Randomized Controlled TrialA double-blind, randomized, placebo-controlled prophylaxis trial of oxcarbazepine as adjunctive treatment to lithium in the long-term treatment of bipolar I and II disorder.
We evaluated the prophylactic efficacy and the long-term tolerability of oxcarbazepine administration in the treatment of bipolar I and II disorder as an adjunctive therapy to lithium. We conducted a 52-wk, double-blind, randomized, placebo-controlled, parallel-group, multicentre, clinical trial. Bipolar I and II DSM-IV outpatients, having had two or more episodes in the last year, but currently being in remission, were randomly assigned on a 1:1 ratio to oxcarbazepine (n=26) or placebo (n=29) as adjuncts to ongoing treatment with lithium. ⋯ Impulsivity was significantly better prevented by oxcarbazepine (p=0.0443). Overall, oxcarbazepine was well tolerated. This pilot, randomized clinical trial, suggests that oxcarbazepine might have some prophylactic efficacy with regards to impulsivity and perhaps mood episodes in patients taking lithium, although further, adequately powered controlled trials are needed to confirm these findings.
