BACKGROUND AND OBJECTIVE: Residual sleeping disturbances after improvement of depression in major depressed patients are associated with more functional problems, increased relapses and more risk of becoming resistant to treatment. The aim of this study was to compare the efficacy of gabapentin with clonazepam for treating residual sleeping disturbances. METHODS: This comparative trial was designed as a randomized, controlled, double-blind study. Sixty-three patients with a DSM-IV diagnosis of major depressive disorder (MDD) who had been treated with one of the selective serotonin reuptake inhibitors (SSRIs; fluoxetine, citalopram or sertraline) were included in the study. The patients' depression had improved [Hamilton Depression Rating Scale (HDRS) <10] but they were complaining of sleeping problems [Pittsburgh Sleep Quality Index (PSQI) >5; Insomnia Severity Index (ISI) >8]. Patients were randomized to receive a flexible dose of gabapentin (100-600 mg/day) or clonazepam (0.5-2 mg/day) beside their current antidepressant medication for a period of 4 weeks. Outcome measures were PSQI, ISI and Clinical Global Impression (CGI). RESULTS: Our results demonstrated that similar to the clonazepam group, sleeping problems improved significantly in the gabapentin group at the end of the trial (PSQI: P = 0.001, Z = 3.549; ISI: P = 0.001, Z = 3.347).The two groups did not show a significant difference in treating residual sleep disturbances (PSQI: P = 0.234, Z = 1.432; ISI: P = 0.456, Z = 1.347). CONCLUSION: This study revealed that gabapentin is comparable to clonazepam for treating sleeping problems associated with major depression.
