Comparison between the Efficacies of Modafinil and Citalopram in the Treatment of Major Depression.

Abstract

Introduction: Antidepressants are the most common treatment for major depression. Also, psychotherapy is used for the treatment of depression. Tricyclic antidepressants are among the most frequently used medications to treat depression, with many known side effects. Therefore, checking and replacing other suitable drugs is essential in order to reduce side effects. Thus, the present study aimed to compare the efficacy of Modafinil and Citalopram in the treatment of patients with major depressive disorder. Methods:This interventional study was performed in 2019 on 30 people aged 18 to 65 years who had been diagnosed with a major depressive disorder based on DSM-5 criteria as well as the Hamilton Depression Rating Scale (HDRS), on which they got a score above 25. Subjects were randomly divided into two groups: the first group received Modafinil tablets (200 mg once daily, in the morning) and the second group Citalopram (20-40 mg/day). A Chi-square test was used to analyze the qualitative findings, and an independent t-test was used to compare quantitative data. Results:The results showed that changes in HDRS score were significant over time (P <0.05). The mean difference in HDRS scores was significant in all stages among the study subjects (P <0.05). However, there were no significant differences in HDRS scores between groups in terms of gender, age, marital status, education, occupation, and economic status, either before treatment or three and six weeks after treatment. Conclusion:This was the first comparative study of Modafinil and Citalopram efficacy in treating patients with major depressive disorder. Larger-scale, longer-term clinical trials, including long-term discontinuation trials and placebo-controlled parallel treatment studies, are further necessary. Also, a larger sample size with a placebo comparison is recommended.
