Objectives: The objective of the study was to compare the two antidepressant drugs citalopram and escitalopram on the basis of efficacy in depressed patients of Hepatitis C patients receiving interferons.
Methods: In this double blind randomized trial, the hepatitis C patients visited National institute of liver and Gastro intestinal diseases (NILGID), Dow University Hospital, were screened for depression before starting treatment with interferons. The Institutional review board approval was obtained and its letter reference no.is: IRB-682/DUHS/Approval/2016/169. Patients with previous history of depression were excluded from the study. The patients who started with Interferon therapy were assessed for depression on baseline and then on each visit. Those who developed depression were randomly assigned to receive either citalopram or escitalopram. Treatment groups were assessed with depression scale each time they visit the clinic. Two antidepressants were compared for their efficacy at an interval of 4 weeks, 8weeks and then 12 weeks.
Results: In the current study 80 patients were randomized to receive either citalopram or escitalopram. The study outcome was better in patients treated with escitalopram. The mean change in depression score from baseline to the end of the study was greater in escitalopram group i.e. 10.41 as compared to citalopram group i.e. 14.17. The difference in depression score was also calculated as 4.28 and.3.76 (p < 0.001) for both the drugs at week 8 and week 12 respectively, which was statistically significant. Difference in depression score were also calculated for gender 0.576 (p = 0.497) and age 0.950 (p = 0.265), which were found to be non-significant, statistically.
Conclusion: The results demonstrated superiority of escitalopram over citalopram, the drug is twice as potent as the racemic mixture. Additionally the drug is well tolerated and exhibited better effects. Escitalopram proved to be a safer alternative to citalopram.
