Female Sexual Dysfunction in Patients Treated with Antidepressants: A Comparison between Agomelatine and Escitalopram

Aim: This study aims to determine and compare the prevalence of Female Sexual Dysfunction (FSD) between patients on escitalopram and agomelatine, as well as to investigate possible factors associated with their usage.

Study Design: Cross-sectional.

Place and Duration of Study: Psychiatric Day Care Clinic, Department of Psychological Medicine, University Malaya Medical Centre (UMMC), Malaysia, between November 1, 2020 until February 1, 2021.

Methodology: This study is a cross-sectional study involving 66 women with depression from the outpatient psychiatric clinic of a university hospital; 35 of whom were prescribed with escitalopram and 31 with agomelatine. The subjects were in remission and had no significant signs or symptoms of depression for at least 2 months. The prevalence of FSD between the two groups were compared after adjusting for underlying depression severity.

Results: This study showed that the overall prevalence rate of FSD was 33.3%, with the prevalence being higher for those on escitalopram (42.9%) than those on agomelatine (22.6%), but did not achieve statistical significance (P=0.081). Out of the six domains of FSD, multivariate analyses revealed that there was a significant reduction of 69% in sexual desire disorder (95% CI:0.110, 0.855), P=0.022 for those on agomelatine compared to escitalopram. Controlling for drug dosage and depression severity (as measured using Montgomery-Asberg Depression Rating Scale), the odds for patients on agomelatine developing sexual desire disorder was 0.267 (95% CI:0.091, 0.783), P=0.016.

Conclusion: There was no significant difference in FSD risk between patients on agomelatine and those on escitalopram. Patients on agomelatine were however less likely to develop sexual desire disorder, which demonstrates a slightly better sexual acceptability profile of agomelatine in women in this respect compared to escitalopram.
