100-week, double-blind period. Time to relapse was significantly longer with aripiprazole vs. placebo at week 26 [log-rank p = 0.033; 26-week hazard ratio = 0.21 (95% CI: 0.04, 1.03)] and week 100 [log-rank p = 0.017; 100-week hazard ratio = 0.18 (95% CI: 0.04, 0.88)]. The most commonly reported AEs with aripiprazole during the 100 weeks (>or= 10% incidence and twice placebo) were anxiety (n = 4), sinusitis (n = 4), depression (n = 3) and upper respiratory infection (n = 3). One aripiprazole-treated patient discontinued due to an AE (akathisia). There were no significant between-group differences in mean changes in weight or metabolic parameters.ConclusionIn this small, post hoc subanalysis, aripiprazole maintained efficacy and was generally well tolerated in the long-term treatment of rapid-cycling bipolar disorder. Further research with prospectively designed and adequately powered trials is warranted.
