Antidepressant-Induced Sexual Dysfunction: A comparison between Duloxetine and Escitalopram.

ABSTRACT

Background: Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs) have the potential to produce delayed ejaculation in men, delayed orgasm or anorgasmia in women and decreased libido that is independent of the gender. The occurrence of medication-associated sexual dysfunction increases the likelihood of medication non-compliance (or non-adherence) in patients, which may contribute to untreated depression and/or disease relapse. Materials & Methods: 60 patients with diagnosis of Depressive episode (in remission at the time of study), divided into 2 groups of 30 patients taking Duloxetine and the remaining 30 patients taking Escitalopram, were recruited on consecutive basis from the patients attending Psychiatry OPD of Lady Hardinge Medical College (LHMC). Each subject was rated on Arizona Sexual Experience Scale (ASEX) and the results obtained were statistically analyzed. Results: In the present study the average ASEX score obtained in the Escitalopram group (12.63) was found to be more than that in Duloxetine group (12.36), though this difference was not found to be statistically significant. Conclusions: These results illustrate that antidepressant-induced sexual dysfunction is reported frequently by patients taking SSRIs or SNRIs. Our study did not find any significant difference between escitalopram and duloxetine with respect to their sexual dysfunction profile but in view of the limitations of our study there is need for further research in this domain of psychopharmacology.
