Patients with ADHD may have better adherence to treatment with modified-release methylphenidate (MPH-MR) formulations, which are taken once daily, compared with immediate-release (IR) formulations, which need to be taken several times a day. Data on long-term outcomes such as adherence may be lacking from randomised controlled trials as these are usually only short-term. Observational studies, if performed and reported appropriately, can provide valuable long-term data on such outcomes, as well as additional information on effectiveness and efficiency, from a real-life setting. By reviewing previous observational studies that have investigated switching treatment from MPH-IR to MPH-MR, results from a new, naturalistic observational study, the OBSEER study, are put into context. We conclude that, based on observational trial data, switching from MPH-IR to MPH-MR is a valid clinical approach, with the potential for improved clinical outcome and treatment adherence.
患有注意缺陷多动障碍(ADHD)的患者每日服用一次的缓释型哌醋甲酯(MPH-MR)制剂,其治疗依从性可能优于需要每日多次服用的即刻释放(IR)制剂。由于随机对照试验通常仅为短期试验,因此可能缺乏关于依从性等长期结局的数据。如果进行并适当报告观察性研究,则可以从现实环境中提供有关此类结局的有价值的长期数据,以及关于有效性和效率的其他信息。通过回顾先前研究过从 MPH-IR 转换为 MPH-MR 治疗的观察性研究,将新的自然观察性研究 OBSEER 研究的结果置于上下文中。我们的结论是,基于观察性试验数据,从 MPH-IR 转换为 MPH-MR 是一种有效的临床方法,有可能改善临床结局和治疗依从性。
