As with prescribing or continuing medications, deprescribing brings with it the potential for harm as well as benefit. Uncertainty and avoidance of harm has been reported as a barrier to deprescribing in practice and may contribute to continuation of inappropriate medications.
This narrative review covers four main safety concerns/potential harms of deprescribing in older adults: adverse drug withdrawal events, return of medical condition(s), reversal of drug-drug interactions and damage to the doctor-patient relationship. These are discussed in relation to medications in general, with some examples of medication classes used to illustrate the potential safety concerns. The majority of these harms can be minimized or even prevented by using a patient-centered, structured deprescribing process with planning, tapering and close monitoring during, and after medication withdrawal.
More research is needed into the safety concerns of deprescribing, however, avenues exist during drug development and post-marketing surveillance to gain knowledge on this topic. Questions remain about when it is suitable to discontinue certain medications/medication classes and there is uncertainty about the harms and benefits of both medication continuation and discontinuation in complex older adults.
与开处方或持续用药一样,减药既有潜在益处,也有潜在危害。据报道,不确定性和对危害的规避是实践中减药的障碍,可能导致不适当药物的持续使用。
本叙述性综述涵盖老年人减药的四个主要安全问题/潜在危害:药物戒断不良事件、病情复发、药物相互作用的逆转以及医患关系的损害。这些问题将结合一般药物进行讨论,并列举一些药物类别实例来说明潜在的安全问题。通过采用以患者为中心的结构化减药流程,在停药期间和停药后进行规划、逐渐减量和密切监测,这些危害中的大多数可以降至最低甚至预防。
需要对减药的安全问题进行更多研究,然而,在药物研发和上市后监测过程中存在获取该主题知识的途径。关于何时适合停用某些药物/药物类别仍存在疑问,对于复杂老年患者继续用药和停药的危害与益处也存在不确定性。
