Sahraian A, Ghanizadeh A, Kazemeini F - Trials (2015)

Bottom Line: We also checked for the presence of adverse effects.Adding vitamin C to citalopram did not increase the efficacy of citalopram in MDD patients.Vitamin C plus citalopram is as effective as placebo plus citalopram for treating adult patients with suicidal behavior.

ABSTRACT

Background: There are some animal studies suggesting the possible role of vitamin C for treating depression. However, the efficacy of vitamin C for treating adult patients with major depressive disorder (MDD) has never been examined.

Methods: This 8-week randomized double-blind placebo-controlled clinical trial included adult patients with major depressive disorder according to DSM-IV diagnostic criteria. Twenty-one patients in the treatment group received citalopram plus vitamin C and the 22 patients in the control group received citalopram plus placebo. The Hamilton Depression Rating Scale was used to measure depressive symptoms at baseline, week 2, week 4, and week 8. We also checked for the presence of adverse effects.

Results: While depression symptoms decreased in both groups during this trial, there was no statistically significant difference between the 2 groups (P = .5). The rate of remission, partial response, and complete response was not different between the two groups. The rate of adverse effects were not different between the two groups.

Conclusion: Adding vitamin C to citalopram did not increase the efficacy of citalopram in MDD patients. Vitamin C plus citalopram is as effective as placebo plus citalopram for treating adult patients with suicidal behavior. No serious adverse effect for this combination was identified during this trial.

Mentions: The mean (SD) scores of HDRS are displayed in Table 1. The HDRS score was not different between the two groups at baseline. Repeated measure of ANOVA showed that the HDRS score significantly decreased during this trial in both groups (F(3,120) = 154.6, P < 0.001) (Figure 2). However, the interaction of time and group (time × group) was not statistically different (F(3,120) = .57, P = .6). In other words, the behavior of the two treatments was similar across time. In addition, repeated measure ANOVA showed that there was no statistical difference between the 2 groups (F(1,40) = .33, P = .5). Additionally, the difference between the 2 groups was similar at the endpoint (t = −.3, df = 41, P = .6).Figure 2
