The involvement of the multi-drug-resistant 1 P-glycoprotein gene (MDR1 P-gp) in the transport of antidepressants across the blood-brain barrier makes it a good candidate for the prediction of antidepressant response and side effects. We investigated the role of the MDR1 P-gp gene in predicting the induction of mania in bipolar patients (BP) treated with proserotonergic drugs. Participants met the DSM-IV criteria for BP or BPII and had at least one depressive episode treated with proserotonergic antidepressants. The first group (n=26) included patients with at least one DSM-IV manic/hypomanic episode developed during antidepressant treatment; the second group (N=29) included patients with no antidepressant-induced switches. The common polymorphism of the MDR1 was genotyped for both groups and comparison was made with respect to the presence/absence of induced mania between the two groups. No association between antidepressant-induced mania and the MDR1 alleles or genotypes was found (chi2=1.85, 2 df, P=0.39; chi2=0.13, 1 df, P=0.72).
