Potential Drug-Drug and Herb-Drug Interactions in Patients With Cancer: A Prospective Study of Medication Surveillance
https://doi.org/10.1200/JOP.2017.020859
Abstract
Purpose:
Patients with cancer frequently use herbal supplements and concomitant medications along with antineoplastic agents. These patients are at high risk of herb-drug interactions (HDIs) and drug-drug interactions (DDIs). We aimed to determine clinically relevant DDIs and HDIs leading to pharmaceutical intervention. 癌症患者经常在抗癌治疗期间同时使用草药和其它药物。这些患者处于药物交互作用(草药-药物;药物-药物)的高风险中。此项前瞻性研究力图确定临床相关的药物交互作用导致医疗干预的情况。
Methods:
Patients starting a new anticancer therapy were asked to complete a questionnaire to identify concomitant use of any over-the-counter drug or herbal supplement. Potential DDIs and HDIs were identified using two different databases. If a potentially clinically relevant DDI was recognized by the clinical pharmacist, a notification was sent to the prescribing oncologist, who decided whether to carry out a suggested intervention. Regression analyses were performed to identify variables associated with clinically relevant DDIs. 初治癌症患者被要求完成关于同时使用草药或其它药物的调查表。通过两个不同的数据库确定草药-药物交互作用和药物-药物交互作用。如果临床药剂师发现潜在的临床相关的药物交互作用,肿瘤科医师会接到通知并根据情况判断是否需要临床干预。通过回归分析法确定临床相关的药物交互作用。
Results:
A total of 149 patients were included in this study, with 36 potentially clinically relevant DDIs identified in 26 patients (17.4%; 95% CI, 11.3% to 23.5%), all of them leading to therapy modifications. In total, four patients (2.7%; 95% CI, 0.1% to 5.3%) had experienced clinical consequences from DDIs at the time of pharmacist notification. Additionally, 84 patients (56.4%; 95% CI, 48.4% to 64.4%) reported using concurrent herbal supplements, and 122 possible HDIs were detected. Concomitant use of two or more drugs was independently associated with high risk of a clinically significant DDI (odds ratio, 2.53; 95% CI, 1.08 to 5.91; P = .03). 一共有149例患者参加了这项研究,其中26例发生了36项潜在的临床相关的药物交互作用,全部导致了治疗方案的修改。总的来说,有4例在药剂师通知的时候已经产生了药物交互作用的临床后果。此外,有84例报告同时使用了草药补剂,发现了122项可能的药物交互作用。同时使用两个及两个以上药物是独立的发生具有临床意义的药物交互作用的高风险因素。
Conclusion:
Potentially clinically relevant DDIs and possible HDIs were frequently detected in this prospective study. A multidisciplinary approach is required to identify and avoid potentially harmful combinations with anticancer therapy. 这项前瞻性研究证实潜在的临床相关药物-药物和草药-药物交互作用发生率很高。在癌症治疗中需要通过多学科会诊的方式来确认和避免可能带来潜在伤害的联合用药。
