Citalopram is a selective serotonin reuptake inhibitor (SSRI) indicated for the treatment of depression. The study was presented at the American Psychiatric Association's annual meeting. "Across the four studies, 59 percent of patients treated with citalopram met the strictest therapeutic standard of complete and sustained remission, which means that there were no signs of depression," said Michael Thase, M.D., professor of psychiatry at the University of Pittsburgh School of Medicine. The full remission of symptoms after 20 weeks of therapy in the citalopram-treated patients far exceeded the standard description of full-sustained remission, which is defined by DSM-IV, psychiatry's diagnostic manual, as a period of at least two months in which there are no significant symptoms. Additionally, the evaluation of citalopram's efficacy in this analysis was substantially more rigorous than assessments sometimes used in clinical trials of antidepressants (e.g., 50 percent or more reduction in acute, short-term symptoms of patient response). "Full remission should be the goal of antidepressant therapy, rather than short-term response, because full remission is associated with better psychosocial functioning and reduces the risk of relapse," said Dr. Thase. "Most of the patients treated with citalopram in these four studies achieved full remission." A total of 810 patients with major depressive disorder (MDD) participated in the four studies, which were analyzed retrospectively. The studies included in-patients and out-patients from a range of age groups, with at least 230 patients age 65 or older. Treatments consisted of both open-label and double blind dosing with citalopram for periods ranging from 20 to 28 weeks. Across all four studies, an average of 59 percent of patients achieved remission, with sustained remission rates ranging from 53 to 72 percent in the studies. Citalopram was well-tolerated across all four trials. The side effects most commonly reported were headache, nausea, diarrhea and sleepiness. Citalopram has been shown to be safe and effective in many large-scale clinical trials involving patients with mild-to-moderate depression. Because citalopram has little or no potential to inhibit the metabolism of other drugs, it may be an especially useful antidepressant for older or medically complicated patients. As with all SSRIs, citalopram should not be taken together with monoamine oxidase inhibitors.
