Low Dose Amisulpride Vs Olanzapine-Fluoxetine Combination in Post-Schizophrenic Depression

Post-Schizophrenic Depression (PSD) increases the morbidity and mortality of Schizophrenic patients. Hence, it warrants early assessment and intervention. But, clinical trials on PSD are very few. However, an Antipsychotic with an adjunctive Antidepressant (like Olanzapine-Fluoxetine Combination) is the commonly prescribed treatment in PSD. Low dose Amisulpride (\<400 mg/day) which is effective against the negative symptoms of Schizophrenia has also proved efficacious in treating depression in non-psychotic conditions, but its antidepressant property has never been studied in PSD. This is an 8-week, randomized, parallel-group study that will explore the efficacy and safety of low-dose Amisulpride versus Olanzapine-Fluoxetine Combination in the treatment of PSD. Our hypothesis is that low dose Amisulpride has better efficacy and safety versus Olanzapine-Fluoxetine Combination in PSD, after 8-weeks.
