Objective: The authors evaluated the potential of methylphenidate to accelerate and enhance antidepressant response to citalopram in elderly depressed patients. Methods: Sixteen outpatients with major depression were treated in a 10-week double-blind trial. Response was defined as a score on the Hamilton Depression Rating Scale (24-item) of less than 10. Results: An accelerated response was observed by week 3 in five subjects receiving citalopram (CIT) + methylphenidate (MPH) and in none of those receiving CIT + placebo (PBO). Subjects receiving citalopram and methylphenidate showed a significant improvement in depressive symptoms compared with those on citalopram and placebo. Conclusion: Combined treatment with citalopram and methylphenidate appears to be a viable strategy for accelerating and enhancing antidepressant response in elderly depressed patients limited by tolerability and safety.
