fluvoxamine and Borderline-Personality-Disorder

The aim of the study is to test whether fluvoxamine affects the function of the hypothalamic pituitary adrenal (HPA) axis in female borderline (borderline personality disorder, BPD) patients with and without a history of sustained childhood abuse. Special attention is given to the presence of comorbid major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). The HPA axis of 30 female BPD patients with (n = 17) and without (n = 13) a history of sustained childhood abuse was challenged with a combined dexamethasone and corticotropin releasing hormone test (DEX/CRH test) before and after 6 (n = 14) and 12 (n = 16) weeks of fluvoxamine treatment (150 mg/day). Both 6- and 12-week fluvoxamine treatments were associated with a significant and robust reduction of the adrenocorticotrophic hormone (ACTH) and cortisol response to the DEX/CRH test. The magnitude of the reduction was dependent on the presence of sustained childhood abuse, but not on the presence of comorbid MDD or PTSD: patients with a history of sustained childhood abuse showed the strongest reduction in ACTH and cortisol. In conclusion, Fluvoxamine treatment reduces the hyperresponsiveness of the HPA axis in BPD patients with a history of sustained childhood abuse. This effect is likely to be obtained in the first 6 weeks of treatment.

Selective serotonin reuptake inhibitors (SSRIs) are recommended for treatment of affect lability, impulsivity, and aggression in patients with borderline personality disorder. This recommendation is based on positive findings in at least 10 open studies and one small double-blind study of SSRIs for patients with borderline personality disorder and one study of impulsive aggressive patients with different personality disorders. A randomized, placebo-controlled SSRI study with borderline personality disorder patients, however, provided inconclusive results because of a large response to placebo. It was, therefore, decided to conduct a new randomized trial with a larger study group.. A double-blind, placebo-controlled, randomized trial using the SSRI fluvoxamine for 6 weeks followed by a blind half-crossover for 6 weeks and an open follow-up for another 12 weeks was conducted with 38 nonschizophrenic, nonbipolar female patients with borderline personality disorder. The outcome measures were the rapid mood shift, impulsivity, and aggression subscales from the Borderline Personality Disorder Severity Index.. Fluvoxamine but not placebo produced a robust and long-lasting reduction in the scores on the subscale for rapid mood shifts. In contrast, no difference between the fluvoxamine and placebo groups was observed in the effect on the impulsivity and aggression scores.. In this study, fluvoxamine significantly improved rapid mood shifts in female borderline patients, but not impulsivity and aggression. This latter finding may be due to gender-specific differences in impulsivity and aggression.

In 3 patients the addition of fluvoxamine to a constant dosage of carbamazepine (CZP) caused a substantial rise of plasma CZP accompanied by symptoms of intoxication. As this drug combination may occur increasingly in the future, this probably pharmacokinetic interaction is of practical relevance.
