药物与营养素间的相互作用可引起营养缺乏甚至药物中毒等不良后果。在老年人,由于药物长期应用和所用药物的多样化,以及与年龄相关的药物的代谢变化和排泄障碍,都会增加这种相互作用的危险性。此外,在照料老年病人时,某些常用的方法例如为确保病人按时服药,采取就餐时发药的方法,也会增加这种相互作用的危险。 The interaction between drugs and nutrients can cause nutritional deficiencies and even drug poisoning and other adverse consequences. In older people, the risk of this interaction increases because of the long-term drug use and diversification of drugs used, as well as the metabolic changes and excretion disorders of age-related drugs. In addition, when taking care of elderly patients, some commonly used methods, such as ensuring that patients take their medicines on time and taking medicines at meals, also increase the risk of such interaction.
