Vilazodone is a selective serotonin reuptake inhibitor and 5-HT receptor partial agonist approved for the treatment of major depressive disorder (MDD). This report summarizes the safety and tolerability of vilazodone 40 mg/day during short- and long-term treatment of adult MDD.
Pooled data from two 8-week, double-blind studies of vilazodone (n = 436) vs placebo (n = 433) and data from one 52-week, open-label study (n = 616, vilazodone only) were analyzed. Patients aged 18-70 with DSM-IV-TR-defined MDD received vilazodone or placebo (8-week studies only) once daily, with food, titrated to 40 mg/day over 2 weeks. Safety and tolerability assessments included adverse events (AEs), laboratory tests, vital signs, electrocardiograms, and weight.
The most common AEs in all studies were diarrhea, nausea, and headache. Vilazodone-associated AEs in the two 8-week studies, defined as an incidence rate of ≥5% in the vilazodone group and at least twice that for placebo, were diarrhea (28.0% vs 9.2%), nausea (23.4% vs 5.1%), and insomnia (6.0% vs 2.1%), with the majority reported as mild to moderate and <5% of those patients requiring concomitant (directed) treatment for these conditions. Discontinuation rates due to AEs were 7.1% (vilazodone) and 3.2% (placebo) in the 8-week studies and 20.7% in the 52-week study. Vilazodone had no clinically significant effects on vital signs, laboratory tests, or electrocardiograms.
Vilazodone 40 mg/day was well tolerated during short- and long-term MDD treatment in these trials. Safety profiles associated with 8- and 52-week exposure were consistent.
维拉唑酮是一种选择性5-羟色胺再摄取抑制剂和5-羟色胺受体部分激动剂,已被批准用于治疗重度抑郁症(MDD)。本报告总结了维拉唑酮40毫克/天在成年MDD患者短期和长期治疗中的安全性和耐受性。
分析了两项为期8周的维拉唑酮(n = 436)与安慰剂(n = 433)双盲研究的汇总数据以及一项为期52周的开放标签研究(n = 616,仅维拉唑酮)的数据。年龄在18至70岁、符合DSM-IV-TR定义的MDD患者每天一次服用维拉唑酮或安慰剂(仅8周研究),与食物同服,在2周内滴定至40毫克/天。安全性和耐受性评估包括不良事件(AE)、实验室检查、生命体征、心电图和体重。
在所有研究中,最常见的AE是腹泻、恶心和头痛。在两项8周研究中,与维拉唑酮相关的AE(定义为维拉唑酮组发生率≥5%且至少是安慰剂组的两倍)为腹泻(28.0%对9.2%)、恶心(23.4%对5.1%)和失眠(6.0%对2.1%),大多数报告为轻度至中度,<5%的患者需要针对这些情况进行联合(定向)治疗。在8周研究中,因AE导致的停药率为7.1%(维拉唑酮)和3.2%(安慰剂),在52周研究中为20.7%。维拉唑酮对生命体征、实验室检查或心电图无临床显著影响。
在这些试验中,维拉唑酮40毫克/天在MDD短期和长期治疗期间耐受性良好。与8周和52周暴露相关的安全性概况是一致的。
