[Efficacy of fluvoxamine combined with extended-release methylphenidate on treatment-refractory obsessive-compulsive disorder].

Abstract

OBJECTIVE:

To observe the clinical efficacy of dopamine modulator methylphenidate (MPH) of extended-release formulations (MPH-ER) augmentation of ongoing fluvoxamine treatment in refractory obsessive-compulsive disorder (OCD) and its effects on patient's anxiety and sleep quality.
 Methods: A pilot randomized, placebo-controlled, and double-blind trial was conducted at an outpatient, single-center academic setting. Participants included 44 adults with serotonin reuptake inhibitor treatment-refractory OCD and they received a stable fluvoxamine pharmacotherapy with Yale-Brown Obsessive Compulsive Scale (Y-BOCS) scores higher than 20. The 44 patients were randomly assigned into a study group and a control group, with 22 patiencs in each group. Fluvoxamine and MPH-ER were given to the study group, while fluvoxamine and placebo were given to the control group, with 8 weeks of the treatment course. Y-BOCS, Hamilton Anxiety Scale (HAMA) were used to assess the efficacy, Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality, and Treatment Emergent Symptom Scale (TESS) was used to evaluate the side effects. Data were analyzed in the intention-to-treat sample.
 Results: The improvement in the Y-BOCS total score, Y-BOCS obsession subscale score and HAMA score were more prominent in the study group than those in the control group (P<0.001). There was no significant difference in PSQI score and TESS score between the two groups. MPH-ER was well tolerated.
 Conclusion: Fluvoxamine combined with MPH-ER is effective in the treatment of refractory obsessive-compulsive disorder. It can improve anxiety and has no adverse effect on sleep quality.
