PURPOSE/OBJECTIVES: To identify appropriate strategies for pharmacotherapeutic agents in the management of pain in older adults with cancer.
PubMed literature searches, personal reference collection, and clinical experience.
To make good decisions about pain management when developing treatment plans for older adults, healthcare providers should focus on the pharmacokinetic and pharmacodynamic properties of drugs in the context of the physiologic changes that occur with aging.
Unrelieved pain can have a detrimental effect on older adults; conversely, overmedicating can lead to an increased risk of adverse events. With advancing age, physiologic changes alter the pharmacokinetic and pharmacodynamic properties of drugs by reducing their absorption, changing their distribution, and modifying their metabolism and elimination. Also, common comorbidities increase the risk of pharmacologic toxicity and narrow the therapeutic window. In addition, polypharmacy-an issue more common in older adults-increases the complexity of prescribing and risk of adverse events. Consequently, older adults require individualization of their pharmacotherapies. Healthcare providers should consider carefully the risks and benefits of nonsteroidal anti-inflammatory drugs, opioids, and adjuvants before initiating an analgesic trial. The 2009 guidelines published by the American Geriatrics Society described several key principles for prescribing analgesics to older adults and offered specific recommendations and caveats for each drug class.
Current guidelines support appropriate management of cancer pain in older adults with specific recommendations for each class of analgesics as well as general prescribing principles.

在为老年人制定治疗计划时,为了对疼痛管理做出明智的决策,医疗保健提供者应在衰老过程中发生的生理变化的背景下,关注药物的药代动力学和药效学特性。
未缓解的疼痛会对老年人产生不利影响;相反,用药过量会导致不良事件风险增加。随着年龄的增长,生理变化会通过减少药物吸收、改变药物分布以及改变药物代谢和消除来改变药物的药代动力学和药效学特性。此外,常见的合并症会增加药物毒性风险并缩小治疗窗口。此外,多重用药(这在老年人中更为常见)会增加处方的复杂性和不良事件风险。因此,老年人需要个体化的药物治疗。医疗保健提供者在开始镇痛试验之前,应仔细考虑非甾体抗炎药、阿片类药物和辅助药物的风险和益处。美国老年医学会2009年发布的指南描述了为老年人开镇痛药的几个关键原则,并针对每类药物提供了具体建议和注意事项。
