A comparative prospective open label randomized controlled 8 week study in patients of depression treated with vilazodone and sertraline

Background: Depression is a mood disorder treated with various antidepressant such as SSRIs due to lesser toxicity and improved safety profile.Methods: This was an eight week randomised active controlled parallel group study. 54 patients were allocated in two group. Group A received vilazodone while group B received sertraline. Assessment done at baseline, 2, 4 and 8 weeks on the basis of clinical efficacy, sexual dysfunction, side effects and weight gain using Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), Arizona Sexual Experience Scale (ASEX) and UKU Side Effect Rating Scale.Results: HAM-D score of group A was 18.78±1.78 and 7.67±1.66 while in group B was 19.04±2.12 and 8.15±1.77 at baseline and 8 weeks respectively. HAM-A score of group A was 15.44±1.50 and 6.63±1.39 while in group B was 15.26±1.83 and 7.07±1.14 at baseline and 8 weeks. ASEX total score of group A was 15.63±1.28 and 14.63±1.33 while group B was 15.52±1.37 and 16.41±1.12 at baseline and 8 weeks. ASEX desire score of group A was 9.63±0.93 and 8.67±0.88 while of group B was 9.59±0.93 and 10.07±0.92 at baseline and 8 weeks. UKU side effect rating at 2 and 8 weeks of group A was 0.22±0.42, 1.04±0.76 while in group B was 0.37±0.49, 1.89±0.85.Conclusions: Vilazodone and Sertraline are equally efficacious in treatment of depression and associated anxiety. When side effect profile were compared Vilazodone is found superior to Sertraline

Vilazodone for the Treatment of Depression: An Update / 전남의대학술지

Vilazodone is a novel antidepressant having a selective serotonin (5-HT) reuptake inhibitor and 5-HT(1A) receptor partial agonist profile, so it has been regarded as a serotonin partial agonist-reuptake inhibitor (SPARI). We aimed to provide Vilazodone's clinical implications mainly by reviewing published clinical trials. Vilazodone has been speculated to have three potential benefits including faster onset of action, greater efficacy, and better tolerability owning to its SPARI properties. However, no studies conducted so far have directly proven the above speculations. Five initial phase II trials failed to distinguish vilazodone from placebo in the treatment of MDD, but 4 randomized clinical trials (RCT), 3 post-hoc or pooled analysis, 1 long-term open label study, and a meta-analysis showed vilazodone's superior efficacy over placebo. The studies also showed vilazodone is generally safe and tolerable. However, diarrhea, nausea, headache, dizziness, dry mouth, and insomnia warrant close attention in clinical practice because they have been constantly noted throughout the clinical studies. 2 RCTs recently documented the efficacy and safety of vilazodone in patients with generalized anxiety disorder, which could be a start of broadening vilazodone's usage or FDA approval in diverse anxiety disorders.

Vilazodone for the Treatment of Major Depressive Disorder: Focusing on Its Clinical Studies and Mechanism of Action

We tried to review and update clinical and preclinical studies evaluating vilazodone's role as an antidepressant for patients with major depressive disorder (MDD). In terms of its mechanism of actions, we sought to elaborate them mainly through preclinical animal studies. A data search was conducted in November 1, 2013, using the key terms "vilazodone" or "Viibryd," in PubMed and Medline databases. All published and unpublished studies are included and citations from publications were also reviewed for additional references. Five unpublished, phase-II and two pivotal published phase-III clinical trials with nearly identical design (8-week, double-blind, randomized, and placebo-controlled) investigated efficacy of vilazodone, were found for the treatment of patients with MDD. Two post-hoc studies and one long-term open study were also included. Data were thoroughly reviewed to incorporate the pharmacology, action mechanism, efficacy and safety for the vilazodone in the treatment of major depressive disorder. Vilazodone is an antidepressant with novel mechanism of action because its chemical structure is unrelated to conventional antidepressant, and it has a selective serotonin (5-HT) reuptake inhibitor and 5-HT1A receptor partial agonist profile. Vilazodone is an effective and safe treatment option with its novel action mechanisms for patients with depression. Its putative benefits compared with other antidepressants must be thoroughly studied in adequately-powered and well-designed future clinical trials.
