Major depressive disorder, antidepressants, and sexual dysfunction
ABSTRACT Sexual dysfunction is a common problem with a number of causes, including psychosocial factors, general medical illness, psychiatric disorders, and psychotropic and nonpsychiatric medications. It is especially prevalent among patients with poor emotional health and has been strongly associated with antidepressant medications. Selective serotonin reuptake inhibitors (SSRIs) in particular have demonstrated a higher incidence of sexual dysfunction than other antidepressants that work through different mechanisms of action. Further supporting the relationship between sexual dysfunction and antidepressant mechanism of action, data from a number of studies indicate that bupropion, nefazodone, and mirtazapine alleviate symptoms of sexual dysfunction and are as effective as SSRIs at controlling depressive symptoms. Although a number of strategies besides drug substitution have been utilized to help manage antidepressant-induced sexual dysfunction, many patients remain suboptimally treated; as many as 42% of patients were found to passively wait for spontaneous remission. The addition of antidotal therapy has been proven to be among the effective management strategies for sexual dysfunction. However, due to a lack of systematic data, additional studies are warranted to further investigate these findings.

- "Further studies suggest that some of the antidepressants lead to impairment in the sexual functioning in all the phases of the sexual cycle. Lower rates of sexual dysfunction (range 0-24%) have been reported with antidepressants like mirtazapine, reboxetine, bupropion and moclobemide. Studies have also shown that besides antidepressants many other factors influence the incidence and prevalence of sexual dysfunction in patients with depression. "
ABSTRACT: To study the prevalence and patterns of sexual dysfunctions in female patients receiving antidepressants. Eighty married female patients with a diagnosis of depressive disorder, currently in remission, and receiving a single antidepressant at least for 3 months, were assessed for sexual dysfunction on female sexual function index (FSFI) scale. Thirty four patients (42.5%) receiving antidepressants had FSFI score less than 26.55 and were considered to have sexual dysfunction. When only the domain cutoff scores were used for the whole study sample (n=80), it was found that 95% had decreased desire, 60% had decreased arousal, 37.5% had decreased lubrication, 63.8 had decreased orgasm, 55% had decreased satisfaction and 25% had pain during sexual activity. To conclude, our study suggests that sexual dysfunction is quite prevalent in married female patients receiving antidepressants and all the domains of sexual functioning are impaired by antidepressants.Journal of Pharmacology and Pharmacotherapeutics 07/2012; 3(3):259-65.

- "appears to be related to increased activation of 5 - HT 2 receptors in response to increased 5 - HT signaling ( Clayton and Montejo , 2006 ; Serretti and Chiesa , 2009) . Another notable finding is that although this was a short - term study and was not designed specifically to assess the effects of amitifadine on weight , amitifadine was not associated with any weight changes .

ABSTRACT: Amitifadine (EB-1010, formerly DOV 21,947) is a serotonin-preferring triple reuptake inhibitor with a relative potency to inhibit serotonin, norepinephrine, and dopamine uptake of ∼1:2:8, respectively. This 6-week, multicenter, randomized, double-blind, parallel, placebo-controlled study evaluated the efficacy and tolerability of amitifadine in 63 patients with major depressive disorder. Eligible patients (17-item Hamilton Depression Rating Scale [HAMD-17] ≥ 22 at baseline) were randomized to amitifadine 25 mg twice daily (BID) for 2 weeks, then 50 mg BID for 4 weeks or placebo. Mean baseline scores in the modified intent-to-treat population (n = 56) were 31.4 for the Montgomery-Åsberg Depression Rating Scale (MADRS), 29.6 for the HAMD-17, and 25.4 for the Derogatis Interview for Sexual Functioning - Self Report (DISF-SR). At the end of the 6-week double-blind treatment, estimated least squares mean change from baseline (mixed-model repeated measures [MMRM]) in MADRS total score was statistically significantly superior for amitifadine compared to placebo (18.2 vs. 22.0; p = 0.028), with an overall statistical effect size of -0.601 (Cohen's d). Amitifadine also was statistically significantly superior to placebo (p = 0.03) for the Clinical Global Impression of Change - Improvement. An anhedonia factor score grouping of MADRS Items 1 (apparent sadness), 2 (reported sadness), 6 (concentration difficulties), 7 (lassitude), and 8 (inability to feel) demonstrated a statistically significant difference in favor of amitifadine compared to placebo (p = 0.049). No differences were observed between treatments in DISF-SR scores. Amitifadine was well-tolerated. Two patients on each treatment discontinued the study early due to adverse events; however, no serious adverse events were reported. This initial clinical trial in patients with severe major depression demonstrated significant antidepressant activity with amitifadine, including attenuating symptoms of anhedonia, and a tolerability profile that was comparable to placebo. The efficacy and tolerability of amitifadine for major depressive disorder are being investigated in additional clinical trials.Journal of Psychiatric Research 09/2011; 46(1):64-71.

ABSTRACT: Sexual side effects of antidepressant medications are far more common than initially reported, and their scope, quality, and duration remain poorly captured in the literature. Antidepressant treatment emergent sexual dysfunctions may decrease clients’ quality of life, complicate psychotherapy, and damage the treatment alliance. Potential damage to the treatment alliance is greatest when clients have not been adequately informed of risks related to sexual side effects. It had previously been assumed that sexual side effects always resolve shortly after medications are discontinued. Emerging evidence, however, suggests that in some individuals, sexual dysfunction side effects may persist indefinitely. The authors argue that all psychologists should be well-informed about sexual side effects risks of antidepressant medications, should routinely conduct a pre-medication baseline assessment of sexual functioning, and take an active role in the informed consent process.Journal of Contemporary Psychotherapy 06/2008; 39(2):135-143.
